They can be defined as a component that permits only a specific type of motion in a system that may be under static or dynamic loading. When two metal parts come in contact inside a machine, a large amount of friction is produced, and this can lead to the wear and tear of the material in time.<\/span><\/p>\n<p>A bearing is a mechanical component that helps a rotating assembly move smoothly. As a result, the bearing permits one element to rotate relative to another.

From a design perspective, the <\/span><span style=\"font-weight: 400;\">classification of bearings<\/span><span style=\"font-weight: 400;\"> is as follows.<\/span><\/p>\n<h3>Plain Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Also referred to as bushes, bushings, or sleeve bearings, these are the simplest type of bearings. With a cylindrical shape and no moving parts, they are usually used in machines with a rotating or sliding shaft component. Plain bearings can be made of metal or plastic and can use a lubricant-like oil or graphite for reducing the friction between the shaft and the hole it rotates in. Typically, they are used for sliding, rotation, oscillating or reciprocating motion. Plain bearings are further classified into the following sub-types:<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9475\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Spherical-Plain-Bearings.jpg\" alt=\"Different Types of Bearings\" width=\"700\" height=\"776\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Spherical-Plain-Bearings.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Spherical-Plain-Bearings-271x300.jpg 271w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Spherical-Plain-Bearings-696x772.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Spherical-Plain-Bearings-379x420.jpg 379w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<h3>Spherical Plain Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Spherical plain bearings are <\/span><span style=\"font-weight: 400;\">types of bearings<\/span><span style=\"font-weight: 400;\"> that have an inner ring with a convex outside surface and an outer ring with a concave inside surface. The two rings are mounted together, so there are no rolling elements in between. However, depending on the materials used for the rings, a layer of coating made of chromium, PTFE, or phosphate can be applied for reducing the wear. In some designs, seals can be added to reduce contamination and extend the bearing life.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Spherical plain bearings are suitable for applications where alignment movements between the shaft and housing have to be accommodated. When they can withstand heavy loads and shocks, they are also referred to as heavy-duty spherical plain bearings.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9476\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Rod-End-Bearings.jpg\" alt=\"Different Types of Bearings\" width=\"700\" height=\"700\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Rod-End-Bearings.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Rod-End-Bearings-300x300.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Rod-End-Bearings-150x150.jpg 150w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Rod-End-Bearings-696x696.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Rod-End-Bearings-420x420.jpg 420w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<h3>Rod End Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Rod end bearings also referred to as Rose joints, consist of an eye-shaped head with an integral shank, which is used as housing for a spherical plain bearing. The internal thread is usually left- or ring-hand female, while the external thread is male.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The bearing is fixed inside the housing, so unlike spherical plain bearings, which offer misalignment capabilities, rod ends don&#8217;t have this characteristic. They are, however, very easy to mount, provide a compact and lightweight design, and are a good alternative to a conventional housing element. Rod end bearings are often used in control rods, mechanisms, and linkages, being easy to integrate into various applications.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9477\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Bushings.png\" alt=\"Different Types of Bearings\" width=\"700\" height=\"496\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Bushings.png 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Bushings-300x213.png 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Bushings-696x493.png 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Bushings-593x420.png 593w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Bushings-100x70.png 100w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<h3>Bushings<\/h3>\n<p><span style=\"font-weight: 400;\">The most common type of plain bearing is the bushing or bush, which is an independent element inserted into a housing to provide a supporting surface. The shape is usually cylindrical, the standard configurations being the sleeve bearing and the flanged bearing. Sleeve bearings have straight inside and outside surfaces and equal diameters, while the flanged ones have a flange at one end that is used for locating the element in an assembly, and sometimes also for covering the mounting holes and securing the bearing in place.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A particular type of bushing is <\/span><b>self-lubricating bushing<\/b><span style=\"font-weight: 400;\">, in which a solid lubricating film is created inside the bearing through the transfer of a small amount of surface material. This happens in the initial run-in period of the bearing, but the amount of material transferred is small enough to not interfere with the functioning and load-handling properties of the bearing.<\/span><\/p>\n<h3>Two-piece Plain Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Also referred to as full bearings, two-piece plain bearings are used in industrial machinery where larger diameters are required, such as crankshaft bearings. They are made of two parts called shells, which are kept in place using different mechanisms.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If the shells are large and thick, a button stop or a dowel pin can be used for locating them. The button stop is screwed on the housing, and the dowel pin links the two shells together. Another possibility is to use a tab on the parting line edge that correlates with a notch in the housing, to prevent the movement of the shells after installation.<\/span><\/p>\n<h3>Rolling-element Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Rolling-element bearings are also called anti-friction bearings, as they have lower friction and reduced lubrication requirements compared to plain bearings. Their role is to support and guide rotating and oscillating machine elements, such as shafts, wheels, or axels, and to transfer loads between the different components of an assembly.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">They come in standard sizes, are easy to replace, and cost-effective. By minimizing friction and enabling high rotational speeds, these bearings reduce heat and energy consumption, leading to more efficient processes. Rolling-element bearings fall into two main categories: Ball bearings and roller bearings.<\/span><\/p>\n<h3>Ball Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Ball bearings are probably the most common type of bearings that utilize balls as the rolling elements. They are characterized by point contact between the balls and the raceways.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As a rule, ball bearings rotate very quickly but cannot support substantial loads, so if the bearing is overloaded, the balls can deform or squish, ruining the bearing.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Ball bearings are used in a variety of applications, from simpler devices like skateboards to complex machines or engines including electric motors and generators, pumps and compressors, blowers, fans, gearboxes and drives, turbines, farm machinery, conveying systems, oil field machinery, robotics, industrial valves and so on. Ball bearings are further classified into the following sub-types:<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9478\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Deep-Groove-Ball-Bearings.jpg\" alt=\"Different Types of Bearings\" width=\"700\" height=\"718\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Deep-Groove-Ball-Bearings.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Deep-Groove-Ball-Bearings-292x300.jpg 292w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Deep-Groove-Ball-Bearings-696x714.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Deep-Groove-Ball-Bearings-409x420.jpg 409w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Deep-Groove-Ball-Bearings-356x364.jpg 356w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<p>&nbsp;<\/p>\n<h3>Deep-Groove Ball Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">The most commonly used <\/span><span style=\"font-weight: 400;\">types of ball bearings<\/span><span style=\"font-weight: 400;\"> are Deep-Groove Ball Bearings. Thanks to their simple design, they are easy to maintain and not as sensitive to operating conditions thus are used in a wide range of different applications.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Deep groove ball bearings are robust in operation and require little maintenance. In addition to radial forces, they can accommodate radial loads and axial loads in both directions. Their low torque also makes them suitable for high speeds. These ball bearings are available as open-type bearings that allow for easy lubrication but have the disadvantage that the balls can collect dust.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9479\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Angular-Contact-Ball-Bearings.jpg\" alt=\"Different Types of Bearings\" width=\"700\" height=\"393\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Angular-Contact-Ball-Bearings.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Angular-Contact-Ball-Bearings-300x168.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Angular-Contact-Ball-Bearings-696x391.jpg 696w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<h3>Angular Contact Ball Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Angular Contact Ball Bearings are characterized by a contact angle. This means that forces are transferred from one raceway to the other at a particular angle.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Angular contact ball bearings are therefore suitable for combined loads, where high axial forces have to be transferred in addition to radial forces.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Angular contact bearings can come in different design styles, with seals or shielding. These serve not only as protection from contamination but also as retainers for lubricants. These bearings can be made from stainless steel, ceramic hybrid materials, or plastic, and may be plated with chrome, cadmium, or other materials. Also, they can be pre-lubricated, re-lubricated, or can feature solid lubrication.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9480\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Self-Aligning-Ball-Bearings.jpg\" alt=\"Different Types of Bearings\" width=\"700\" height=\"591\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Self-Aligning-Ball-Bearings.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Self-Aligning-Ball-Bearings-300x253.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Self-Aligning-Ball-Bearings-696x588.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Self-Aligning-Ball-Bearings-497x420.jpg 497w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<h3>Self-Aligning Ball Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Self-Aligning Ball Bearings are <\/span><span style=\"font-weight: 400;\">types of bearings<\/span><span style=\"font-weight: 400;\"> that include a double row of balls guided by a cage and double row inner ring raceway but have the special feature of a continuous spherical outer ring raceway allowing the inner ring\/ball complement to swivel within the outer ring. This is what enables a degree of self-alignment in the application.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This type of bearing is recommended when the alignment of the shaft and the housing (misalignment) are a problem and the shaft could deflect. Self-aligning ball bearings are most suitable for absorbing radial forces.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9481\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Thrust-Ball-Bearings.jpg\" alt=\"Different Types of Bearings\" width=\"700\" height=\"393\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Thrust-Ball-Bearings.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Thrust-Ball-Bearings-300x168.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Thrust-Ball-Bearings-696x391.jpg 696w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<h3>Thrust Ball Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Thrust Ball Bearings consist of two bearing discs with raceways for the balls.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Thrust ball bearings were developed solely for absorbing axial forces in one direction, meaning they can locate the shaft axially in one direction.<\/span><\/p>\n<h3>Roller Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Roller Bearings are <\/span><span style=\"font-weight: 400;\">types of bearings <\/span><span style=\"font-weight: 400;\">characterized by line contact. Line contact offers a higher load rating than ball bearings of the same size; however, the speed ability is lower than a ball-bearing due to the increased friction of a contact line.

If space is constricted, needle bearings can be a good solution.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The smallest and lightest of the roller bearing family, needle roller bearings are widely used in the automotive industry, in components such as compressors, transmissions, rocker arm pivots, or pumps. These bearings are also commonly used in agricultural applications and construction equipment, in portable power tools, and in domestic appliances.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9486\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Jewel-Bearings.jpg\" alt=\"Different Types of Bearings\" width=\"700\" height=\"466\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Jewel-Bearings.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Jewel-Bearings-300x200.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Jewel-Bearings-696x463.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Jewel-Bearings-631x420.jpg 631w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<h3>Jewel Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Jewel Bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole. The hole is typically shaped like a torus and is slightly larger than the shaft diameter. The jewel material is usually synthetic sapphire or ruby. Jewel bearings are used in precision instruments where low friction, long life, and dimensional accuracy are important such as mechanical watches.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9487\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Fluid-bearing.jpg\" alt=\"Different Types of Bearings\" width=\"700\" height=\"845\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Fluid-bearing.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Fluid-bearing-249x300.jpg 249w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Fluid-bearing-696x840.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Fluid-bearing-348x420.jpg 348w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<h3>Fluid Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Fluid Bearings are <\/span><span style=\"font-weight: 400;\">types of bearings <\/span><span style=\"font-weight: 400;\">in which the load is supported by a thin layer of rapidly moving pressurized liquid or gas between the bearing surfaces. Since there is no contact between the moving parts, there is no sliding friction, allowing fluid bearings to have lower friction, wear, pressurized and vibration than many other types of bearings.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">They are also increasingly being used to cut costs. Fluid bearings are used in machines that work at high speeds and loads. While the initial costs are higher, the longer lifespan in tough conditions makes up for it in the longer run.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Fluid bearings are classified into two types: hydrostatic and hydrodynamic bearings.<\/span><\/p>\n<h3>Hydrostatic Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">In this type, an externally pressurized fluid is forced between two elements that are in relative motion. The pressurized fluid forms a wedge between the moving parts and keeps them apart. The fluid layer may be very thin but as long as there is no direct contact, there will not be any wear.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The fluid is circulated using a pump. The exit orifice diameter may be adjustable to ensure the fluid is always under pressure at all shaft speeds and loads. Thus, precise gap control is possible.<\/span><\/p>\n<h3>Hydrodynamic Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">This type of bearing utilizes the motion of the journal to force the fluid between the shaft and the housing. The journal motion sucks the lubricating fluid between the moving parts creating a constant wedge. This, however, means that during start-stop as well as at low loads and speeds, the wedge formation may not be good enough to prevent wear. Only at designed speeds will the system work exactly as needed.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9488\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/magnetic-bearing.jpg\" alt=\"Different Types of Bearings\" width=\"397\" height=\"296\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/magnetic-bearing.jpg 397w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/magnetic-bearing-300x224.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/magnetic-bearing-80x60.jpg 80w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/magnetic-bearing-160x120.jpg 160w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/magnetic-bearing-265x198.jpg 265w\" sizes=\"(max-width: 397px) 100vw, 397px\" \/><\/p>\n<h3>Magnetic Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Magnetic bearings are <\/span><span style=\"font-weight: 400;\">types of bearings<\/span><span style=\"font-weight: 400;\"> that use the concept of magnetic levitation to hold the shaft mid-air. As there is no physical contact, magnetic bearings are zero-wear bearings. There is also no limitation on the maximum amount of relative speed it can handle.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Magnetic bearings can also accommodate some irregularities in shaft design as the shaft\u2019s position is automatically adjusted based on its center of mass. Thus, it may be offset to one side but will still function just as satisfactorily. They are broadly classified into two types: Active and passive magnetic bearings.<\/span><\/p>\n<h3>Active Magnetic Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Active magnetic bearings use electromagnets around the shaft to maintain their position. If a change in position is picked up by sensors, the system adjusts the amount of current being fed to the system and returns the rotor to its original position.<\/span><\/p>\n<h3>Passive Magnetic Bearing<\/h3>\n<p><span style=\"font-weight: 400;\">Passive magnetic bearings use permanent magnets to maintain a magnetic field around the shaft. This means there is no power input needed. The system is, however, difficult to design due to limitations as this technology is still in its early stages.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In many cases, the two types of magnetic bearings may be used in tandem where the permanent magnets handle the static loading while the electromagnets are used to maintain the position to a high degree of accuracy.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9489\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Flexure-Bearings.jpg\" alt=\"Different Types of Bearings\" width=\"700\" height=\"700\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Flexure-Bearings.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Flexure-Bearings-300x300.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Flexure-Bearings-150x150.jpg 150w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Flexure-Bearings-696x696.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/06\/Flexure-Bearings-420x420.jpg 420w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<h3>Flexure Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Flexure Bearings are engineered to be compliant in one or more angular degrees of freedom. Flexure bearings are often part of compliant mechanisms. Flexure bearings serve much of the same function as conventional bearings or hinges in applications that require angular compliance. However, flexures require no lubrication and exhibit very low or no friction.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Another criterion for categorizing bearings is the direction of the load they can accommodate. From this point of view, bearings are grouped into three main categories: radial bearings, thrust bearings, and linear bearings.<\/span><\/p>\n<h3>Radial Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Radial bearings are <\/span><span style=\"font-weight: 400;\">types of bearings <\/span><span style=\"font-weight: 400;\">that primarily used for supporting radial loads, although under some circumstances they are capable of carrying limited thrust loads.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Radial bearings can support loads that fall perpendicularly to the shaft. Depending on the design, they may also accommodate some axial loads, in one or two directions. Radial bearings are installed perpendicularly to the axial line of the shaft.<\/span><\/p>\n<h3>Thrust Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Thrust bearings support loads that are parallel to the bearing axis, so they are designed to withstand forces in the same direction as the shaft (axial loads). Depending on their design, these bearings can handle pure axial loads in one or two directions, and sometimes also some radial loads, but unlike radial bearings, these components cannot accommodate very high speeds.<\/span><\/p>\n<h3>Linear Bearings<\/h3>\n<p><span style=\"font-weight: 400;\">Linear bearings guide the moving parts in a straight line. They are also referred to as linear guides and come in two main shapes: round and square.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Linear bearings are designed to provide a free motion in one direction and offer a smooth precision motion along a single axis linear design. They are most commonly used within the furniture industry as a ball-bearing drawer slide.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">So, this was everything you needed to know about different <\/span><span style=\"font-weight: 400;\">types of bearings <\/span><span style=\"font-weight: 400;\">and the <\/span><span style=\"font-weight: 400;\">application of bearing<\/span><span style=\"font-weight: 400;\">.
