Roller bearing types and areas of application


 Roller bearings – also known as roller bearings – are similar to ball bearings in that they are designed to carry loads while minimizing friction.

However, roller bearings transfer the load using cylindrical rolling elements instead of balls to maintain the distance between the moving parts of the bearing. These versatile bearings can contain one or more rows of rolling elements. Those roller bearings that contain several rows of rolling elements can significantly improve the radial load capacity. In addition, the use of different roller shapes can further reduce friction and support both radial and axial loads.

Roller bearing types and areas of application


Roller bearing types and their application

Thousands of different types of roller bearings are available to meet specific application requirements.

There is a wide variety of roller bearings, including the following popular types:

Spherical roller bearings

These can carry heavy loads even if they struggle with displacement and shaft deflection. They can be designed with cylindrical or conical bores, which can be fitted with or without a sleeve adapter. Spherical roller bearings, available with various internal clearances and mounting options, can handle axial loads in both directions as well as high impact loads. These bearings are available in bore sizes from 20 mm to 900 mm


Roller bearings

These bearings have rollers that are longer than their diameter and can withstand higher loads than ball bearings. Cylindrical roller bearings can withstand high radial loads and can be used in high speed applications.



Needle roller bearings

This type of bearing is thinner than conventional roller bearings and can be designed with or without an inner ring. Needle roller bearings are ideal for handling radial loads in high-load, high-speed applications. These bearings are used with either inch or metric seals.

Tapered roller bearings

These bearings can support both radial and thrust loads. They can only handle unidirectional axial loads, so a second laterally reversed bearing is required for counter-support. Tapered roller bearings are available in inch and metric sizes.

Roller bearings are used in a wide range of applications, from heavy equipment and machinery to power generation, manufacturing and aviation.

What are plain bearings and what is their purpose?

Kép
 Plain bearings (e.g. bushings, ball joints) facilitate linear movement between two parts. Plain bearings consist of metal, plastic, or fiber-reinforced composite sleeves that reduce vibration and noise by absorbing friction between two moving parts in a sliding motion. Plain bearings have many advantages, including lower cost, less maintenance, and a large reduction in low-speed operation. The performance of sliding bearings is also characterized by a higher load capacity, especially due to their larger contact zone. Plain bearings with conformal liners compensate for misalignment problems and vibration damping. Plain bearings can be made of bronze, steel or stainless steel. Brass bearings and plastic sleeve bearings are also manufactured for certain applications. A common type of plain bearing that works well in applications that require constant lubrication are bronze bearings, which sometimes include grease plugs (PTFE or graphite) to solve lubrication problems.
