Bearing is a device which looks like a wheel and its function is to assist in linear or rotational movement and while doing so reduce friction and stress. They shut down the friction between bearing surface and the surface that the bearing is rolling over. When friction is reduced, movement over a surface becomes easy. Speed and efficiency of the moving device also enhances.

Types of Roller Bearing

Roller bearing incorporates a cylinder to keep the distance between moving parts of the bearing. The aim of the roller bearing is to support radial and axial loads as well as bring down rotational friction. The roller bearing has the capability to support heavy radial load but when it comes to supporting axial loads, it offers limited support. The most common use for roller bearings is in equipment and conveyor belts.

You can find roller bearings available in various types with each type serving a particular purpose. Here is a look at the many types of roller bearing available in the market:

Cylindrical Bearings – These kinds of bearings are used in heavy equipment and they are the best in operations where the radial load capacity is big and in such situations offer unmatched performance. They are available in row configuration with single row for standard applications and four rows for high radial load needs.

Taper Roller Bearings – The distinct feature about taper bearings is that they have a tapered structure. Both the inner and outer raceways are tapered. They can be used for managing big axial as well as radial loads. You can see them having row configurations with increasing load capacity.

Spherical Roller Bearings – They have a spherical structure and the unique feature here is two set of roller, one which is the common outer raceway and two inner raceways. They are designed to carry heavy axial loads and you can see them being used in situations where there is extreme speed, performance challenges, misalignment, etc.

Thrust Bearings – This type of bearing is designed to take on loads in the direction of the shaft. It is differentiated according to rolling element and raceway shape. They are used in high speed applications, wherein the load is light. These bearings are available in different variations, which enable greater loads to be taken at educed speeds.

Needle Roller Bearings – They are a special type of roller bearings which have thin, cylindrical roller which look like needles. The needles here are four times more than their diameter. They are able to take on both radial and thrust loads.


Selecting any type of roller bearing is based on the purpose for which it is used. It can be used for a small or a large application, but whatever its purpose it will carry out the task for which it is designed which is smooth movement over a surface.

When buying any type of roller bearing, always look for products that are branded and which have corrosions free properties as this ensure long life and smooth maintenance.
