Types of Roller Bearing Infographic

Roller bearings are used to replace sliding movement with low friction, rolling motion in rotary applications. The principal types of roller bearings are cylindrical, spherical, and tapered. Roller bearings offer higher load capacities than ball bearings of the same size.

Among many brands, IKO roller bearings are the first choice for OEM and manufacturing industries because of their high quality & load-bearing capacities. Padia enterprise is proud to be one of the IKO bearing distributors in India.

Spherical Roller Bearings

Spherical Roller Bearings are very robust and work on the same principle as Self-aligning bearings with the exception that they use spherical rollers instead of ball rollers allowing higher loads to be supported. This can compensate for misalignments between the shaft and the housing.

Spherical roller bearings are suitable for absorbing high radial loads and moderate axial loads. 

Cylindrical Roller Bearings

Cylindrical Roller Bearings use line contact between the rolling elements and the raceways, which optimizes the distribution of stress factors at the point of contact. This arrangement means that cylindrical roller bearings have a very high radial load rating. Depending on the design, they may also be able to transmit limited amounts of axial loads.

Tapered Roller Bearings

Tapered Roller Bearings have tapered raceways in the inner and outer rings with conical rollers arranged between them. Due to the contact angle, tapered roller bearings can absorb high radial and axial forces in one direction.

Tapered roller bearings are often combined in pairs to support axial forces in both directions.

Needle Roller Bearings

Needle Roller Bearings are a special type of cylindrical roller bearing which contain long, thin rolling elements, known as needle rollers. The ratio of diameter to length is between 1:3 and 1:10. Needle roller bearings have a high load rating and are only suitable for radial forces.

If space is constricted, needle bearings can be a good solution.
