Needle Roller Axial Cylindrical Roller Bearings

Needle roller/axial cylindrical roller bearings can support axial forces in one direction as well as high radial forces. Using this type to support axial forces from alternating directions, two bearings must be adjusted against each other.

These bearings comprise a radial needle roller bearing and an axial cylindrical roller bearing. They do not have an inner ring but have a hardened and ground shaft raceway. If the shaft cannot be used as a rolling bearing raceway, inner rings IR can be used instead.

Standard Cylindrical roller bearings have a single or multiple row rolling element set based on cylindrical rollers. Depending on the design of the ribs on the bearing rings axial forces can be supported in one or both directions.

Cylindrical roller bearings transmit higher forces and have greater rigidity.

INA Single and double row axial cylindrical needle roller bearings are particularly suitable where:

– High axial and shock loads occur in one direction but no radial loads are present;

– The load carrying capacity of the corresponding axial deep groove ball bearings is no longer adequate; 

– The bearing arrangement must have very high axial rigidity;

– The axial space available is very small

– The bearing arrangement can be configured, where the axial space is very small, as a direct bearing arrangement; 

– The bearing parts can or must be mounted separately;

– The bearing arrangement is not configured in itself but, for cost reasons, ready-to-fit standard bearings are to be used.

There are numerous Industrial and commercial applications for Needle Roller axial cylindrical roller bearings in Medical, Office automation, and machine tool manufacturing to name a few.
