Radial Needle Roller & Cage Assemblies

Product Details

Product Details:  Needle Roller Bearing

The needle roller and cage assemblies are self-contained, ready-to-install bearings. In applications where the shaft and housing bore can be used as raceways, the assembly can be used to create a bearing arrangement that requires minimal radial space.

The radial needle roller and cage assembly has a steel cage that provides inward and outward retention of the needle. These designs provide the maximum cage strength consistent with the inherent high load of needle bearings.

Precise guiding of the needle through the cage rod allows high speed operation. The needle roller and cage assembly has one or two rows of needle rollers.

Bearing function:

The lowest cross section in a rolling bearing

The needle roller and cage assemblies offer a very compact solution in applications where space is at a premium.

High carrying capacity

Due to the large number of rollers, the needle roller and cage assemblies have a high load carrying capacity.

High stiffness

The needle roller and cage assemblies have high stiffness due to their large number of small diameter rollers.
