Introduction

Needle roller and cage assemblies are single or double row units comprising cages and needle rollers.

Since their radial section is no greater than the diameter of the needle rollers, needle roller and cage assemblies allow bearing arrangements with a very small radial design envelope to be achieved. They have very high load carrying capacity, are suitable for high speeds and can be easily fitted.

If the raceways are produced to high geometrical accuracy, bearing arrangements with high runout accuracy can be achieved.

The radial internal clearance can be influenced by the needle roller sort and by the shaft and housing tolerance.

Needle roller and cage assemblies require a hardened and ground raceway on the shaft and in the housing.
