Needle Roller & Cage Assemblies are bearing units comprising of a cage and needle rollers that can be supplied in single or double row units.

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 also have very high load carrying capacity, are suitable for high speeds and can be easily fitted.

Providing the raceways are produced to a 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.

The needle rollers are hardened so all needle roller and cage assemblies will require hardened and ground raceways on the shaft and in the housing.
