Radial Needle Roller K-ZW Series are single or double row units comprising cages and needle rollers.
Since the 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. Radial Needle RollerK-ZW Series 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.
Radial Needle Roller K-ZW Series features
Lowest cross section among rolling bearings
In applications where less space is available, needle roller and cage assemblies offer a very compact solution.
High load carrying capacity
Due to their large number of rollers, needle roller and cage assemblies have a high load carrying capacity.
High stiffness
Due to their large number of small-diameter rollers, needle roller and cage assemblies have high stiffness.
