Description

The needle roller and cage assembly is a self-contained bearing element in which each needle roller is precisely guided and held by a cage. It realizes a bearing design with high load capacity and high rigidity in the smallest construction space. The wide distance between the two guide faces of the cage ensures precise guidance of the needle roller and cage assembly.
Needle roller and cage assemblies are suitable where the shaft and housing bore can serve as a raceway. The highest rotational accuracy can be obtained under the shaft and housing raceway with high dimensional accuracy and geometric accuracy.
The working clearance of the shaft part depends on the tolerance of the inner and outer raceways, the difference of the needle roller set and the working temperature.
