Product Description

HBB High Accuracy Crossed Cylindrical Roller Bearing


Crossed Roller Bearings consist of an outer ring, an inner ring, and a plurality of rollers and spacers. The roller lies between the inner and outer ring with the spacers placed between the rollers to prevent the mutual friction between them thereby decreasing the torque resistance for rotation. 

There are 4 types of Crossed Roller Bearings comprising of, the compact split outer ring type (HRA), the basic split outer ring type (HRB), the split inner ring type (HRE), the high rigidity type with mounting holes(HRU).
