CRBH Series Crossed Roller Bearings

The CRBH series cross roller bearing structure is designed to integrate the inner and outer rings, which saves installation space significantly. The integral ring raceway has a system for bearing ball insertion on the outer ring, and such a structure features high rigidity and good rotation accuracy. The sealed series can achieve the effect of sufficient lubrication.

CRBH Series Crossed Roller Bearings

The inner ring and outer ring of the CRBH series crossed roller bearings are all integrated structures. Their overall sizes are utterly the same as RB and RE series crossed roller bearings, but its outer ring has hole type structure for installing bearing rollers, so both the inner ring and outer ring can achieve high rotation accuracy; thus, both the bearing inner ring and the outer ring is available to rotate.

The inner and outer rings are ultra-thin. Due to the ultra-thin design and the outer ring and inner ring without mounting holes, the mounting requires the flange and the support to be fixed. In addition, since the outer ring and the inner ring are both integral structures, the mount does not affect the performance, so stable rotation accuracy and torque can be obtained, which is suitable for the outer ring and the inner ring to rotate. Still, there are occasions when the size is small.
