CRBH series crossed cylindrical roller bearings (integral inner and outer rings, ultra-thin) CRBH series crossed cylindrical roller bearings, which is an ultra-thin RU series bearing, due to the ultra-thin design and no mounting holes for the outer ring and inner ring , the installation needs to be fixed by the flange and the support seat. In addition, since the outer ring and inner ring are integral structures, installation has no effect on performance, so stable rotation accuracy and torque can be obtained. It is suitable for occasions where the outer ring and inner ring rotate but require miniaturization.
