BRU (CRBF) series crossed roller bearings do not require fixing flanges and support seats because the mounting holes have been processed. In addition, due to the integrated inner and outer ring structure with seats, installation has little effect on performance, so stable rotation accuracy and torque can be obtained, and it can be used for outer ring and inner ring rotation.
