The structural feature of BCRB/BRBC series crossed roller bearings is that the outer ring is split type, the inner ring is an integrated design, and there is no cage, but a full complement of roller design. This structure enables the bearing to provide higher rotation accuracy, and is especially suitable for parts that require higher rotation accuracy of the inner ring.

Note
1) The standard inner and outer diameter dimensional accuracy of BRA, BRB, BRE and BRU is grade O, if you need higher precision than grade 0, please consult BYC Boying Bearing.
2) dm represents the arithmetic mean of the maximum diameter and the minimum diameter obtained by two-point measurement of the inner diameter of the bearing Dm represents the arithmetic mean of the maximum diameter and the minimum diameter obtained by two-point measurement of the outer diameter of the bearing.
3) In the table, the precision grades of the inner diameter or outer diameter of the bearings are not indicated by numerical values, and the highest numerical values are also applicable to lower precision grades.
