The RB type is a basic model of crossed roller bearing featuring a split outer ring and an integrated inner ring. It is especially suitable for applications that require high rotational accuracy of the inner ring. For example, it is widely used in the rotary sections of indexing tables in machine tools.
Product Features:
Crossed roller bearings consist of two rows of cylindrical rollers arranged orthogonally at 90° on V-shaped raceways, with nylon spacers separating the rollers. This structure enables the bearing to simultaneously withstand radial loads, axial loads, and moment loads from multiple directions. The dimensions of both the inner and outer rings are compact, and the ultra-thin type approaches the minimum possible size while still maintaining high rigidity. BYC Boying crossed roller bearings can achieve precision up to P2 grade.
Applications:
Robot joints, direct-drive torque motors, precision inspection instruments, precision rotary tables, and similar high-accuracy rotary systems.
