RB

Key Features:

• Integral inner ring, split outer ring design without mounting holes, suitable for inner/outer ring rotation.
• Lightweight and compact structure, with minimal thickness where possible.
• High rigidity due to vertical arrangement of the inner and outer rings.
• Special design with cylindrical rollers in a 90° V groove allows a single bearing to withstand all axial, radial, and moment loads.

RB crossed roller bearings employ a split-type design between the inner and split outer rings, ensuring balanced rotational torque and automatic adjustment of clearance under pressure to prevent roller lock-up, maintaining high precision rotation. They are particularly suited for applications demanding high rotational precision in environments such as industrial robots, machinery, and medical facilities where high rigidity, compactness, and high-speed operation are required. RB crossed roller bearings achieve high rotational efficiency and low heat generation, resulting in reduced lubricant consumption.
