HRU crossed roller bearing series（Integrated Inner/Outer Ring type） Since the mounting holes are provided, the model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque. 

HRU crossed roller bearing can be used for both inner-ring rotation and outer-ring rotation.

HRU crossed roller bearing characteristics:

1. High precision: P4 precision, P2 precision

2. High rigidity: This series bearing have preload

3. High load：This series bearing can bear double-direction axial load, radial load and tilting moment

4. Small size: This series bearing can save space for machine tools

Inner Diameter: 20-350mm

Outer Diameter: 70-540mm

Width: 12-45mm

Weight: 0.29-35.4kg
