RU Cross Roller Bearings

Features: RU Series Crossed roller bearing is Integrated Inner/Outer Ring type
Inner Diameter: 20-350mm Outer Diameter: 70-540mm Width: 12-45mm
RU crossed roller bearing can be used for both inner-ring rotation and outer-ring rotation
ince 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

Characteristics

RU crossed roller bearing characteristics:
1. High precision: P4 precision, P2 precision.
2. High rigidity: This series of bearings have preload.
3. High load: This series of bearings can bear double-direction axial load, radial load and tilting moment.
4. Small size: This series of bearings can save space for machine tools.

RU series crossed roller bearing
(integrated inner and outer rings, high rigidity, with mounting holes)
This series of bearings has the mounting holes on the outer and inner rings, the mounting flange and the support base are not required during mounting of this series of bearings. In addition, since the outer and inner rings are integrated structures, the mounting is virtually no impact on its performance, and the stable running accuracy and torque can be obtained. This series of bearings is especially suitable for application with rotation of outer and inner rings.
