RUシリーズクロスローラーベアリング

RU series 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.

RU Series Crossed Roller Ring Features

1. Integrated inner ring and outer ring provide high stiffness.
2. Sustain radial, axial, and moment loads simultaneously.
3. High rigidity & rotation accuracy. Its compact structure can also reduce the influence of the installation.
4. Miniaturization. Inner ring and outer ring with mounting holes, so it can be easily mounted to a device with bolts without need for housing and fixing plate, so surrounding parts of the bearing can be made compact, contributing to miniaturization and a weight saving of devices.
