Cross-Roller Ring Standard Models RU and RUV

The integrated design of the unit’s inner and outer rings, with mounting holes on both rings,eliminates the need for a special flange or housing and enables easy installation.
Products with spacer retainers (Models RU and RU-H) have a low friction coefficient and demonstrate highly stable rotational torque. Full-Roller products (Model RUV) are suited to low-speed rotary operations with higher loads, and they are also compatible with all-metal specifications.
