THK RU and RUV Series Cross Roller Ring

The THK RU Series has an integrated inner and outer ring design with mounting holes on both rings, so it doesn’t need a special flange or housing to install. This mitigates the impact of housing accuracy on performance, giving stable, accurate rotation and torque, and it can be used for both inner ring and outer ring rotation. Model RU uses a spacer retainer for a low friction coefficient and stable rotational torque, with a basic dynamic load rating from 7.35 kN to 222 kN. Model RUV is the full roller version, suited to low speed rotary operations under higher loads and compatible with all-metal specifications, rated from 9.45 kN to 280 kN.

This series is a practical option where you want the accuracy of a cross roller ring without the added mounting components a separable design usually needs.
