Multi-row and simple! Achieving high rigidity, high precision, and compactness! Direct fixation without the need for a holding flange!
By multiplexing the rolling surface and adopting small-diameter rollers, the number of rollers is approximately five times greater compared to the conventional cross roller ring "RU." While maintaining compactness, rigidity and precision have been improved, and torque reduction has also been achieved. Additionally, the integral structure of the inner and outer rings is equipped with mounting holes, allowing for direct fixation to the device.

basic information
[Features] ○ High rigidity and high precision → The inner and outer rings are designed as a single structure, achieving high component rigidity. The inner and outer rings have mounting bolt holes processed, and by optimally designing the size and number of these bolt holes, deformation of the rolling surface due to installation is minimized, resulting in stable rotational performance. Additionally, improvements in processing precision enable high rotational accuracy. ○ Low torque → By adopting small-diameter rollers, the friction coefficient is reduced, achieving low torque and low temperature rise characteristics. ○ Increased rigidity → While maintaining almost the same dimensions as conventional products*, the number of raceway rows has been doubled and a DB structure has been implemented, enhancing rigidity. * THK's cross roller ring RU type
