THK double row angular contact roller shaft ring series

 By making the rolling surface double row and using small diameter rollers, the number of rollers is approximately five times that of the traditional cross roller ring RU type (in the case of using the RW228). While maintaining compactness, rigidity and accuracy are improved, and torque is also reduced. In addition, the inner and outer rings of the integrated structure are provided with mounting holes so that they can be fixed directly to the equipment.
