RU series

Due to the manufactured mounting hole of RU series,the bearing doesn’t require fixing flange and housing. In addition, the bearing is the best choice for conditions which require high accuracy of inner and outer rings. Because of the integrated inner ring and outer ring, there is no influence on performance while mounting; therefore, high accuracy is acquired. These bearings are suitable to the rotation of outer ring and inner ring.
