This series is an ultra-thin wall structure suitable with mounting holes for extremely limited structural situations，integral inner and outer rings with mounting holes, as both the outer and inner rings have mounting holes, there is no need to fix the flange and support during installation seat. In addition, due to the overall structure of both the outer and inner rings, installation has almost no impact on performance, thus achieving stable rotational precision degrees and torques. Suitable for situations where the outer and inner rings rotate.
