The inner surface of the outer race allows smooth operation of linear and rotary motions while maintaining a uniform load distribution. NB Slide Rotary series is completely interchangeable with SM type Slide Bush, SMK type Flanged Slide Bush and Slide Units such as SMA(W) type, AK(W) type and SMP type. NB Slide Rotary Bush is composed of retainer fitted into cylindrical steel outer race and is designed to guide steel balls for smooth circulation in its retainer. The retainer is also designed to rotate freely towards radial direction and offers smooth linear and rotary motions. > Figure F-3 Structure of SRE-type NB slide rotary bush The use of comparatively large diameter steel balls enhances acceptability of high load capacity. > outer raceretainerball ellementslinear motionrotationside ring The positioning of the steel balls in a cylindrical formation inside the retainer enables a smooth rotational motion to be achieved independent of the installation direction.
