NB's Slide Rotary Series consists of three different types. The Slide Rotary Bush, which provides both endless rotary and linear motion functions, the Flanged Slide Rotary Bush, and the Slide Rotary Unit which is assembled using various NB standard housings.The NB Slide Rotary Series has an idealistic structure, incorporating a combination of linear and rotary motion. Linear and rotary motion are merged into a single unit resulting in great space savings compared to the conventional style of Slide bushings. All three types of the Slide Rotary Series are available in sizes ranging from 6mm to 30mm. All components in the Slide Rotary Series are standardized for versatile installation requirements.Smooth Operation

STRUCTURE AND ADVANTAGES

Complete Interchangeability

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.

High Load Capacity

Smooth Rotation

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. F-8
