R166529422 FKS ball slider KWD-025-FKS-C0-N-1 Rexroth Slider

The Bosch Rexroth R166529422 FKS linear guide slider (Ball Runner Block) belongs to the BSHR ball guide system. KWD-025-FKS-C0-N-1 is the complete code for the parameters of the R166529422 slider. 25 represents the size specification, FKS indicates that the slider is flange-type with a short slider structure, C0 indicates no preload, and N indicates the standard accuracy class.

R166529422 KWD-025-FKS-C0-N-1 Slider Core Performance Features

**Ball Chain:** The slider incorporates a ball chain. The balls do not collide, resulting in extremely low and uniform friction, significantly reducing operating noise.

**C0 Clearance:** This slider is zero-preload. It exhibits minimal motion resistance and low starting friction, making it suitable for applications requiring high smoothness and uniform external loads.

**N-Class Standard Precision:** Meets the precision requirements of most standard industrial automation and mechanical manufacturing applications.

**Four-Direction Equal Load Capacity:** Bosch Rexroth's unique ball track design ensures identical rated load and extremely high rigidity in the four main load directions: up, down, left, and right.

Typical Applications: Due to its short length, short stroke, built-in silent sliding chain, and low resistance, R166529422 is widely used in:

Precision semiconductor manufacturing and packaging equipment

Medical devices and testing instruments

Small CNC machine tools and lightweight multi-axis robots

3D printing and high-frequency, light-load workstation handling systems
