REXROTH FKS block KWD-030-FKS-C1-N-1 R166539422 steel standard ball guide slider

The Bosch Rexroth high-precision steel standard ball linear guide slider R166539422, with the official standard model designation KWD-035-FKS-C0-N-1, belongs to the FKS flange series of Rexroth Ball Rail Systems. It is a short, standard height slider specifically designed for high-precision automation scenarios with limited longitudinal installation space.

R166539422 KWD-035-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.

R166539422 flange-type ball joint sliders are used in the following industrial fields:

Semiconductor and electronics manufacturing: Control board manufacturing equipment and precision assembly lines.

Machine tool industry: Auxiliary mechanisms for various cutting machine tools and forming and separating machine tools.

Automated material handling and logistics: Due to its short-body design and smooth operation, it is often used in space-constrained handling tools, robotic arms, and linear modules.

Light industrial machinery: Such as woodworking machinery (saws), textile machinery, and printing and paper handling equipment.
