R162389420 KWD-020-SLS-C0-N-1 Bosch Rexroth Ball Runner Block Carriage

The Bosch Rexroth KWD-020-SLS-C0-N-1 is a precision-engineered slimline ball runner block designed for smooth, reliable linear motion in demanding industrial applications. Its SLS configuration (slimline width, long block length, standard height) provides enhanced travel stability and reduced deflection due to the extended block length, while maintaining a narrow profile ideal for restricted installation spaces. Built from high-quality carbon steel and supplied pre-lubricated, this block is ready for long-term, low-maintenance operation.

Key Features

• SLS design (Slimline / Long length / Standard height) — extended length improves stability and load distribution while keeping overall width compact.

• Size 20 — suitable for higher load demands and heavier-duty linear motion systems.

• Carbon steel body — ensures high rigidity, structural strength and long service life.

• C0 preload (preload-free) — provides low rolling resistance and smooth, free-running motion ideal for systems where preload is not required.

• Accuracy class N — offers reliable general-purpose precision for automation, CNC and machinery applications.

• Standard sealing (SS) — effective protection from dust and contaminants for typical industrial environments.

• Factory pre-lubricated and sealed — ready for installation with no initial maintenance required.

• High load and torque resistance in all directions — suitable for applications where loads vary in direction and magnitude.

• Compatible with Bosch Rexroth size-20 SLS, SNS and FLS rails in the same accuracy class.
