R162329420 KWD-025-SLS-C0-N-1 Bosch Rexroth Ball Runner Block Carriage

The Bosch Rexroth KWD-025-SLS-C0-N-1 is a long-body slimline ball runner block designed for large linear motion systems requiring high stability, smooth running and a compact installation width. The SLS configuration — slimline width, long block length and standard height — provides enhanced running smoothness and reduced deflection over longer travel distances, making it ideal for precision-heavy and high-load applications. Manufactured from robust carbon steel and supplied pre-lubricated, this size-25 block delivers dependable, long-term performance in demanding industrial environments.

Key Features

• SLS format (Slimline / Long length / Standard height) — extended block length provides greater stability, improved load distribution and smoother motion.

• Size 25 — suited to large and heavy-duty industrial applications.

• Carbon steel construction — ensures exceptional rigidity, strength and durability under continuous or heavy loading.

• C0 preload (preload-free) — delivers smooth, low-resistance movement where minimal friction is preferred.

• Accuracy class N — reliable general-purpose precision ideal for automation, CNC and mechanical systems.

• Standard sealing — protects the internal tracks from dust and contaminants in typical workshop environments.

• Pre-lubricated and sealed — ready for immediate installation with no initial maintenance required.

• High static, dynamic and moment load capability — suitable for systems with complex, multi-directional load requirements.

• Compatible with Bosch Rexroth size-25 SLS, SNS and SNH rails.
