R162229420 KWD-025-SNS-C0-N-1 Bosch Rexroth Ball Runner Block Carriage

The Bosch Rexroth KWD-025-SNS-C0-N-1 is a slimline, high-performance ball runner block designed for large linear motion systems requiring a narrow installation width combined with excellent load capacity and smooth running characteristics. Its SNS configuration — slimline width, normal block length and standard height — provides a compact carriage suitable for constrained spaces while maintaining the robustness and precision expected of a size-25 system. Manufactured from durable carbon steel and supplied pre-lubricated, this block offers long service life with minimal maintenance.

Key Features

• SNS format (Slimline / Normal length / Standard height) — ideal for applications requiring a narrow carriage profile without sacrificing stability or load capacity.

• Size 25 — built for heavier-duty industrial applications with high load and rigidity requirements.

• Carbon steel body — offers excellent strength, rigidity and long-term performance under demanding load conditions.

• C0 preload (preload-free) — provides very smooth, low-resistance movement where preload stiffness is not required.

• Accuracy class N — dependable standard precision for general industrial, automation and machinery use.

• Standard sealing — protects the internal ball tracks from dust and typical contaminants.

• Pre-lubricated and sealed — ready for installation straight out of the box, with minimal initial maintenance.

• High load and moment capacity — withstands multi-directional forces and dynamic loading environments.

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