R162429420 KWD-025-SLH-C0-N-1 Bosch Rexroth Ball Runner Block Carriage

The Bosch Rexroth KWD-025-SLH-C0-N-1 is a high-profile slimline ball runner block designed for large linear rail systems requiring narrow installation width, increased rigidity and excellent moment load resistance. The SLH configuration — slimline width, long block length and high block height — provides enhanced stiffness, reduced deflection and improved stability over longer travels. Constructed from premium carbon steel and supplied pre-lubricated, this size-25 runner block is ideal for demanding industrial environments where precision, strength and long service life are essential.

Key Features

• SLH format (Slimline / Long length / High block height) — long-body design improves running stability, while the high block height enhances rigidity and moment load capacity.

• Size 25 — suitable for large, heavy-duty linear motion applications.

• Carbon steel body — ensures outstanding strength, rigidity and resistance to deformation under high load.

• C0 preload (preload-free) — offers very smooth, low-friction movement where minimal resistance is desired.

• Accuracy class N — dependable standard precision suitable for general industrial and automation applications.

• Standard sealing — protects internal ball tracks from dust and contamination.

• Pre-lubricated and sealed — supplied ready to install with no initial servicing required.

• High static, dynamic and moment load ratings — suitable for multi-directional loads and heavy-duty linear motion systems.

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