R162111320 KWD-015-SNH-C1-H-1 Bosch Rexroth Ball Runner Block Carriage

The Bosch Rexroth KWD-015-SNH-C1-H-1 is a high-precision linear motion runner block designed for applications that demand increased stiffness, accuracy and long-term reliability. Built in the SNH format (slimline width, standard length, high height), this block offers excellent rigidity while remaining compact enough for installations with limited transverse space.

Manufactured from durable carbon steel and supplied pre-lubricated, it delivers smooth, accurate movement with very low friction — ideal for CNC machinery, automation systems and any precision-driven linear motion setup.

Key Features

• SNH body design: Slim width for tight spaces, standard length for balanced running stability, and increased height for higher rigidity.

• Size 15: Compact but capable of carrying significant loads for its footprint.

• Carbon steel construction: Robust, stiff and reliable under continuous industrial use.

• Low preload (C1): Improved vibration resistance and reduced clearance without generating excessive internal stress.

• High accuracy class (H): Offers tighter tolerances and greater positioning precision than standard class N blocks.

• Pre-lubricated and sealed: Ready for installation and designed for long running life with reduced maintenance downtime.

• Smooth-running recirculating ball system: Minimises frictional noise and delivers consistent travel accuracy.

• Fully compatible with Bosch Rexroth SN and SNO guide rails of matching size and accuracy.

Specifications 

The nominal size is 15, making this runner block suitable for compact linear motion systems.
The overall block height is increased due to the SNH configuration, offering better rigidity and load absorption.
The block body is manufactured from high-grade carbon steel, ensuring strength and minimum deformation under load.
It uses a C1 preload, which reduces internal play and improves stability during high-precision movements.
The accuracy class is H, meaning the block provides a tighter travel tolerance and improved repeatability versus standard grades.
The block is supplied fully lubricated and corrosion-protected, allowing immediate installation for both new builds and retrofit projects.
The KWD-015-SNH-C1-H-1 is designed to handle high dynamic and static loads relative to its size, with load capacity performance suitable for single-block-per-rail setups.
It supports an operating temperature range typically between –10°C and +80°C, making it suitable for most industrial environments.
Mounting is via the standard Bosch Rexroth top-mount bolt pattern for SNH blocks, ensuring straightforward integration with size-15 rails.
The block features standard sealing, offering protection against dust, chips and general contamination.

Typical Applications

• CNC machining equipment, engraving machines and router systems

• Automation lines and assembly machinery

• Industrial robotics requiring high repeatability

• Precision positioning units and pick-and-place systems

• Packaging and processing equipment

• Retrofit upgrades of existing Bosch Rexroth size-15 rail systems
