Overview
The Bosch Rexroth R162211420 is a precision ball runner block designed for demanding linear motion and guidance applications. This KWD-015-SNS-C1-N-1 model combines high rigidity, repeatability, and low friction characteristics that make it essential for machine tools, automation systems, and industrial equipment requiring smooth, reliable linear travel. The block is compatible with all SNS/SNO ball guide rail systems from Bosch Rexroth.
Key Features
- Four-row ball configuration — minimizes friction and provides excellent dynamic characteristics in all loading directions
- Integrated all-round sealing — protects internal components against contaminants during operation
- Factory pre-lubricated — arrives with Dynalub 510 roller bearing grease for immediate installation and extended service intervals
- Standard accuracy (N class) — suitable for precision applications while maintaining cost efficiency
- Moderate preload (C1) — balances load capacity with low friction for general industrial use
- Slimline width design — fits confined spaces without sacrificing load-carrying capability
Technical Specifications
Size 15 format with slimline width, normal length, and standard height. The runner block body is manufactured from unalloyed steel (CS). Preload class C1 provides moderate preload, and accuracy class N delivers standard precision. Overall length is 58.2 mm. The block includes lube fittings with metal threads on all sides and end-face fastening threads for flexible attachment options. It operates with Dynalub 510 roller bearing grease and straight lube connection.
Typical Applications
This ball runner block is ideal for:
- Machine tool tables and slides
- Industrial automation assemblies requiring precision linear motion
- High-rigidity systems where single-block-per-rail mounting is preferred
- Manufacturing equipment with moderate to high load requirements
- Packaging and material handling machinery with positional accuracy demands
