The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C2-P-1 (R16518222Y) is a high-precision ball runner block designed for linear motion applications requiring high rigidity and precision. This runner block features a size 20 profile with an FNS format, which stands for width flange, normal length, and standard height. The body is constructed from unalloyed steel CS, ensuring durability and strength. Equipped with a medium preload class C and accuracy class P for precision, the runner block is designed to deliver consistent performance with reduced frictional oscillations and low friction force levels, especially when subjected to external loads. The patented entry zone of the runner block increases travel accuracy significantly. The B.RUNNER BLOCK CS KWD-020-FNS-C2-P-1 comes with a ball chain that contributes to a low noise level and optimal travel behavior. It also features lube fittings with metal threads on all sides for easy maintenance and lubrication. The overall length of the runner block is specified in its technical data. For attachment flexibility, it includes end-face fastening threads without attachment elements on the left or right front reference edges. Its straight lube connection is loosely attached for convenience. Additionally, this model boasts integrated all-around sealing to protect against contaminants, enhancing its service life. The Bosch Rexroth ball runner block has been pre-lubricated at the factory for immediate use upon installation. It is compatible with all SN/SNO ball guide rails from Bosch Rexroth and offers high load ratings in all four main loading directions. Long-term lubrication over several years is possible due to its efficient design. With optimized entry-zone geometry and a high number of balls, this runner block minimizes variation in elastic deflection while maintaining high rigidity in all load directions. This allows for applications using just one runner block per rail if needed. Additional mounting screw holes at the center further improve rigidity under lift-off and side loading conditions. Overall, this product represents a versatile solution for various linear motion systems where precision and rigidity are paramount.
