The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C2-X-1 (R16518282Z) is a high-precision ball runner block designed for linear motion applications that require rigidity, precision, and smooth operation. This model is part of the Ball Rail Systems product group and features a size 20 runner block body made of unalloyed steel CS. It offers extra precision (accuracy class XP) and an average preload (preload class C), ensuring medium pre-tensioning for optimal performance without a ball chain. The runner block's dimensions include a standard width, normal length, and standard height in the FNS format, with an overall length specified by the manufacturer. The dynamic load capacity (C), static longitudinal moment load capacity (ML), and dynamic torsional moment load capacity (Mt) are determined based on DIN ISO standards to ensure reliable operation under various loading conditions. Notably, this Bosch Rexroth runner block is designed with interchangeability in mind, allowing compatibility with guide rails across different accuracy classes. Its robust construction includes integrated all-around sealing and high torque load capacity, suitable for applications that demand one runner block per rail. Additionally, it features mounting flexibility with attachments that can be installed from above or below and lube fittings with metal threads on all sides. Pre-lubricated at the factory with roller bearing grease Dynalub for initial use and long-term maintenance possibilities, this model ensures reduced frictional oscillations and low friction levels even under external loads. The patented entry zone increases travel accuracy significantly. For enhanced system rigidity, two additional mounting screw holes are provided at the center of the block. This Bosch Rexroth ball runner block can be used on all SNS/SNO Ball Guide Rails and supports various ambient temperature ranges for diverse application environments. It is also equipped to handle high load ratings in all four main directions of loading due to its design and construction quality.
