The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C2-S-1 (R16538212Z) is a high-precision ball runner block designed for linear motion applications requiring superior rigidity and accuracy. This runner block is part of the Ball Rail Systems product group and features a size 20 flange (FLS), with a long body length, standard height, and is constructed from unalloyed steel CS. It boasts an accuracy class of SP (super precision) and a medium preload class C, indicating an average preload without the inclusion of a ball chain. The B.RUNNER BLOCK CS KWD-020-FLS-C2-S-1 is characterized by its ability to handle demanding rigidity requirements while maintaining low frictional oscillations and force levels, especially under external loads. Its dynamic characteristics are exceptional due to the patented entry zone that can improve travel accuracy by up to six times. It's also designed for long-term lubrication spanning several years, featuring lube fittings with metal threads on all sides for ease of maintenance. This model supports high torque load capacity and offers various preload classes to suit different application needs. The rigidity is enhanced in all load directions, allowing use with just one runner block per rail if necessary. Additional mounting screw holes at the center increase rigidity under lift-off and side loading conditions. The B.RUNNER BLOCK CS KWD-020-FLS-C2-S-1 ensures maximum system rigidity through its preloaded O-arrangement and provides optional integration of an inductive, wear-free measuring system. Attachments can be mounted from both above and below the runner block. It's compatible with all SN/SNO ball guide rails, maintaining high load ratings in all four main loading directions. Pre-lubricated at the factory for immediate use, this ball runner block also includes integrated all-around sealing for protection against contaminants. The design allows for straightforward end-face fastening thread attachment, further enhancing its versatility across various applications while ensuring optimal performance in precision-driven linear motion tasks.
