The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C1-S-1 (R165381122) is a high-precision ball runner block designed for linear motion applications requiring exceptional rigidity and accuracy. This runner block features a size 20 profile with an FLS format, indicating a flange width, long length, and standard height. The body of the runner block is constructed from unalloyed steel CS, ensuring durability and stability under various operating conditions. With a preload class C, this product offers low preload to reduce frictional resistance while maintaining system stability. Its super precision accuracy class SP ensures maximum travel accuracy for demanding applications. The inclusion of a ball chain contributes to reduced noise levels and smoother travel behavior. This model comes prelubricated with roller bearing grease Dynalub for initial operation and includes preservation measures to maintain its performance over time. It boasts high rigidity in all load directions, which allows for the use of just one runner block per rail in certain applications. Additionally, it features two extra mounting screw holes at the center for enhanced rigidity under lift-off and side-loading conditions. The B.RUNNER BLOCK CS KWD-020-FLS-C1-S-1 also supports various sealing options such as SS standard seal, LS low-friction seal, DS double-lip seal, front seal options, and FKM seals to protect against contaminants like dirt, chips, and coolants. These seals ensure an extended service life by preventing ingress into the internal mechanisms of the runner block. Overall length of this runner block is tailored to provide maximum system rigidity due to its preloaded O-arrangement configuration. Attachments can be mounted from both above and below the runner block body for flexible installation options. This model can be utilized on all SN/SNO ball guide rails by Bosch Rexroth and offers high load ratings in all four main directions of loading. It is designed to accommodate various ambient temperature ranges while maintaining its dynamic load capacity C as per DIN ISO standards.
