The Bosch Rexroth B.RUNNER BLOCK CS KWC-020-FNN-C0-H-2 (R169389310) is a high-precision ball runner block designed for linear motion applications requiring maximum precision and minimal friction. This runner block is part of the Ball Rail Systems from Bosch Rexroth, known for their robust design and interchangeability with guide rails to suit various accuracy requirements. The B.RUNNER BLOCK CS KWC-020-FNN-C0-H-2 features a size FNN format, which indicates a flange width, normal length, and low height. It is constructed from unalloyed steel CS, ensuring durability and strength. The runner block operates without preload (preload class C), meaning there is no pre-tension on the ball bearings, which can be advantageous in certain applications. It boasts a high accuracy class H, ensuring precise movements. This model does not include a ball chain and comes preserved but without initial lubrication or attachment elements at the front reference edges. Lube fittings with metal threads are provided on all sides for maintenance purposes, and the unit allows for end-face fastening of attachments. The integrated all-around sealing offers protection against contaminants while maintaining low friction levels. The optimized entry-zone geometry combined with a high number of balls ensures minimal variation in elastic deflection under load. This feature also contributes to significantly reduced frictional oscillations and a low friction force level, especially when external loads are applied. Designed to work with all SN/SNO ball guide rails from Bosch Rexroth, this runner block supports attachments that can be mounted both above and below it. Its design allows for long-term lubrication over several years, contributing to reduced maintenance needs. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWC-020-FNN-C0-H-2 (R169389310) offers exceptional precision and flexibility for linear motion applications where space is restricted upwards, and high torque load capacity is required without compromising on smooth operation or longevity.
