The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-U-1 (R165183922) is a high precision ball runner block designed for linear motion applications requiring extreme accuracy and rigidity. This model features a size 20 flange width with normal length and standard height, constructed from unalloyed steel CS for durability. It is classified under the high preload class C and ultra precision accuracy class UP, ensuring minimal elastic deflection and enhanced travel accuracy. Equipped with a ball chain, this runner block facilitates low noise operation and optimal travel behavior. The unit comes prelubricated with roller bearing grease Dynalub, ensuring long-term lubrication over several years without the need for frequent maintenance. The straight lube connection is loosely attached for convenience. The innovative design includes an integrated all-around sealing system to protect against contaminants, increasing the service life of the runner block. For applications demanding high torque capacity, this model boasts an optimized entry zone geometry that increases travel accuracy by up to six times compared to standard blocks. The B.RUNNER BLOCK CS can be used on all SNS/SNO ball guide rails and supports a wide range of attachments that can be mounted from both above and below. The dynamic load capacity C and static longitudinal moment load capacity ML indicate robust performance in various loading conditions. The product also offers flexibility in terms of interchangeability with guide rails across different accuracies. This Bosch Rexroth runner block is ideal for applications where reduced frictional oscillations are crucial, such as in machine tools or automation systems where precision movement is key. The additional mounting screw holes at the center enhance rigidity under side loading conditions, while the optional integrated measuring system provides wear-free operation for accurate positioning tasks.
