The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-H-1 (R165122322) is a high-precision ball runner block designed for linear motion applications requiring high rigidity and precision. This runner block features a size 25 profile, FNS format indicating a flange width, normal length, and standard height. Constructed from unalloyed steel CS, it offers medium preload (class C) and high accuracy (class H), ensuring reliable performance under demanding conditions. Equipped with a ball chain, the B.RUNNER BLOCK CS reduces noise and enhances travel behavior. It comes prelubricated with roller bearing grease Dynalub for initial use and long-term lubrication possibilities. The block's body has an overall length of . mm and is interchangeable with guide rails of every accuracy class. The product excels in applications where reduced frictional oscillations and low friction force levels are crucial, particularly when external loads are applied. Its patented entry zone improves travel accuracy up to six times, making it suitable for tasks that demand maximum precision. Additionally, the runner block boasts an integrated all-around sealing system to protect against contaminants, ensuring longevity and consistent operation. The optimized entry zone geometry alongside the high number of balls minimizes variation in elastic deflection while maintaining high rigidity in all load directions. This model also features additional mounting screw holes at its center to enhance rigidity under side loading conditions or when lift-off occurs. It can be mounted from above or below with endface fastening threads for attachments without the need for left or right front reference edges. The B.RUNNER BLOCK CS can be used on all SNSSNO ball guide rails by Bosch Rexroth and supports high torque loads due to its preloaded O-arrangement design. An optional integrated inductive measuring system provides wear-free operation. With its robust design and versatile features, this runner block is engineered to meet the requirements of various linear motion systems across numerous applications.
