The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-H-1 (R165121322) is a high-precision ball runner block designed for linear motion applications requiring high rigidity and accuracy. This model features a steel CS runner block body, with size and format FNS indicating a flange width, normal length, and standard height. It is engineered for low preload (Preload class C) and high accuracy (Accuracy class H), ensuring smooth motion with minimal elastic deflection. Equipped with a ball chain, the B.RUNNER BLOCK CS KWD-025-FNS-C1-H-1 reduces noise levels and enhances travel behavior. The product comes prelubricated with roller bearing grease Dynalub, facilitating long-term lubrication over several years without the need for frequent maintenance. Its optimized entry zone geometry and a high number of balls contribute to the runner block's ability to maintain consistent travel accuracy under various load conditions. The design includes integrated all-around sealing to protect against contaminants, while the endface fastening thread allows for easy attachment of accessories from both above and below the runner block. Two additional mounting screw holes at the center enhance rigidity, especially under side loading conditions. This ball runner block can be used with all SN/SNO ball guide rails offered by Bosch Rexroth, providing compatibility across different systems. Its O-arrangement offers maximum system rigidity due to its preloaded configuration. Furthermore, it is capable of handling high torque loads and offers various preload classes to suit different application needs. An optional feature includes an integrated inductive measuring system that is wear-free for precise positioning tasks. With its dynamic load capacity C and static longitudinal moment load capacity ML, this runner block maintains high load ratings in all four main loading directions, making it suitable for diverse industrial applications where precision linear movement is critical.
