The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-N-1 (R165121423) is a high-precision ball runner block designed for linear motion applications requiring high rigidity and accuracy. This runner block features a steel CS body with size format FNS, which includes a width flange, normal length, and standard height. It is engineered to provide low preload (Preload class C) and standard accuracy (Accuracy class N), ensuring smooth motion with minimal frictional oscillations. Equipped with a ball chain, the B.RUNNER BLOCK CS ensures low noise levels and optimal travel behavior. The runner block's design includes straight lube connections that are loosely attached, facilitating easy maintenance. It comes prelubricated with Roller bearing grease Dynalub for initial operations and features integrated all-around sealing to protect against contaminants. This model boasts a high torque load capacity and allows attachments to be mounted from both above and below. The optimized entry-zone geometry alongside a large number of balls minimizes variation in elastic deflection, contributing to the unit's high precision. Additionally, the runner block's rigidity is enhanced under lift-off and side loading conditions due to two extra mounting screw holes at its center. The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-N-1 is compatible with all SN/SNO ball guide rails, providing flexibility in various application setups. It offers the same high load ratings in all four main loading directions and supports long-term lubrication over several years for sustained performance without frequent maintenance. Overall, this ball runner block is an ideal component for systems demanding maximum precision and rigidity, such as those found in automation equipment, machine tools, and other precision-guided machinery setups.
