The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-U-1 (R16512192Y) is a ball runner block designed for precision and rigidity in linear motion systems. This component features a size 25 profile with an FNS format, indicating a flanged width, normal length, and standard height configuration. The runner block body is constructed from carbon steel (CS) for durability and is part of the Ball Rail System product group. This model has an ultra-precision accuracy class (UP) and a low preload class (C), ensuring smooth movement with minimal play. It includes a ball chain mechanism that contributes to reduced noise levels and optimal travel behavior. The runner block comes prelubricated with Roller bearing grease Dynalub, enhancing its maintenance-free operation over extended periods. An important aspect of the B.RUNNER BLOCK CS KWD-025-FNS-C1-U-1 is its interchangeability feature, which allows it to be combined with guide rails of every accuracy level. The design includes straight lube connections loosely attached for easy maintenance and all-around sealing for protection against contaminants. Additionally, the optimized entry zone geometry and high number of balls minimize variations in elastic deflection under load. For applications requiring high torque load capacity, this model offers an integrated solution with end-face fastening threads for attachments and additional mounting screw holes at the center of the block to improve rigidity under liftoff and side-loading conditions. An optional integrated inductive measuring system can also be added for wear-free position determination. The B.RUNNER BLOCK CS KWD-025-FNS-C1-U-1 is suitable for all SN/SNO ball guide rails and boasts high load ratings in all four main directions of loading. Its dynamic load capacity C and static longitudinal moment load capacity ML are determined based on a 100,000 m travel as per DIN ISO standards, ensuring reliability across various industrial applications where precision linear movement is critical.
