The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-P-1 (R165121222) is a high-precision ball runner block designed for linear motion applications requiring rigidity and accuracy. This model features a steel CS runner block body with a low preload (preload class C) and precision accuracy (accuracy class P). It comes equipped with a ball chain, ensuring low noise levels and optimal travel behavior. The runner block is prelubricated with roller bearing grease Dynalub for immediate use and has provisions for long-term lubrication over several years. The B.RUNNER BLOCK CS KWD-025-FNS-C1-P-1 is characterized by its FNS format, indicating a flange width, normal length, and standard height. Its straight lube connection is loosely attached, allowing for easy maintenance. The product boasts an integrated all-around sealing system to protect against contaminants, enhancing its durability and service life. This model does not include attachment elements at the left or right front reference edges but does offer end-face fastening threads for versatile mounting options. The optimized entry-zone geometry paired with a high number of balls reduces elastic deflection variability, contributing to the unit's high rigidity in all load directions. This allows for the possibility of using just one runner block per rail in certain applications. Furthermore, the B.RUNNER BLOCK CS KWD-025-FNS-C1-P-1 offers high torque load capacity and can accommodate different preload classes to suit specific application needs. For enhanced precision, an optional integrated, inductive, and wear-free measuring system can be included. The ball runner block is interchangeable with guide rails across every accuracy level, ensuring flexibility in use. With its robust construction and advanced features such as additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions, this Bosch Rexroth ball runner block is suitable for applications demanding maximum precision and system rigidity. It is compatible with all SNSSNO ball guide rails and maintains consistent high load ratings in all four main loading directions.
