The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-U-1 (R165122920) is a high-precision ball runner block designed for linear motion applications requiring extreme accuracy and rigidity. This component, part of the Ball Rail Systems product group, is crafted from unalloyed steel CS and offers an ultra precision accuracy class UP. The runner block is characterized by a medium preload class C and does not include a ball chain. This runner block boasts an innovative design with four rows of balls that allow for point contact in all loading directions, significantly reducing friction and heat generation. It comes prelubricated with Roller bearing grease Dynalub, ensuring long-term lubrication over several years. The B.RUNNER BLOCK CS is also equipped with integrated all-around sealing to prevent contamination from external particles like dirt or metal shavings, enhancing its service life. The product features multiple attachments points on the top and bottom, metal-threaded lube fittings on all sides, and end-face fastening threads for various attachments. Its design allows for high torque load capacity and can accommodate applications with just one runner block per rail due to its high rigidity in all load directions. Additionally, it includes two extra mounting screw holes at the center for improved rigidity under lift-off and side loading conditions. It's also noteworthy that this model provides interchangeability with guide rails of every accuracy level within the system. The optional integrated, inductive measuring system offers a wear-free solution for precise position detection. Rated highly in terms of dynamic characteristics such as reduced frictional oscillations and low friction force levels, especially under external loads, this runner block ensures maximum precision in operation. Designed to work seamlessly on all SN/SNO ball guide rails, the B.RUNNER BLOCK CS KWD-025-FNS-C2-U-1 is suited for applications demanding maximum system rigidity and performance where ambient temperatures range from minimum permissible levels up to short periods at higher temperatures as specified by Bosch Rexroth standards.
