The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C3-U-1 (R165133920) is a high-precision ball runner block designed for linear motion applications requiring exceptional rigidity and accuracy. This model features a size FNS format, with a width flange, normal length, and standard height, constructed from unalloyed steel CS. It boasts an ultra precision accuracy class UP and a high preload class C, ensuring maximum precision and reduced frictional oscillations even under external load conditions. The runner block body is of the standard version with an overall length of . mm and does not include a ball chain. It comes prelubricated with Dynalub grease for initial use and preservation, enhancing its long-term performance capabilities. The product is distinguished by its ability to offer excellent dynamic characteristics, such as significantly reduced friction forces and enhanced travel accuracy—up to six times due to its patented entry zone. This model provides versatile mounting options since attachments can be installed from both above and below the runner block. Lube fittings with metal threads are accessible on all sides for easy maintenance, while the endface fastening thread accommodates all attachments securely. The integrated all-around sealing contributes to the product's durability by protecting against contaminants. The B.RUNNER BLOCK CS KWD-035-FNS-C3-U-1 is compatible with SN/SNO ball guide rails and supports long-term lubrication over several years without the need for frequent maintenance. It offers high load ratings in all four main loading directions due to its robust design. Two additional mounting screw holes at the center of the runner block enhance rigidity under liftoff and side loading conditions. In summary, this Bosch Rexroth ball runner block is tailored for applications that demand maximum system rigidity, high torque load capacity across various preload classes, and consistent performance in diverse operating environments within permissible ambient temperatures ranging from min ... max °C (short time admissible).
