The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FNS-C1-H-1 (R165171321) is a high-precision ball runner block designed for linear motion applications requiring high rigidity, excellent dynamic characteristics, and maximum precision. The runner block body is constructed from unalloyed steel CS and features a size FNS format with standard width, normal length, and standard height. It offers a low preload in class C and high accuracy in class H. This model does not include a ball chain but comes with initial lubrication and preservation using roller bearing grease Dynalub. It also boasts an overall length of . mm and can be combined with guide rails of every accuracy level for increased versatility. The product is distinguished by its ability to significantly reduce frictional oscillations and maintain a low friction force level, especially under external loads. The B.RUNNER BLOCK CS KWD-030-FNS-C1-H-1 offers several key benefits such as a patented entry zone that enhances travel accuracy by up to six times, all-around sealing for protection against contaminants, high torque load capacity, various preload classes, and the option for an integrated inductive measuring system. Its design allows attachments to be mounted from both above and below the runner block while providing lube fittings with metal threads on all sides. It is prelubricated at the factory for immediate use on SNSSNO ball guide rails and supports long-term lubrication over several years without the need for maintenance. The product can sustain high load ratings in all four main loading directions due to its robust construction. Additionally, it has been engineered to improve rigidity under liftoff and side loading conditions with extra mounting screw holes at its center. In summary, this Bosch Rexroth ball runner block is suitable for applications demanding utmost precision and durability while offering flexibility in design integration and maintenance-free operation over extended periods.
