The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-U-1 (R16518392Z) is a ball runner block designed for ultra-precision linear motion applications, offering high rigidity and dynamic characteristics. This specific model is part of the FNS series, indicating a flange width, normal length, and standard height. The runner block body is crafted from unalloyed steel CS and features a high preload class C and an accuracy class UP for ultra-precision movement. The B.RUNNER BLOCK CS KWD-020-FNS-C3-U-1 is devoid of a ball chain but comes with initial lubrication and preservation, ensuring reduced frictional oscillations and low friction levels, especially under external loads. The patented entry zone significantly enhances travel accuracy by up to six times. It boasts an integrated all-around sealing system and offers various attachment possibilities from both above and below the runner block. Additionally, it has lube fittings with metal threads on all sides and end-face fastening threads for attachments. With its high torque load capacity and multiple preload classes available, this runner block can accommodate applications requiring just one runner block per rail while still maintaining high rigidity in all load directions. The design includes additional mounting screw holes at the center to improve rigidity under liftoff and side loading conditions. For systems requiring maximum precision, there's an optional integrated inductive measuring system. Pre-lubricated at the factory for convenience, this Bosch Rexroth ball runner block can be used on all SN/SNO ball guide rails. It supports long-term lubrication over several years without the need for maintenance. Designed to handle high load ratings in all four main directions of loading, it ensures reliability across various applications. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-U-1 (R16518392Z) stands out for its ultra-precision accuracy class UP, robust construction suitable for demanding linear motion tasks with an emphasis on longevity and maintenance-free operation within specified temperature ranges.
