The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-X-1 (R16518382Z) is a high-precision ball runner block designed for linear motion applications requiring exceptional accuracy and rigidity. It is characterized by its size, FNS format (flange width, normal length, standard height), and construction from unalloyed steel CS. The runner block boasts a high preload class C and extra precision accuracy class XP, ensuring maximum precision without the inclusion of a ball chain. This product has an overall length of . mm and can be combined with guide rails of every accuracy level to meet various application needs. It is tailored for situations demanding high rigidity, with dynamic characteristics that include significantly reduced frictional oscillations and a low friction force level, especially under external loads. The patented entry zone amplifies travel accuracy by up to six times. The B.RUNNER BLOCK CS KWD-020-FNS-C3-X-1 features attachments that can be mounted from both above and below, metal-threaded lube fittings on all sides, end-face fastening threads for attachments, and integrated all-around sealing. Its design allows for high torque load capacity across different preload classes and maintains high rigidity in all load directions. This enables the use of just one runner block per rail in certain applications. With additional mounting screw holes at the center for enhanced rigidity under liftoff and side loading conditions, this ball runner block also supports maximum system rigidity through preloaded O-arrangement. An optional integrated inductive measuring system adds to its versatility without wear concerns. Pre-lubricated at the factory for immediate use on all SN/SNO ball guide rails, this runner block is engineered for long-term lubrication over several years while maintaining consistent load ratings in all four main loading directions. Its design ensures reliability even in challenging environments with permissible ambient temperatures ranging from min ... max °C (for short durations).
