The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C2-P-1 (R16518222Z) is a high-precision ball runner block designed for linear motion applications requiring rigidity, precision, and durability. This runner block is part of the Ball Rail Systems product group and is characterized by its steel CS construction, medium preload class C, and precision accuracy class P. The B.RUNNER BLOCK CS KWD-020-FNS-C2-P-1 does not include a ball chain but comes with initial lubrication and preservation for immediate use. The product features a size FNS format, with a flanged width, normal length, and standard height. It boasts excellent dynamic characteristics such as reduced frictional oscillations and low friction levels under external loads. The patented entry zone significantly enhances travel accuracy by up to six times. The runner block's attachments can be mounted from both above and below; it also includes lube fittings with metal threads on all sides for easy maintenance. This model offers high torque load capacity across various preload classes and exceptional rigidity in all load directions, allowing for single runner block applications per rail when necessary. Additional mounting screw holes at the center of the block provide improved rigidity under liftoff and side-loading conditions. For applications demanding maximum system rigidity, this runner block employs a preloaded O-arrangement. An optional integrated inductive measuring system is available for wear-free operation. Factory prelubrication ensures long-term lubrication over several years without the need for frequent maintenance. The B.RUNNER BLOCK CS KWD-020-FNS-C2-P-1 can handle high load ratings in all four main loading directions and is compatible with all SN/SNO Ball Guide Rails from Bosch Rexroth. This ball runner block is designed to self-align for misalignment compensation without requiring self-alignment features. Its dynamic load capacity C and static torsional moment load capacity Mt are determined based on a 100 km travel as per DIN ISO standards. It is suitable for use in environments with temperatures ranging from -10°C to +100°C (short-term operation).
