The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-U-1 (R165181920) is a high-precision ball runner block designed for applications that demand maximum rigidity and accuracy. This component is part of Bosch Rexroth's Ball Rail Systems, specifically the B.RUNNER BLOCK series, and stands out with its ultra precision accuracy class UP and low preload class C. It is constructed from unalloyed steel CS for durability and reliability. This runner block boasts a size E profiled rail system with dimensions tailored to provide excellent dynamic characteristics, reduced frictional oscillations, and a low friction force level even under external load conditions. The absence of a ball chain in its design simplifies maintenance while maintaining performance. The ball runner block ensures high rigidity in all load directions, which allows for the use of just one runner block per rail in certain applications. The B.RUNNER BLOCK CS KWD-020-FNS-C1-U-1 features an overall length that supports interchangeability with guide rails across various accuracies. It comes prelubricated from the factory with roller bearing grease Dynalub, ensuring long-term lubrication potential over several years. Additionally, it has integrated all-around sealing to protect against contaminants and offers various sealing options such as standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper for different environmental conditions. With multiple lube fittings featuring metal threads on all sides and end-face fastening threads for attachments, this ball runner block provides flexibility in mounting accessories either from above or below. Its design includes two additional mounting screw holes at the center to improve rigidity under lift-off and side-loading conditions. This product also has the potential to integrate an optional inductive measuring system for wear-free operation. With its dynamic load capacity C and static torsional moment load capacity Mt backed by DIN ISO standards, the B.RUNNER BLOCK CS KWD-020-FNS-C1-U-1 is capable of handling high loads efficiently in all four main directions of loading.
