The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FLS-C2-X-1 (R165322820) is a high-precision ball runner block designed for linear motion applications requiring exceptional rigidity and accuracy. This runner block is part of the Ball Rail Systems product group and is characterized by its size, FLS format (flanged, long, standard height), and unalloyed steel CS construction. It features a medium preload (class C) and extra precision accuracy class (XP), ensuring smooth motion and high positioning accuracy. This model does not include a ball chain but comes with initial lubrication and preservation for reduced maintenance requirements. The roller bearing grease Dynalub enhances its performance longevity. The runner block body is in standard version with an overall length specified by the manufacturer. It offers interchangeability with guide rails of every accuracy level. Designed for demanding rigidity needs, this runner block significantly reduces frictional oscillations and maintains a low friction force level, even under external load conditions. Its excellent dynamic characteristics contribute to maximum precision in operation, while the patented entry zone can increase travel accuracy by up to six times. The B.RUNNER BLOCK CS KWD-025-FLS-C2-X-1 boasts long-term lubrication capabilities over several years, metal-threaded lube fittings on all sides, end-face fastening threads for various attachments, integrated all-around sealing for protection against contaminants, and high torque load capacity. Different preload classes are available to suit specific application requirements. With its design allowing use with just one runner block per rail if needed, it also includes two additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. The preloaded O-arrangement maximizes system rigidity, ensuring stable operation across various scenarios. Furthermore, this model can be used on all SN/SNO ball guide rails and maintains high load ratings in all four main directions of loading. Attachments can be mounted from both above and below the runner block. Optional features include an integrated inductive measuring system that is wear-free for precise feedback on positioning without physical contact.
