The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C1-X-1 (R16514182Y) is a premium ball runner block designed for linear motion applications requiring high precision and rigidity. This runner block features a size 45 flange width, normal length, and standard height, made from unalloyed steel CS. It is characterized by its low preload (class C) and extra precision accuracy class (XP), ensuring minimal variation in elastic deflection and maximum travel accuracy. The product is equipped with a ball chain that contributes to its low noise operation and optimal travel behavior. The runner block body comes with initial lubrication and preservation, using roller bearing grease Dynalub for longevity. Notably, the ball runner block has no attachment elements on either front reference edge but includes straight lube connections that are loosely attached. Its design boasts an optimized entry zone geometry with a high number of balls, significantly reducing frictional oscillations and maintaining a low friction force level even under external load. This allows for applications that require just one runner block per rail while maintaining high rigidity in all load directions. The system's rigidity is further enhanced by additional mounting screw holes at the center of the runner block. For maintenance convenience, the unit features lube fittings with metal threads on all sides and an end-face fastening thread for attachments. The integrated all-around sealing offers protection against contaminants, contributing to the long-term lubrication capabilities that can extend over several years. This Bosch Rexroth runner block can be used on all SN/SNO ball guide rails and maintains consistent high load ratings in all four main loading directions. It's prelubricated at the factory for immediate use upon installation. With its robust construction and advanced design features, this ball runner block is ideal for applications demanding utmost precision and durability.
