The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C1-U-1 (R165111920) is a ball runner block designed for ultra-precise linear motion applications. It features a steel CS runner block body and is part of the FNS series, indicating its flange width, normal length, and standard height. The runner block is classified under the low preload class C and ultra precision accuracy class UP. It does not come with a ball chain but includes initial lubrication and preservation. This product boasts an innovative design that allows for high rigidity requirements and excellent dynamic characteristics, with significantly reduced frictional oscillations and low friction force levels, particularly under external loads. The patented entry zone increases travel accuracy by up to six times. Attachments can be mounted from both above and below the runner block, which also features lube fittings with metal threads on all sides and end-face fastening threads for all attachments. The Bosch Rexroth B.RUNNER BLOCK CS offers an integrated all-around sealing system, high torque load capacity, various preload classes, and impressive rigidity in all loading directions. This allows for applications using just one runner block per rail. Enhanced rigidity under lift-off and side loading conditions is achieved through additional mounting screw holes at the center of the runner block. An optional integrated, inductive, wear-free measuring system can be included with this model. Pre-lubricated at the factory, it's compatible with all SN/SNO ball guide rails from Bosch Rexroth. Long-term lubrication over several years is possible due to its design. The product maintains high load ratings in all four main directions of loading. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C1-U-1 (R165111920) offers maximum system rigidity due to its preloaded O-arrangement and is engineered to meet demanding precision requirements in various linear motion applications.
