The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C3-U-1 (R165143922) is a high-precision ball runner block designed for linear motion applications requiring extreme accuracy and rigidity. The runner block body is constructed from unalloyed steel CS and features an ultra precision (UP) accuracy class with a high preload (class C) that ensures maximum precision. The FNS format indicates a flange width, normal length, and standard height, providing a versatile profile for various mounting scenarios. This ball runner block comes equipped with a ball chain to facilitate smooth travel behavior and low noise operation. It also includes initial lubrication and preservation, utilizing roller bearing grease Dynalub for longevity in operation. The product has been designed without attachment elements at the left or right front reference edge but includes straight lube connections that are loosely attached. The overall length of the runner block is specified in the product details, along with its height. It boasts interchangeability features, allowing it to be combined with guide rails of varying accuracy levels without compatibility issues. This unit is particularly suited for environments where high rigidity requirements are paramount, as it can significantly reduce frictional oscillations and maintain low friction levels even under external loads. Additional design considerations include optimized entry-zone geometry which minimizes variations in elastic deflection and two additional mounting screw holes at the center of the block to improve rigidity under liftoff and side loading conditions. For applications requiring integrated measurement systems, this model offers an optional inductive measuring system that is wear-free. The B.RUNNER BLOCK CS KWD-045-FNS-C3-U-1 is prelubricated from the factory for immediate use and supports long-term lubrication over several years. It can be utilized on all SN/SNO ball guide rails by Bosch Rexroth and maintains high load ratings in all main loading directions. Sealing options like SS standard seals, LS low-friction seals, DS double-lip seals, front seals, FKM seals, and cover plate wipers are available to cater to various environmental conditions ensuring protection against contaminants such as dirt or metal particles.
