The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C2-U-1 (R165142920) is a high-precision ball runner block designed for linear motion applications requiring rigidity, accuracy, and durability. This runner block is part of the company's Ball Rail Systems and is characterized by its steel CS construction, medium preload class C, and ultra precision accuracy class UP. It does not incorporate a ball chain but comes with initial lubrication and preservation. This model has an overall length of . mm and is notable for its ability to provide maximum precision due to a patented entry zone that increases travel accuracy up to six times. It is designed without attachment elements on the left or right front reference edges but includes a straight lube connection that is loosely attached. The B.RUNNER BLOCK CS can be used interchangeably with guide rails of every accuracy level, making it versatile for various configurations. The product boasts excellent dynamic characteristics, reduced frictional oscillations, and low friction levels even under external loads. Its design allows attachments to be mounted from both above and below the block, while lube fittings with metal threads are accessible on all sides. The end-face fastening thread accommodates all attachments seamlessly. Moreover, this runner block features integrated all-around sealing and high torque load capacity. Its rigidity in all load directions allows for single-runner block applications 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 measuring system offers wear-free operation if required. Pre-lubrication at the factory ensures long-term maintenance-free performance over several years. The B.RUNNER BLOCK CS can handle high load ratings in all four main loading directions and is compatible with SNSSNO ball guide rails. In terms of environmental adaptability, it can operate within a wide temperature range (min ... max °C), although consultation is advised for use in negative temperatures. The dynamic load capacity C and other specifications adhere to DIN ISO standards for reliability assurance in demanding applications.
