The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C1-X-1 (R165131821) is a high-precision ball runner block designed for linear motion systems requiring exceptional rigidity and dynamic characteristics. This component is part of the Ball Rail Systems product group and is crafted from unalloyed steel CS, ensuring durability and consistent performance. The runner block features a size FNS format, which denotes its width, length, and height as flange, normal, and standard respectively. It boasts an extra precision accuracy class (XP) and a low preload class (C), tailored for applications that demand maximum precision. This model is devoid of a ball chain but comes with initial lubrication and preservation for ease of use right out of the box. It utilizes Roller bearing grease Dynalub 510 to maintain smooth operation. The runner block body's standard version has an overall length specified in the product details. Its interchangeability with guide rails across all accuracy levels makes it versatile for various configurations. The B.RUNNER BLOCK CS KWD-035-FNS-C1-X-1 excels in environments where high rigidity is crucial due to its excellent dynamic properties, significantly reduced frictional oscillations, and low friction force level even under external load. Its patented entry zone can improve travel accuracy by up to six times. Additionally, attachments can be mounted from both above and below the runner block, which also includes lube fittings with metal threads on all sides. Moreover, this model offers high torque capacity across different preload classes and maintains high rigidity in all load directions—allowing for the possibility of using just one runner block per rail in certain applications. The design includes two additional mounting screw holes at the center for enhanced rigidity under lift-off and side-loading conditions. For systems requiring long-term reliability, this ball runner block's prelubrication enables several years of maintenance-free operation. It also has integrated all-around sealing to protect against contaminants and ensure longevity. An optional integrated inductive measuring system can be added for wear-free operation if precise measurements are needed within the application. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C1-X-1 (R165131821) stands out with its robust construction, exceptional precision capabilities, versatility in use with various rail accuracies, long-term lubrication options, and comprehensive sealing solutions—all contributing to its suitability for demanding linear motion applications.
