The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FLS-C3-U-1 (R165323920) is a high-performance ball runner block designed for ultra-precise linear movement applications. This component boasts an FLS format, which indicates a flange width, long length, and standard height configuration. The runner block body is constructed from unalloyed steel CS, ensuring durability and robustness. It features a high preload class C and an accuracy class UP for ultra precision, catering to applications that demand the highest levels of accuracy and rigidity. This model does not include a ball chain but comes with initial lubrication and preservation for immediate use. The roller bearing grease Dynalub enhances the longevity and performance of the runner block. It has no attachment elements on either front reference edge but includes straight lube connections loosely attached for ease of maintenance. The overall length of the runner block is specified in the product details, ensuring compatibility with various guide rail lengths. With its interchangeable design, it can be combined with guide rails of every accuracy level. The B.RUNNER BLOCK CS KWD-025-FLS-C3-U-1 excels in reducing frictional oscillations and maintaining a low friction force level even under external loads. It supports excellent dynamic characteristics due to its patented entry zone which significantly increases travel accuracy. The product is designed for long-term lubrication over several years and features lube fittings with metal threads on all sides. Its integrated all-around sealing provides protection against contaminants while maintaining high torque load capacity. Different preload classes are available to suit various application requirements, and its high rigidity allows for use with just one runner block per rail in some cases. Enhanced system rigidity is achieved through a preloaded O-arrangement and additional mounting screw holes at the center of the runner block that improve stability under liftoff and side loading conditions. Optional features include an integrated, inductive, wear-free measuring system for precise tracking of movement. Attachments can be mounted from both above and below the runner block, offering flexibility in design integration. Suitable for use on all SN/SNO ball guide rails, this product maintains high load ratings in all four main loading directions after factory pre-lubrication. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FLS-C3-U-1 (R165323920) offers maximum precision with its ultra-high preload and accuracy standards, making it ideal for demanding applications where rigidity and precise linear motion are critical.
