The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C2-S-1 (R165112120) is a ball runner block designed for use in precision linear motion applications. This component is characterized by its super precision accuracy class SP and medium preload class C, which contribute to its high rigidity and excellent dynamic characteristics. The runner block body is constructed from unalloyed steel CS, ensuring durability and reliable performance. With an FNS format, the runner block has a flange width, normal length, and standard height. It does not include a ball chain but comes with initial lubrication and preservation for ease of use right out of the box. The roller bearing grease Dynalub enhances the longevity and smooth operation of the runner block. This model features a straight lube connection that is loosely attached, allowing for flexible maintenance options. The overall length of the runner block is specified in the product details, providing compatibility with various guide rail sizes. Notably, this runner block can be combined with guide rails of every accuracy level for versatile application across different systems. The B.RUNNER BLOCK CS KWD-015-FNS-C2-S-1 boasts several design advantages such as reduced frictional oscillations, low friction force levels under external load, and a patented entry zone that significantly increases travel accuracy. Additionally, it offers high torque load capacity, different preload classes, and high rigidity in all load directions—making it suitable for applications that require just one runner block per rail. For enhanced system rigidity and improved performance under liftoff and side loading conditions, this model includes two additional mounting screw holes at its center. An optional integrated inductive measuring system can be added for wear-free operation. The ball runner block's design also accommodates attachments from above or below and features lube fittings with metal threads on all sides for convenience. Overall, this Bosch Rexroth ball runner block is prelubricated at the factory for immediate use on all SN/SNO ball guide rails and supports long-term lubrication over several years without compromising on load ratings in any of the four main directions of loading.
