The Bosch Rexroth B.RUNNER BLOCK NR KWD-020-FLS-C0-H-1 (R200289330) is a high-precision, corrosion-resistant ball runner block designed for the most demanding rigidity requirements and maximum precision. This runner block is made from Resist NR steel, complying with DIN EN standards, ensuring excellent durability and resistance to rust. It features a size 20 profile with an FLS format that includes a wide flange, long length, and standard height for versatile applications. With an accuracy class of H for high precision and preload class C for being preload-free, this runner block offers smooth motion and reduced frictional oscillations, especially under external loads. The product does not include a ball chain but comes with initial lubrication using Roller bearing grease Dynalub 510 for extended service life without frequent maintenance needs. The overall length of the runner block is meticulously designed to ensure compatibility across various guide rails. The ball runner block also boasts improved rigidity due to the additional mounting screw holes at its center, enhancing performance under side loading conditions. It has the capability to handle high torque loads efficiently and maintains high load ratings in all four main directions of loading. The dynamic characteristics of this runner block are exemplary, allowing it to be used on all SNS/SNO ball guide rails offered by Rexroth. Furthermore, this model allows attachments to be mounted from both above and below the runner block, providing flexibility during installation. The interchangeability feature of this product stands out as it can be combined with all ball guide rail systems within each accuracy class without limitations. The B.RUNNER BLOCK NR KWD-020-FLS-C0-H-1 is prelubricated at the factory, promoting long-term lubrication over several years while offering excellent dynamic characteristics throughout its operation.
