The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-X-1 (R16518382Y) is a ball runner block designed for linear motion applications requiring high precision and rigidity. This component is part of the Ball Rail Systems product group, and it is characterized by its size, steel CS construction, high preload, and extra precision accuracy class. The runner block body is made of unalloyed steel CS and features a high preload class C for increased rigidity and reduced frictional oscillations, especially under external load conditions. The B.RUNNER BLOCK CS KWD-020-FNS-C3-X-1 boasts an optimized entry zone geometry that enhances travel accuracy by up to six times compared to standard configurations. It includes a ball chain for quiet operation and optimal travel performance. The runner block is prelubricated with Roller bearing grease Dynalub, ensuring long-term lubrication over several years without the need for frequent maintenance. This model does not include attachment elements at the left or right front reference edges but does provide straight lube connection loosely attached. It also features an integrated all-around sealing system for protection against contaminants, ensuring durability in various environments. The design allows attachments to be mounted from both above and below the runner block, with endface fastening threads available for all attachments. The B.RUNNER BLOCK CS can be used on all SN/SNO ball guide rails and offers high load capacity in all four main loading directions due to its four-row ball configuration. Additional features include various sealing options such as standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper – each catering to different environmental conditions. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-X-1 provides maximum precision and rigidity for demanding linear motion applications while allowing for easy integration into existing systems with its interchangeable design compatible with various guide rails.
