The Bosch Rexroth B.RUNNER BLOCK HS KWD-020-SLS-C2-H-1 (R201282390) is a high-speed ball runner block designed for linear motion applications requiring precision and speed. This runner block is part of the ball rail system, featuring a slimline width, long length, and standard height format (SLS). It is constructed from carbon steel CS, ensuring durability and strength. The product has been engineered with a medium preload (class C) and high accuracy (class H), without the inclusion of a ball chain. This runner block boasts an initial lubrication and preservation for reduced maintenance needs, utilizing Roller bearing grease Dynalub to maintain smooth operation. Notably absent are attachment elements on both front reference edges, with a straight lube connection loosely attached for ease of maintenance. The runner block body comes in a standard version with an overall length specified by the manufacturer. The B.RUNNER BLOCK HS KWD-020-SLS-C2-H-1 excels in areas demanding maximum speeds, thanks to its design which minimizes frictional oscillations and maintains low friction levels even under external loads. The patented entry zone significantly enhances travel accuracy by up to six times. Attachments can be mounted from above for convenience, while lube fittings feature metal threads on all sides for versatility. This product offers maximum system rigidity through its preloaded O-arrangement and features electrically insulating properties due to the use of ceramic balls. Its dynamic characteristics are excellent, providing smooth and quiet operation alongside optimal ball return and guideway design. Additionally, it supports minimum quantity lubrication with an integrated reservoir for oil lubrication. With high load ratings in all four main directions of loading, this runner block can be utilized on all SN/SNO ball guide rails. It arrives pre-lubricated from the factory and is available in eight common sizes. Interchangeability is limitless within each accuracy class across all ball guide rail systems and ball runner block versions. It's designed to offer long-term lubrication over several years while also allowing self-alignment to compensate for any misalignments during installation or use.
