The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C1-H-1 (R162121321) is a high-precision ball runner block designed for linear motion applications where space is limited, and high rigidity is required. This runner block features a slimline width, normal length, and high height format (SNH), made from unalloyed steel CS. It offers low preload (Preload class C) and high accuracy (Accuracy class H), ensuring maximum precision without the use of a ball chain. The product boasts an innovative design that significantly reduces frictional oscillations and maintains a low friction force level even under external load. The patented entry zone enhances travel accuracy by up to six times compared to standard systems. Its robust construction allows for high rigidity in all load directions, making it possible to use just one runner block per rail for certain applications while still achieving high torque load capacity. Interchangeability is a key feature of this model, as it can be combined with any ball guide rail system within the same accuracy class. Long-term lubrication capabilities extend over several years, reducing maintenance needs. The runner block comes prelubricated from the factory with Roller bearing grease Dynalub, promoting smooth and quiet operation. This model does not include attachment elements or a ball chain but does have straight lube connections loosely attached for ease of maintenance. It supports various seals such as standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper – all of which can be replaced during servicing to meet specific environmental requirements. With its dynamic characteristics and ability to withstand different preload classes, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C1-H-1 (R162121321) is suitable for applications demanding precision linear movement in restricted spaces with significant rigidity needs.
