The Bosch Rexroth B.RUNNER BLOCK HS KWD-030-SLS-C2-H-1 (R201272390) is a high-speed ball runner block designed for applications requiring precision and speed. This runner block is part of the linear motion technology product line, featuring a slimline width, long length, and standard height format designated as SLS. The body of the runner block is constructed from carbon steel CS, ensuring durability and robustness in operation. With a preload class C indicating medium preload and an accuracy class H for high precision, this model is engineered to facilitate very high travel speeds while maintaining accurate movement. The absence of a ball chain contributes to its streamlined design. It comes with initial lubrication and preservation, utilizing Roller bearing grease Dynalub to reduce maintenance requirements. The B.RUNNER BLOCK HS is notable for its ability to significantly reduce frictional oscillations and maintain low friction force levels even under external loads. Its patented entry zone optimizes travel accuracy by up to six times compared to standard systems. The design allows for attachments to be mounted from above, and it features lube fittings with metal threads on all sides for ease of maintenance. This model boasts maximum system rigidity due to its preloaded O-arrangement and offers excellent dynamic characteristics. It provides electrical insulation through the use of ceramic balls and supports limitless interchangeability within each accuracy class. Designed for smooth, quiet operation, it also includes an end-face fastening thread for all attachments. The B.RUNNER BLOCK HS ensures long-term lubrication over several years without the need for frequent re-lubrication thanks to an integrated reservoir for oil lubrication. It can handle high load ratings in all four main loading directions and is compatible with all SN/SNO ball guide rails. Pre-lubricated at the factory, this runner block is available in eight common sizes, accommodating a wide range of application needs while supporting maximum permissible linear speeds and accelerations within specified temperature ranges as per DIN ISO standards.
