The Bosch Rexroth B.RUNNER BLOCK HS KWD-025-SLS-C2-H-1 (R201222390) is a high-speed ball runner block designed for linear motion applications requiring precision and speed. This component is part of the company's linear guide technology offerings and is characterized by its slimline width, long length, and standard height, which make it an ideal choice for space-sensitive installations. The runner block body is constructed from carbon steel CS to ensure durability and longevity. Featuring a medium preload class C and a high accuracy class H, this model does not include a ball chain but comes with initial lubrication and preservation to facilitate immediate use upon installation. It utilizes roller bearing grease Dynalub for reduced friction and smooth operation. The B.RUNNER BLOCK HS KWD-025-SLS-C2-H-1 is designed without attachment elements on its left or right front reference edges, allowing for versatile mounting options. This runner block can achieve very high travel speeds due to its design, which also minimizes frictional oscillations and maintains low friction levels even under external load conditions. Its patented entry zone significantly improves travel accuracy by up to six times compared to standard blocks. It features lube fittings with metal threads on all sides for easy maintenance and offers maximum system rigidity through its preloaded O-arrangement. The unit boasts excellent dynamic characteristics, including the ability to support high load ratings in all four main directions of loading. It's compatible with all SN/SNO ball guide rails, ensuring limitless interchangeability within each accuracy class. Furthermore, the B.RUNNER BLOCK HS KWD-025-SLS-C2-H-1 supports minimum quantity lubrication with an integrated reservoir for oil lubrication, allowing for long-term maintenance-free operation. Overall, this Bosch Rexroth runner block stands out for its ability to accommodate misalignments without self-alignment features while maintaining precision in demanding linear motion applications.
