The Bosch Rexroth B.RUNNER BLOCK HS KWD-015-SLS-C2-H-1 (R201212390) is a high-speed ball runner block designed for linear motion applications that require precision and speed. This runner block is part of the SLS series, featuring a slimline width, long length, and standard height. It is constructed from carbon steel CS, ensuring durability and strength. The preload class C indicates a medium preload for optimal performance balance between rigidity and movement. With an accuracy class H, this runner block offers high precision for demanding tasks. The B.RUNNER BLOCK HS KWD-015-SLS-C2-H-1 does not include a ball chain but comes with initial lubrication and preservation to reduce maintenance needs. It utilizes Roller bearing grease Dynalub to enhance performance over time. The runner block body is in the standard version with an overall length of . mm. Its design allows for interchangeability with other guide rails within the same accuracy class, providing flexibility in system configuration. This model boasts features that support maximum speeds while ensuring low frictional oscillations and minimal friction force levels, even under external loads. Its patented entry zone significantly improves travel accuracy by up to six times compared to conventional designs. The block also allows attachments to be mounted from above and includes lube fittings with metal threads on all sides for easy maintenance. With electrically insulating properties due to ceramic balls, it offers excellent dynamic characteristics and system rigidity due to its preloaded O-arrangement. The B.RUNNER BLOCK HS KWD-015-SLS-C2-H-1 supports minimum quantity lubrication with an integrated reservoir for oil lubrication, enabling long-term lubrication over several years without frequent service interventions. It can withstand high load ratings in all four main loading directions and is compatible with all SN/SNO ball guide rails. Pre-lubricated at the factory, it comes in various sizes to accommodate different system requirements while maintaining consistent performance across temperature ranges from min ... max °C (admissible for short time).
