The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-SNH-C2-H-1 (R162172320) is a high-precision ball runner block designed for linear motion applications that require a slimline width, normal length, and high height. This runner block is manufactured from unalloyed steel CS and features an accuracy class H for high precision and a medium preload class C. It does not include a ball chain but comes with initial lubrication and preservation. With an innovative design that includes four rows of balls with point contact, this product offers reduced friction across all loading directions, leading to smoother motion and less heat generation compared to other systems. It's also equipped with standard seals to prevent contamination from dirt, chips, or coolants, which enhances its service life. The B.RUNNER BLOCK CS KWD-030-SNH-C2-H-1 offers excellent dynamic characteristics and rigidity in all load directions, allowing for use with just one runner block per rail if necessary. This model has been designed for interchangeability within the same accuracy class across all Bosch Rexroth Ball Rail Systems. Its patented entry zone increases travel accuracy by up to six times and can sustain high torque loads. The block's overall length is tailored for compatibility with various guide rail sizes and profiles. The runner block is prelubricated at the factory for convenience and supports long-term lubrication over several years. Endface fastening threads are provided for attachments, ensuring versatility in mounting options. The unit operates quietly due to the optimally designed ball return system and guideway. Furthermore, this model can withstand a range of ambient temperatures (specific min/max values should be consulted) and has been tested according to DIN ISO standards for dynamic load capacities and load moments. It offers different preload classes to suit various application requirements and can be used on all SN/SNO Ball Guide Rails from Bosch Rexroth.
