The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C1-N-1 (R162121420) is a state-of-the-art ball runner block designed for linear motion applications where space is limited in the transverse direction, and high rigidity is required. This runner block boasts a slimline width, normal length, and high height format (SNH), constructed from unalloyed steel CS for durability. It features low preload (Preload class C) and standard accuracy (Accuracy class N), ensuring smooth motion without a ball chain. The B.RUNNER BLOCK CS is pre-lubricated with Roller bearing grease Dynalub to provide long-term lubrication over several years, reducing maintenance requirements. It has an overall length of . mm and offers exceptional rigidity compared to the SNS model, allowing for single runner block use per rail without compromising stability or performance. Designed with a patented entry zone, it significantly increases travel accuracy by up to six times while maintaining low frictional oscillations and reduced friction force levels, especially under external loads. The ball return and guideway are optimized for smooth and quiet operation. This runner block can be interchangeably combined with any guide rails within the same accuracy class due to its limitless interchangeability feature. It also has an excellent dynamic load capacity C and can handle high torque loads efficiently. The product is ideal for various dynamic applications due to its outstanding dynamic characteristics. Additional features include end-face fastening threads for attachments, multiple seal options such as standard SS seals, LS low-friction seals, DS double-lip seals, FKM seals for extreme environments, and cover plate wipers for coarse dirt conditions—all interchangeable during servicing. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C1-N-1 (R162121420) offers high precision and rigidity suitable for demanding linear motion applications where space constraints are present. Its durable construction, low maintenance needs due to pre-lubrication, and ability to withstand various environmental conditions make it a versatile choice in the field of linear guide technology.
