The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-SLS-C3-X-1 (R162383820) is a high-precision ball runner block designed for linear motion applications requiring extra precision and high preload. This runner block is part of the ball rail systems, offering a slimline width, long length, and standard height format (SLS). It is constructed from unalloyed steel CS and features an accuracy class XP for extra precision. The product boasts a high preload class C without a ball chain, ensuring robust performance and reduced elastic deflection. The B.RUNNER BLOCK CS KWD-020-SLS-C3-X-1 has an optimized entry-zone geometry and a significant number of balls to provide excellent dynamic characteristics while maintaining consistent performance under varying loads. It allows for easy attachment from above with its end-face fastening thread and incorporates integrated all-round sealing to protect against contaminants. The product also includes a minimum quantity lubrication system with an oil reservoir to facilitate long-term lubrication over several years. This model has been designed to accommodate very high loads and offers the same load ratings in all four main loading directions. It provides interchangeability within each accuracy class, allowing it to be combined with all SN/SNO ball guide rails. The runner block's dynamic load capacity C and dynamic torsional moment load capacity Mt are determined according to DIN ISO standards, ensuring reliable performance even under demanding conditions. Furthermore, the B.RUNNER BLOCK CS KWD-020-SLS-C3-X-1 is equipped with various sealing options such as the standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper—each tailored for different environmental conditions ranging from fine dirt to coarse chips. In summary, this Bosch Rexroth ball runner block is engineered for applications where space is limited in the transverse direction but requires precise movement control, high loads tolerance, minimal frictional resistance, and versatility in combining with different guide rails within its accuracy class.
