The Bosch Rexroth B.RUNNER BLOCK CS KWC-025-SNN-C1-H-2 (R169421310) is a high-precision ball runner block designed for linear motion applications requiring compact size and high accuracy. This runner block features a slimline width, normal length, and low height profile (Format SNN), making it suitable for situations with restricted upward and longitudinal space. Its body is constructed from unalloyed steel CS, ensuring durability and robust performance. The B.RUNNER BLOCK CS offers low preload (Preload class C) and high accuracy (Accuracy class H), without the inclusion of a ball chain. It is preserved but comes without initial lubrication or attachment elements on the left or right front reference edges. The angular lube nipples are loosely attached, facilitating easy maintenance and long-term lubrication capabilities that can extend over several years. This model boasts an optimized entry zone geometry, increasing travel accuracy by up to six times while significantly reducing frictional oscillations and maintaining a low friction force level, especially under external loads. Its design allows for high torque load capacity and features integrated all-around sealing for protection against contaminants. The runner block can be interchanged with guide rails of varying accuracies, enhancing its versatility across different applications. Additional features include end-face fastening threads for various attachments and optional integration of an inductive, wear-free measuring system. The B.RUNNER BLOCK CS can be used on all SNS/SNO ball guide rails from Bosch Rexroth, providing self-alignment to compensate for misalignments without the need for a ball chain standard. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWC-025-SNN-C1-H-2 (R169421310) is a highly accurate and versatile component suitable for precision linear motion applications where space is limited and reliability over extended periods is essential.
