The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNS-C1-N-1 (R162221421) is a highly precise ball runner block designed for linear motion applications. It features a slimline width, normal length, and standard height format (SNS), providing an optimal solution for restricted spaces in the transverse direction. The runner block body is constructed from unalloyed steel CS and comes with a low preload of class C and a standard accuracy class N, ensuring reliable performance without the need for a ball chain. The product boasts an overall length of . mm and offers limitless interchangeability within each accuracy class, allowing it to be combined with various guide rails. This versatility is matched by high torque load capacity, consistent load ratings in all four main directions, and the possibility of long-term lubrication over several years. The optimized entry-zone geometry coupled with a high number of balls reduces elastic deflection variation. Additional features include attachments that can be mounted from above, integrated all-around sealing to protect against contaminants, and a minimum quantity lubrication system with an oil reservoir for reduced maintenance. The runner block also includes end-face fastening threads for various attachments and can be used on all SNS/SNO ball guide rails. Dynamic characteristics are excellent due to the pre-lubrication at the factory, ensuring smooth motion right out of the box. The permissible ambient temperature ranges from min ... max °C (admissible for short periods), while the dynamic load capacity C is determined based on a 100 km travel as per DIN ISO standards. In terms of design, this ball runner block offers self-aligning capabilities to compensate for misalignments without self-alignment features. It has been designed to minimize friction coefficients between . and . while providing robust sealing options such as standard seal SS, low-friction seal LS, double-lip seal DS, front seal options, FKM seals for extreme environments, and cover plate wipers for coarse dirt or chips protection. Overall, this Bosch Rexroth ball runner block provides exceptional precision and flexibility in linear motion applications across various industries due to its robust design and comprehensive feature set.
