The Bosch Rexroth B.RUNNER BLOCK CS KWC-025-SKN-C0-N-2 (R166429410) is a ball runner block designed for high precision linear movement in restricted spaces. This component is part of the Ball Rail Systems product line, offering a slimline, short, and low format (SKN) for compact applications. The runner block body is constructed from unalloyed steel CS and is preserved without initial lubrication or attachment elements on the front reference edges. It features angular lube nipples loosely attached for convenience. With an accuracy class N signifying standard precision and a preload class C indicating preload-free operation, this runner block ensures smooth motion without pre-tension. The B.RUNNER BLOCK CS is notable for its patented entry zone, which enhances travel accuracy by up to six times while significantly reducing frictional oscillations and maintaining a low friction force level, especially when under external load. Long-term lubrication capabilities extend over several years due to its design. This model does not include a ball chain but boasts an all-around sealing system that can be used with all SN/SNO ball guide rails. The optimized entry zone geometry coupled with a high number of balls reduces variation in elastic deflection, ensuring consistent performance. In terms of technical specifications, the overall length of the runner block is specified by Bosch Rexroth standards. The B.RUNNER BLOCK CS can handle dynamic load capacities and load moments as per DIN ISO standards with adjustments provided for different travel lengths. Its design accommodates self-alignment to compensate for misalignments and features multiple seal options including standard SS seals and optional LS (low-friction), DS (double-lip), FKM seals, or cover plate wipers for varying environmental conditions. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWC-025-SKN-C0-N-2 (R166429410) provides precise linear guidance with low friction in compact spaces while offering flexibility through interchangeable components and long-term maintenance options.
