KWD-025-SNS-C1 ball runner blocks and guide rails

This is a runner block from Rexroth’s ball rail system in size 25. A ball rail system pairs a profiled steel rail with a carriage on recirculating balls, giving low-friction motion with high rigidity and load capacity in all load directions. The code reads as a standard-width, normal-height block (SNS) with a C1 preload class, which is a low-play fit for general machine use. The block has integrated seals and lubrication ports, and rails are screwed down from above and can be joined for long strokes. Typical uses are machine tools, handling, packaging and semiconductor machinery.
