The Bosch Rexroth R166421310 (type KWC-025-SKN-C1-H-2) is a genuine linear guide component with size 25, SKN slimline, short, low height, preload C1, accuracy H. RendatSP supplies it new and original, ready to ship worldwide.
Rexroth profiled rail systems (ball and roller runner blocks) give machine tools, automation axes and handling systems their precision and rigidity. Runner blocks must match the rail size, preload class and accuracy class exactly, so ordering by the Rexroth material number is the safest way to restore the original axis performance.
