The Rexroth KWD-035-FNS-C1-H-1 (material no. R165131321) is a genuine Bosch Rexroth ball runner block: ball runner block, FNS, size 35, steel CS, accuracy high, low preload, without ball chain.<\/p>\n
A runner block replaces a worn or damaged carriage on a machine axis; matching size, length, preload and accuracy keeps the axis behaviour the same.<\/p>\n
