The Rexroth KWD-035-FNS-C1-H-1 (material no. R165131322) is a genuine Bosch Rexroth ball runner block: ball runner block, FNS, size 35, steel CS, accuracy high, low preload, with ball chain.
Rexroth ball rail systems are interchangeable within one size and accuracy class, so a runner block can be replaced or added on an existing rail.

Compatibility and replacement
Order with the 10-character material number R165131322; in Rexroth codes every character (size, format, length, preload, accuracy class and seals) changes the part, so the type code KWD-035-FNS-C1-H-1 on the nameplate should match exactly.
The values in the table come from the official Bosch Rexroth product data. If your old part carries an older series index, send us a photo of the nameplate and we will confirm the current equivalent.
