Bosch Rexroth R165141420 Flanged Runner Block

The Bosch Rexroth R165141420 Flanged Runner Block is a 45 mm-wide ball-rail carriage designed for smooth, high-load linear motion along Rexroth ball rails, delivering precise travel in automation and machine-tool axes. Made from carbon steel (CS) and configured as the FNS variant (Flanged, Normal height, Seals), it ships with universal seals fitted as standard and a low preload setting, and it comes without ball chain. In applications such as CNC tables, automation slides, and robotics axes, it provides consistent low-friction carriage along the rail. The part number R165141420 corresponds to KWD-045-FNS-C1-N-1, identifying a 45 mm-wide unit with standard accuracy, low preload, and without ball chain configuration.
