Bosch Rexroth R165181920 Linear Guide

Bosch Rexroth R165181920 is a high-precision B.RUNNER BLOCK CS for a ball rail linear guide, configured as KWD-020-FNS-C1-U-1, and built for applications that demand maximum rigidity and accuracy. The carbon steel runner block measures 63 mm in width and 75 mm in length, and it rides on a matching profiled rail to deliver smooth, straight-line motion with tight tolerances. Core specifications include a dynamic load capacity of 23,400 and a static torsional moment load Mt0 of 380, along with a preload of 380, all of which contribute to excellent load distribution and backlash resistance in demanding environments. The unit ships with initial lubrication and preservation, and lists a maximum acceleration of 500 and a maximum speed of 5, making it suitable for precision automation tasks that require rapid, repeatable motion. Designed for industrial automation, robotics, and machinery where precise positioning is critical, this Rexroth block is part of Bosch Rexroth's ball rail family and is intended to be paired with a compatible profiled rail to form a complete linear guide system.
