Bosch Rexroth R100003061 Steel Shaft 30 H7 CR

Rexroth R100003061 is a solid steel shaft with a 30 mm diameter, H7 tolerance, and a hard chrome-plated CR finish. It belongs to Bosch Rexroth’s WV/R1000 precision steel shaft family and is designed for use with Rexroth linear bushings and shafts to create rigid, accurate linear guidance in automation, robotics, and CNC equipment. The 30 mm shaft uses a hard chromium plating roughly 10 µm thick, delivering a surface hardness near 1,000 HV, while the underlying steel offers a minimum hardness around 60 HRC (about 700 HV). The catalog provides an example length of 480 mm for the R1000 030 61 variant, with a range of lengths available to match different installations. Typical applications include precision motion assemblies, linear slides, and other systems that rely on tight dimensional tolerances and reliable compatibility with Rexroth bushings.
