Helical rack and pinion CHTGH04020-DIN6

carbon steelgroundprecision

Product Overview
CHTGH-DIN6 is a helical-tooth ground rack manufactured in S50C. The rack features a right-hand helix angle of 19°31′42″, induction-hardened to HRC 50–55 and precision ground on teeth and all sides after hardening. Total pitch error per meter is controlled to 0.048 mm (measured at 25°C). Designed for industrial motion systems requiring high torque and low noise.
