Helical rack and pinion CHTGH02005-DIN6

steelgroundprecision

Product Overview
CHTGH02005-DIN6 is a helical-tooth ground rack manufactured from S50C steel. It features a right-hand helix angle of 19°31′42″. Teeth are induction hardened to HRC 50–55 and ground; the rack is ground on all faces after hardening. Total pitch error is Fp/500 ≤ 0.032 mm (measured at 25°C). The part is intended for high-precision linear transmission applications in CNC machines, robotics and automated systems.
