Helical rack and pinion CHTGH06020-DIN6

steelgroundprecision

Overview
The CHTGH06020-DIN6 is a helical teeth ground rack manufactured in S50C steel. Teeth are induction hardened to HRC50-55 and ground on the tooth flanks and all sides after hardening. Right-hand helix angle is 19°31'42". Total pitch error is controlled to Fp /2000 ≦ 0.048 mm at a reference temperature of 25°C. This rack is designed for precision linear transmission in heavy-duty CNC and automated equipment where low noise and high load capacity are required.
