Helical rack and pinion CHTGH08020-DIN6

groundprecision

Product overview
Helical-tooth ground rack CHTGH08020-DIN6 manufactured in S50C. Teeth are induction-hardened to HRC50–55, ground on the tooth surfaces and on all faces after hardening. Right-hand helix angle 19°31′42″. Total pitch error Fp/1920 ≦ 0.048 mm (measured at 25°C). Designed for smooth engagement, reduced noise and high torque transmission. Typical applications: precision CNC machines, woodworking machines, laser cutters, tube benders, 5-axis machines, gantry axes and robot arms. Surface roughness Ra0.8.
