Helical rack and pinion CHTGH03010-DIN5

groundprecision

Product overview
CHTGH-DIN5 helical ground rack manufactured from S50C. Right-hand helix angle 19°31′42″. Teeth are induction hardened to HRC 50–55 and ground; rack is ground on all sides after hardening to ensure dimensional stability. Total pitch error is controlled to ≤ 0.030 mm per meter at 25°C. Designed for high-precision machine tools and CNC equipment operating in temperature-controlled environments.
