Helical rack and pinion CHTGH02520-DIN6

groundprecisionlinear

Product overview
Helical ground rack from series CHTGH-DIN6 manufactured in S50C. Right-hand helix angle 19°31′42″. Teeth induction-hardened to HRC50–55 and ground; rack ground on all sides after hardening. Total pitch error Fp/2000 ≤ 0.046 mm (measured at 25°C). Designed for high-precision linear transmission in industrial machinery including CNC machines, woodworking equipment, laser cutters, tube bending machines, 5-axis machining centers, suspended rails and robotic axes.
