High-Rigidity Linear Drives for Heavy-Duty Machining Centers

In heavy-duty CNC and industrial machines, high rigidity and accuracy define performance. YYC offers precision racks meeting DIN 5-DIN 10 grades, ensuring micron-level stability during long-axis movement.

These racks are typically produced from S50C or SCM440, hardened by induction to HRC 50–60. Common modules are M2 to M8, depending on machine size. They provide superior stiffness and wear resistance under high torque and load conditions.

Used in gantry machining centers, boring mills, and portal-type machines, YYC racks enable long-stroke precision motion where ball screws reach their limits. With pitch error below 0.03 mm/m, the rack system maintains alignment accuracy across multiple meters of travel.

By combining advanced grinding, heat treatment, and tooth inspection technologies, YYC ensures long life and consistent performance. Our racks are preferred by global machine tool OEMs who demand precision, repeatability, and strength for large-scale metal cutting and industrial automation.
