Our precision gears drastically reduced the noise and downtime of our embroidery machines—transmission accuracy has stayed consistent even after 8,000+ hours of operation. The short-cycle customization service also helped us launch new equipment 2 weeks ahead of schedule.
Our team relies on Jinyi’s small-module gears for our robot transmission systems—their high precision cuts operational noise by 30%, and the 10,000+ hour service life has cut our maintenance costs significantly. The custom design turnaround was impressively fast too.
Robust gear designs power critical industrial workflows. Our precision-machined spur gears ensure consistent torque transfer, while our hardened tooth profiles resist wear in high-cycle applications. Every component is calibrated to tight tolerances, ideal for automotive drivetrains and manufacturing equipment.
