One-way clutch, also known as overrunning clutch, is widely used in motorcycle engine, new energy vehicle transmission, construction machinery, agricultural machinery, mining machinery, packaging machinery, printing machinery and food machinery and other fields.

Overrunning Alternator Pulley (OAP), is usually installed in automotive alternators to solve the problem caused by engine speed fluctuations to the front end accessory transmission system. It can improve belt slip rate, reduce belt vibration and tension and tensioning wheel travel, effectively extend the life of the wheel train and improve NVH.

Precision machined parts, mainly include automotive torque converter inner and outer race, automotive transmission oil pump sleeve and blade ring, brake system ball screw, Electro-Hydraulic Brake (EHB) three-way valve, Automatic Parking Braking (EPB) piston, Electronic Stability Controller（ESC）tappet and pump piston and all kinds of pins.
