Automotive components are generally relatively precise and small, and the automotive gears must also have high resistance to breakage,so the tooth faces should have strong resistance to pitting, wear,high temperatures and strong vibration capability, we have modified the overall gear and tooth profile of the gearbox to meet the needs of small volume and low noise.For example automobile microelectronics, electric tail door, EPB, electric window, steering wheel adjustment, electric seat, damping controller and so on.We provide you with customized solutions.
