Smooth surface finish reduces aerodynamic drag when integrated into the vehicle chassis. Optimized internal geometry reduces friction, lowering energy loss and extending component life. Compact dimensions save space in the engine bay, allowing for more flexible vehicle design. Effective vibration‑reducing capability safeguards internal gears from damage due to sudden bumps and jolting motions. Equipped with shock‑dampening functions, it defends inner gear structures against harm from abrupt road‑induced jolts., Manufacturer: NADCFN
