SAE 8620 Alloy Steel Precision Gear
Description
SAE 8620 alloy steel precision gears are produced with American standard steel and GB-20CrNiMo (Chinese standard) materials. Gears manufactured using these materials feature excellent processing properties with minimal machining deformation and good fatigue resistance. These precision gears provide steady transmission with minimal noise.
Application scope
SAE 8620 alloy steel precision gears are designed for mechanical transmission systems used in cars, mixers, textile equipment, printing machines, agricultural machinery, and other engineering equipment.

Features
1. SAE 8620 alloy steel precision gears mesh smoothly with minimal meshing noise.
2. The face of the gear undergoes a shot peening process after grinding. The surface stress state is thus generated, so greatly improving the contract strength of the teeth to extend the useful life of the gear wheel.
