Undercarriage sprocket
Our sprockets are manufactured through a precision quench-tempering process, a core heat treatment technology that meticulously controls heating, holding and cooling cycles. This specialized treatment is engineered to optimize the material’s internal microstructure, thereby guaranteeing exceptional mechanical properties including high tensile strength and superior wear resistance. As a result, our products exhibit remarkable structural stability, effectively resisting deformation, bending and fracture even under extreme working conditions such as continuous heavy-load operation, rocky terrain traversal and prolonged underground mining tasks.
Quenching depth specifications:
- Root of tooth: 6–10 mm
- Top of tooth: 18–23 mm
