Product Diagram
Product Features
Heavy-Duty Forged Steel with Deep Induction Hardening: Forged from high-grade alloy steel (such as 35MnB) and subjected to precise quenching and deep induction hardening on rail surfaces (achieving HRC 53-58 hardness). The deep wear layer effectively absorbs severe impact loads and withstands high-abrasion environments without cracking or premature fatigue.
Precision Fit and High Shear Resistance: Engineered with precise pitch control and tight manufacturing tolerances to guarantee seamless engagement with sprockets, idlers, and track rollers, minimizing travel drag and derailment risks. Complemented by high-strength master pin retention, it easily withstands extreme side-shear forces under heavy-load operations.
