Product Description

Product Description

    

       Heavy-duty cotter pin roller chains are the optimal solution for high-load, high-impact, and harsh operating conditions, particularly in industrial applications demanding maximum safety, reliability, and extended service life.

 

Core Advantages of Heavy-Duty Cotter Pin Roller Chains
Advantage	Technical Description
1. Ultra-High Load Capacity	Features reinforced link plates and hardened pins/bushings, offering 30%~50% higher tensile strength than standard B-series chains (e.g., 80H heavy-duty chain reaches 300kN+ breaking load).
2. Secure & Reliable	Cotter pin locking mechanism prevents pin detachment, ideal for high-speed, vibrating, or shock-load conditions.
3. Superior Wear Resistance	Pins and bushings undergo deep carburizing & quenching (HRC 58-62), with hardened rollers, extending service life 2~3x longer than standard chains.
4. Easy Maintenance	Cotter pin design enables quick disassembly/replacement of individual chain sections, minimizing downtime.
5. Corrosion-Resistant Options	Available with zinc plating, Dacromet coating, or stainless steel for wet/chemical environments (e.g., mining, metallurgy).
