1. Product Introduction

2. Unique Advantages of Heavy Duty + Cottered Structure

① Merits of Heavy Duty Construction

• Thickened inner & outer plates, oversized pins and sleeves, stronger bearing capacity than standard roller chains

• Integrated carburizing quenching & tempering process: hard surface for wear resistance, tough core for anti-cracking against sudden impacts

• Low permanent elongation after long cyclic heavy-load running, stable driving performance, long service lifespan

② Merits of Cottered Type Design

1. Cotter pins lock pin ends tightly, preventing pins from slipping out during high-load vibration operation

2. Easy manual disassembly without professional tools; convenient to adjust chain length or replace damaged individual links

3. Perfect for machinery that needs regular inspection, maintenance and periodic length trimming

4. Higher running safety under variable load and impact conditions

7. FAQ

1. What is the difference between cottered heavy chain and riveted heavy chain?

   Cottered type can be disassembled freely for maintenance and length adjustment; riveted type is permanently sealed, non-detachable, more suitable for uninterrupted long-running fixed equipment.

2. Can you cut chains into customized lengths?

   Yes, we can process any required length and assemble matched connecting links as your request.

3. Which surface finish is for outdoor damp usage?

   Galvanized surface treatment is recommended for excellent rust prevention.
