Frequently Asked Questions
What international standards do your roller chains comply with?
Our chains are manufactured to meet a comprehensive range of global standards, including ISO, DIN, ASA, ANSI, JIS, and GB, ensuring compatibility and reliability across different regional requirements.
What materials are used in the construction of your chains?
We use high-grade Carbon steel 40Mn for the main structure, specialized #10 steel for the rollers and bushes, and 40Cr steel for the pins to ensure maximum durability and wear resistance.
How do you ensure the strength and quality of the chain parts?
All spare parts undergo rigorous heat treatment (quenching and tempering) within reasonable tolerance ranges. Our chains feature a tensile strength that is typically 15% higher than standard requirements.
Do the chains come pre-lubricated?
Yes, all our chains are treated with high-quality grease for excellent lubrication, reducing friction and extending the operational life of the product.
What types of chains can you provide besides standard roller chains?
In addition to standard roller chains, we produce leaf chains, conveyor chains, drive chains, agricultural chains, industrial sprockets, and chain couplings.
Is your production process certified?
Yes, our factory is ISO 9001 certified, ensuring that our management and manufacturing processes consistently deliver high-quality products.
