HEAVY DUTY SERIES COTTERED TYPE ROLLER CHAINS
Product Description

Heavy duty roller chain is a high-strength industrial transmission chain designed for extreme load conditions, characterized by robust construction, enhanced wear resistance, and reliable power transmission. It is widely used in heavy machinery, mining, port logistics, and industrial production scenarios where standard roller chains cannot withstand high loads, shock forces, or prolonged harsh operation.
Application:
Heavy machinery: such as mining machinery, metallurgical equipment, lifting machinery, etc., these equipment usually need to withstand a large workload and impact.
Transmission system: such as cars, motorcycles, ships and other transmission systems, as well as wind power, hydropower and other energy field transmission devices.
Conveying equipment: such as conveyors, elevators, etc., used for conveying and lifting materials.
