After the motorcycle chains are assembled on the automatic production line, 100% on-site screening is conducted. In addition, our quality team performs comprehensive testing using professional equipment to evaluate key performance indicators, including chain length, tensile strength, wear resistance, and fatigue resistance.
For the length test, each chain is laid flat on the measuring instrument, and multiple positions are measured to ensure consistent and precise length across the entire chain. The tensile strength test determines the chain’s breaking load—the maximum force it can withstand before failure—which is a critical indicator of product reliability and safety.
The wear test simulates real-world operating conditions to assess the chain’s wear level and resistance, providing important insights into durability and service life. Hengjiu chains are engineered for strong wear resistance to ensure long-lasting performance.
Fatigue testing evaluates the chain's ability to withstand repeated loading and unloading cycles without failure, ensuring stable performance under continuous use.
Our motorcycle chains are strictly controlled across four key quality indicators: initial elongation resistance, fatigue strength, breaking load, and dimensional accuracy—guaranteeing dependable performance and peace of mind on every ride.
