Qingdao Hengxin Transmission Co., Ltd. is a specialized manufacturer and supplier of motorcycle chains and transmission components. Based in Qingdao, China, the company focuses on the design, production, inspection, and sale of high-strength motorcycle drive chains for domestic and international markets.

Motorcycle chain product range

The company offers standard drive chains, heavy-duty chains, O-ring chains, and X-ring chains. Common specifications include 420, 428, 520, 525, and 530 series, with different tensile strengths, link counts, and surface finishes. The chains are used in street motorcycles, off-road bikes, racing machines, and small-engine drive systems. Sealed-ring chains provide improved lubricant retention, longer service life, and reduced maintenance frequency.

Manufacturing and quality assurance

Production begins with selected alloy steel and precision-formed components. Key steps include punching, heat treatment, shot peening, assembly, pre-stretching, and surface treatment. Dimensional checks cover pitch accuracy, pin diameter, roller diameter, and inner width. Mechanical tests cover tensile strength, hardness, and fatigue resistance. Batch control ensures stable chain length and smooth engagement with sprockets.

Business and customization

Qingdao Hengxin Transmission Co., Ltd. supports OEM and ODM orders with custom specifications, packaging, and branding. The company supplies complete chains, cut-to-length chains, and matched sprocket sets according to customer requirements. It also provides technical consultation, sample confirmation, and flexible delivery for distributors, repair shops, and motorcycle manufacturers.

Application advantages

Motorcycle chains must withstand high speed, repeated shock loads, dust, and varying weather conditions. The company’s chains are designed for accurate pitch control, reduced elongation, and stable power transmission. Reliable surface treatment improves corrosion resistance, while strengthened pins and plates increase fatigue life. These characteristics make the products suitable for demanding riding conditions and continuous use.

The company’s business focus is to provide cost-effective, traceable, and durable motorcycle chain solutions. Through strict process control and customer-oriented service, Qingdao Hengxin Transmission Co., Ltd. aims to build long-term cooperation with OEM partners and aftermarket buyers.
