Huzhou Dongyao Chain Industry Co., Ltd. is one of the leading manufacturers and suppliers of 428h gold drive chain in China. With abundant experience, we warmly welcome you to buy high quality 428h gold drive chain from our factory. Also, custom service is available.
Product Overview
The DYLinkar 428H Gold Drive Chain is a copper-coated reinforced transmission chain designed for small and medium-sized displacement vehicles. With a specification of 428H, it achieves heavy-duty upgrades based on the standard 428 model by thickening the chain plates. The inner and outer chain plates are treated with an electroplated copper surface layer, presenting a uniform golden yellow appearance, which offers both rust protection and visual recognition. The chain is made of high-quality alloy steel and undergoes automatic mesh oven heat treatment and shot blasting strengthening. Its tensile strength reaches 21.6 kN. Before leaving the factory, it undergoes mechanical pre-stretching and is equipped with spring-type ball joint links, making it ready for installation.
Key Features
Copper electroplated surface layer - Balances rust prevention, corrosion resistance and visual identification.
01
The thickness of both the inner and outer plates is 2.0mm, and the tensile strength is 21.6 kN.
02
The pin and the chain plate achieve a deep hardened layer, thereby extending the fatigue life.
03
The pin and the chain plate achieve a deep hardened layer, thereby extending the fatigue life.
04

FAQ
Q:What is the proper procedure for installing a new industrial roller chain?
A:Installing a new industrial roller chain involves safety first (power off), followed by inspecting sprockets & shafts, ensuring proper alignment, fitting the chain around sprockets, correctly joining the ends with a master link (using a chain puller for tension), setting the correct sag/tension (approx. 1/4" per foot of span), and finally, lubricating and testing for smooth operation, with a recheck after initial use.
Q: What are the most common causes of premature roller chain failure?
A:The most common causes of premature roller chain failure are improper lubrication, overloading, contamination, and misalignment, often working together to cause accelerated wear, elongation, and fatigue.
