Huzhou Dongyao Chain Industry Co., Ltd. is one of the leading manufacturers and suppliers of 420h motorcycle chain in China. With abundant experience, we warmly welcome you to buy high quality 420h motorcycle chain from our factory. Also, custom service is available.
Product Overview
The DYLinkar 420H motorcycle chain is a reinforced non-sealed chain designed for small and medium-sized engine displacement vehicles. With a specification of 420H, it has a thicker chain plate compared to the ordinary 420 chain, which is suitable for higher load transmission requirements. The chain is made of carbon alloy steel and undergoes controlled atmosphere heat treatment and shot blasting treatment, with an ultimate tensile strength of 21.6 kN. It is pre-stretched before leaving the factory to eliminate initial elongation, and is equipped with spring clip-type universal joints. The product is practical in positioning and is suitable for daily riding and light off-road scenarios.
Key Features
Grade H thickened chain plate, with tensile strength reaching 21.6 kN.
01
The carbon alloy steel undergoes heat treatment and shot peening in a mesh belt furnace, resulting in uniform hardness of the chain plates and pin shafts.
02
The carbon alloy steel undergoes heat treatment and shot peening in a mesh belt furnace, resulting in uniform hardness of the chain plates and pin shafts.
03
The pre-stretching at the factory reduces the initial elongation, and there is no need for frequent adjustments after installation.
04
Spring-type snap-fit connection, allowing for easy assembly and disassembly without the need for special tools.

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.
