High-Quality Raw Materials for DUHUI Timing Chain Kits
DUHUI insists on using high-quality raw materials, and all our raw material suppliers must provide material certificates that comply with EN10084 standards.
Our timing chains are made of special alloy steel, which has added alloying elements such as chromium (Cr), nickel(Ni), vanadium(V), molybdenum (Mo) and etc. DUHUI special alloy can significantly improve the hardness, wear resistance and tensile strength of the timing chain. And each DUHUI timing chain is pre-lubricated with DUHUI chain lubricant. Our chain guides are made of high-grade imported nylon resin as raw material, which is resistant to high temperature and wear. Our chain sprockets are made of high-quality alloy steel and have undergone carbonitriding treatment to ensure that the surface hardness can reach 58-62HRC. Most of our customers told us that our timing chain kits are of better quality and have fewer complaints than other suppliers.
Special Processing of DUHUI Timing Chain Kits
DUHUI will do special processing on the easily worn parts of the timing chain kits to enhance hardness and durability.
- Heat Treatment: 850°C high-temperature quenching followed by 220°C low-temperature tempering effectively removes impurities and improves hardness and toughness.
- Carburizing: Surface carburizing improves hardness and wear resistance, achieving a surface hardness of 58-62 HRC.
- Alloying: Rare alloying elements are added to enhance strength, wear resistance, and corrosion resistance.
Unique Design of DUHUI Timing Chain Kits
DUHUI uses advanced CNC machine tools to precisely manufacture timing chain kits. Each component is precisely machined to strict OE standards to ensure zero error. Our high-stability timing chain, combined with an automatic and precise tensioner and a unique gear optimization design, can ensure perfect engagement between the chain and the gear teeth, minimizing tooth skipping and ensuring transmission stability.
The contents of each timing chain kit may be different and should be applied according to the actual situation. Generally, it may include the following parts: timing chain, cam sprocket, crank sprocket, chain tensioner, chain guide, chain gear, etc.
In general, metal timing chains are more durable than rubber timing belts. The service life of a timing chain is about 150,000 kilometers..
The lifespan of a timing chain is affected by many factors. In my experience, three common reasons apply: First, frequent driving in complex road conditions, such as potholes and mountain roads. Second, using low-quality engine oil or failing to change the oil or filter for a long time. Third, failing to perform regular cleaning or maintenance.
