With the booming market of large-displacement motorcycles, more and more people are playing with motorcycles in recent years. But when it comes to the chain of motorcycles, many people have only a vague understanding of it. Some even think that the motorcycle will move, and it is fine as long as the chain is not broken. However, the quality of the chain has a huge impact on the riding safety and riding experience of the motorcycle, and it must not be underestimated.

There are hundreds of chains on the market. How to classify the chains and how to choose them may be confusing for beginners. Even experienced motorcycle riders may have some wrong concepts without knowing it. Next, let Hengfa Chain Industry share the knowledge related to motorcycle chains with you, hoping to help you.

Chain brand

There are quite a lot of chain brands. For ordinary people, Hengfa Chain Industry's motorcycle chains and industrial chains can basically meet everyone's needs.

Types of chains

Generally, the common classification can be divided into two types: oil-sealed chains and non-oil-sealed chains. The so-called oil seal chain is an oil seal between the inner and outer chain plates (as shown in the red circle on the picture), which wraps the lubricating oil in the middle to help lubricate the chain. Chains without this oil seal are called non-oil seal chains.

Chain structure

From the perspective of oil seal chains, they can be roughly divided into six major structures: inner chain plates, outer chain plates, pins, bushings, rollers, and oil seals.

In the manufacture of chains, the precision and wear resistance of pins and bushings are very important. Usually, the main reason for the elongation of the chain we say is the wear of the pins and bushings. Don't underestimate this little difference. For a chain with 100 sections, as long as each section is elongated by 0.1mm, the 100 sections will become one centimeter longer. And when the chain starts to wear, the wear rate will increase rapidly, so be especially careful.

Regarding the chain pin, in addition to high processing accuracy, it must also be a right cylinder to maintain a fixed gap with the bushing and reduce unnecessary wear. In addition, chromium carbide must be plated on the outer layer of the pin to increase rigidity and hardness to reduce wear. Metal that is too hard tends to become brittle, and the center must be properly heat treated to keep the center flexible.

For the bushing part, the early chain bushings were formed by bending steel plates. Although this can reduce costs, under high-strength conditions, the joints are prone to deformation, causing uneven rotation. With the advancement of processing technology in recent years, the bushings of high-quality chains have been processed by cold forging, which has better overall durability.
