Stainless steel chain: The material of the parts is stainless steel. This kind of chain is suitable for use in the food industry and the occasions susceptible to corrosion by chemicals and drugs. It can also be used in high and low temperature occasions.

Nickel-plated chain, zinc-plated chain, chrome-plated chain: All chains composed of carbon steel materials can be surface treated. The surface of the parts is nickel-plated, zinc-plated or chrome-plated. It can be used in outdoor rain erosion and other occasions, but it cannot prevent thickening. Chemical liquid corrosion.

Self-lubricating chain: Some parts are made of a kind of sintered metal impregnated with lubricating oil. This kind of chain has excellent wear resistance and corrosion resistance, does not require maintenance (maintenance-free), and has a long service life. It is widely used in occasions with high stress, wear-resistant requirements, and cannot be maintained frequently, such as automated production lines in the food industry, high-end bicycle racing, and low-maintenance high-precision transmission machinery.

O-shaped sealing ring chain: There is an O-shaped sealing ring for sealing between the inner and outer chain plates of the roller chain to prevent dust from entering and grease from flowing out of the hinge. The chain is strictly pre-lubricated. Because the chain has super strong parts and reliable lubrication, it can be used in open transmission such as motorcycles.

Rubber chain: This type of chain is based on the A, B series chain with a U-shaped attachment plate on the outer link, and rubber (such as natural rubber NR, silicone rubber SI, etc.) on the attachment plate can increase the wear capacity and reduce Noise, increase shock resistance. Used for transportation. Sharp tooth chain: This kind of chain is widely used in the wood industry, such as wood feeding and output, cutting, conveying table transportation, etc.
Agricultural machinery chain: Agricultural machinery chain is suitable for field operation machinery such as walking tractors, threshers, combine harvesters, etc. This kind of chain requires low cost but can withstand impact and wear resistance. In addition, the chain should be greased or automatically lubricated.

High-strength chain: It is a special roller chain. By improving the shape of the chain plate, thickening the chain plate, fine-blanking the chain plate hole, and strengthening the pin shaft by heat treatment, it can increase the tensile strength by 15-30% and has good impact performance. Fatigue performance.

Side bending chain: This kind of chain has larger hinge gap and chain plate gap, so it has greater flexibility and can be used for bending transmission and conveying.

（Motorcycle Chain）

　　 Escalator chain: used for escalators and automatic pedestrian passages. Due to the long working hours of the escalator, the safety requirements are high and the operation is stable. Therefore, it is required that this step chain must reach the specified minimum ultimate tensile load, the total length deviation of the two paired chains, and the step distance deviation.

Motorcycle chain: It is defined by the purpose of the chain. From the structure of the chain, there are two types: roller chain and bushing chain. From the part used on the motorcycle, it has two types: inside the engine and outside the engine. Most of the chains used in the engine are sleeve chain structures, and the chains used outside the engine are transmission chains used to drive the rear wheels, and most of them use roller chains. Such chains should pay special attention to ensuring fatigue performance.

Agricultural gripping conveyor chain: suitable for walking wheat and rice harvesters, stationary motorized rice and wheat threshers, and semi-feeding combine harvesters.
