Different material chain uses are different, according to different material maintenance methods are also different.

Self-lubricating chain: Some parts are made of a sintered metal impregnated with lubricating oil. This kind of chain has excellent wear and corrosion resistance, no maintenance (maintenance-free), and long service life. Widely used in high force, wear-resistant requirements, and can not often maintenance occasions, such as food industry automated production lines, high-grade bicycle racing, less maintenance of high-precision transmission machinery.

O-ring chain: The roller chain is equipped with an O-ring between the inner and outer chain plates to prevent dust from entering and grease from flowing out of the hinge. The chain is rigorously pre-lubricated. Because the chain has strong parts and reliable lubrication, can be used in motorcycle and other open drive.

Stainless steel chain: parts material for stainless steel, this chain is suitable for use in the food industry and vulnerable to chemical, pharmaceutical and other erosion occasions, can also be used in high and low temperature occasions.

Nickel plating chain, galvanized chain, chromium plating chain: all carbon steel material of the chain can be surface treatment, the surface of the parts after nickel plating, galvanized or chromium plating treatment, can be suitable for outdoor rain erosion and other occasions, but can not prevent concentrated chemical liquid corrosion.

Agricultural machinery chain: agricultural machinery chain is suitable for field operation machinery such as walking tractor, thresher, combine harvester, etc. The chain is required to be inexpensive yet impact-resistant and wear-resistant. In addition, the chain should be greased or self-lubricating.

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

Side-bent chain: This chain has a large hinge clearance and chain plate clearance, and thus has a greater flexibility, can be used for bending drive and transmission.

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

Motorcycle chain: Defined by the purpose of the chain, from the structure of the chain, there are two types of roller chain and sleeve chain. From the part used on the motorcycle, it has two types of engine use and engine use. The chain used in the engine is mostly sleeve chain structure, and the chain used outside the engine is the transmission chain used to drive the rear wheel, most of which use roller chain. Special attention should be paid to ensuring fatigue performance of such chains.
