Stainless steel chain is a common transmission power device. It reduces friction through a hyperbolic arc "chain" design. It is used in places where the power is larger and the running speed is slower. Compared with belt drives such as fuel tanks, pneumatic compressors, etc., it has obvious advantages, but the transmission speed cannot be too fast, because the flexibility of the chain is not as good as that of the belt drive. Chains are divided into conveyor chains according to their different uses and functions (mainly used for conveying materials). Transmission chain (mainly used to transmit power chain). Special chains (mainly used for special mechanical devices, there are four types of chains with special functions and structures). Energy chains (mainly for energy chains and hoisting chains). The chain structure series is in the same kind of products, according to the basic structure of the chain, that is, according to the shape of the parts, the parts and parts that mesh with the chain, the size ratio between the parts and other chain product series. Stainless steel chains are especially suitable for areas with high corrosion resistance, cleaning or some chemical requirements, as well as high and low temperature occasions.
