Chain with special function and structure, which is mainly used for special mechanical equipment. In the same series of chain products, according to the chain components of the material, the form of chain attachments and hinge structure classification.
According to the classification of pitch: the common market is called: 4 points (P=12.7), 5 (P=15.875), 1 inch (P=25.4), a chain 1 and a half inches and so on the same variety according to the pitch, row number, chain width and ultimate tensile load of different specifications, the chain size can be directly based on the fly wheel number of speed after determining the resolution;
