08B chain refers to the 4-point chain. This is a European standard chain with a pitch of 12.7mm. The difference from the American standard 40 (the pitch is the same as 12.7mm) lies in the width of the inner section and the outer diameter of the roller. Since the outer diameter of the roller is different, the two are used The sprockets also have some differences in size. 1. According to the basic structure of the chain, that is, according to the shape of the components, the parts and parts meshing with the chain, the size ratio between parts, etc., the chain product series is divided. There are many types of chains, but their basic structures are only the following ones, and the others are all deformations of these types. 2. It can be seen from the above chain structures that most chains are composed of chain plates, chain pins, bushings and other components. Other types of chains only have different changes to the chain plate according to different needs. Some are equipped with scrapers on the chain plate, some are equipped with guide bearings on the chain plate, and some are equipped with rollers on the chain plate, etc. These are modifications for use in different applications.
