Complete list of chain specifications and dimensions

2023-05-17 18:18:25

Most chains have been listed as international standards, developed country national standards, or Chinese national standards, and the chain number identification of these chains is not difficult to find from the standards. However, in international trade exchanges, chain enterprise chain numbers from countries such as the United States, Japan, Germany, Italy, and Belgium are often popular, leaving our chain entrepreneurs at a loss and helpless. Therefore, the author provides some guidance on this, which may be slightly beneficial for those engaged in chain trade.

The chain specifications and sizes are divided into four types based on different purposes and functions: transmission chain, conveyor chain, traction chain, and specialized special chain.

1.1 The transmission chain is mainly used for transmitting power.

1.2 The conveyor chain is mainly used for conveying materials.

1.3 The traction chain is mainly used for pulling and lifting chains.

1.4 Specialized special chains are mainly used for chains with special functions and structures on specialized mechanical devices.

In similar products, the chain product series is divided based on the basic structure of the chain, which includes the shape of the components, the parts and positions that mesh with the chain, and the size ratio between the parts.

Chains of the same variety are classified into different specifications based on pitch, number of rows, chain width, and ultimate tensile load.
