Center Guide Silent Chain and Sprockets

All silent chains are made up of stacked rows of flat, tooth shaped driving links that mesh with sprockets having compatible tooth spaces, much the way a rack and pinion mesh. Typically, chains will also contain guide links, whose purpose is to maintain proper tracking of the chain on sprockets. Washers or spacers may be present in some chain constructions. All of these components are held together by riveted pins located in each chain joint. Although all silent chains have these basic features there are still many many different styles, designs, and configurations.

Given the many possible variations in silent chain design it is important to understand some of the options that are available.

Note: Chains must always be accompanied by compatible sprockets. When considering different silent chain designs, it is essential that sprocket compatibility also be considered.

Often the pattern of links with a chain can be varied during manufacture to suit a particular application. Also, other components, such as spacers, can be added to provide a more open chain buildup. Such options are quite common, particularly with conveying chains.
