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