Connecting links for chains

Connecting links, also known as joining links or master links, are used to close a chain into a loop or to join two lengths. They replace one outer link and have the same pitch as the chain, so they do not change its working length.

Connecting links - a chain master link for quick repair without removing the sprockets

With a connecting link you can fit a chain without removing sprockets and shafts, shorten it after it has stretched or join two lengths into one. The repair is quick, and the machine gets back to work without long downtime. It is worth keeping a few links in reserve - they cost little but can save the day in the busy season. Links for roller chains are made in the same way as the chains: from C45 steel, with components hardened separately before assembly.
