Roller Chain Offset Link
Roller chain offset links are used for making repairs and for adjusting the length of a roller chain. They are also commonly known as half links because when assembled they only add half of a pitch. A standard offset link consists of on roller, one bushing, one pin with a cotter, and two offset side plates to hold everything in. There are three different quality levels available for most sizes of our roller chain offset links; Economy Plus for most general industrial and agricultural applications, General Duty Plus for more demanding and higher-speed applications, and Premier Series for the toughest and most demanding applications.
2-Pitch Offset Link
2-Pitch offset links are also available. This style is typically used with small pitch roller chains as well as some problem solver chains. 2-pitch offset links consist of a standard offset link with a roller link riveted to it.
