What are Garter Springs?

Garter Springs are a helical extension or compression spring which ends are connected to allow the spring to be held in a circle, the one end may be coned/looped.

Their main applications are in oil seals, conveyor systems and motor drive belts.

Connecting the ends can be accomplished in several ways such as; tapering one end and screwing into the opposite end, interlocking the end loops, soldering or using another short extension spring as a connector by screwing into both ends of the spring.

What Garter Springs are used for

Garter Springs are mainly used in Oil seals, of course they have many other uses such as; shaft seals, belt driven motors and electrical connectors.

This is due to the fact that garter springs exert outward radial forces while extension garter springs exert inward radio forces.
