TENSIONER SPRING TYPE 7 3/8 A

A spring is an elastic object that stores mechanical energy. Springs are typically made of spring steel. There are many spring designs. In everyday use, the term often refers to coil springs. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length.

A tensioner is a device that applies a force to create or maintain tension. The force may be generated by a fixed displacement or by stretching or compressing a spring; by changing the volume of a gas; by hydraulic pressure; or by gravity acting on a suspended mass.
