Wave springs can be used in a variety of industrial applications. For example in a pressure release valve a wave spring is used in order to maintain an exact load applied to the top sealing plate. Wave springs are also used in clutch drives. The most common application for wave springs is a bearing preload arrangement. Using the wave spring within the bearing lowers operating temperature, reduces vibration, minimizes wear, and provided for a quieter and smoother performance. Wave springs can also be found in very common household products. Sprinkler valves contain wave springs in order to maintain constant pressure on the pop-up-head, firmly holding it closed. The water pressure will overcome the springs force and the water will be released, after the water pressure decreases the force of the spring will regain statute and the pop-up-head is resealed. One of the last major applications of wave springs are the ones found within the gear box drive. The wave spring greatly reduces the vibration within the gear box. Also, the spring takes up tolerances that accumulate in the plastic components of the box.
