Wave Disc Spring Basics
When the load is static or the working range is small, and the allowable amount of axial space is limited, the use of a wave washer is an efficient method of obtaining the required loading. Loads obtainable from wave washers are usually in the range of a few pounds to hundreds of pounds. These springs are often used as cushion springs or cushion spacers between parts on shafts, or to take up the expected amount of variation in assembled parts. Wave washers can be made in a very large range of sizes.
Note: Stock parts online are manufactured using spring steel. Call for availability if stainless is desired.
