A washer with a "wave" in the axial direction, which provides spring pressure when compressed. Wave washers, of comparable size, do not produce as much force as Belleville washers. A wave spring is a spring made out of pre-hardened flat wire in a process called, 'on-edge-coiling', also known as 'edgewinding'. The number of turns and waves can be easily adjusted to accommodate stronger force or meet customers' specific requirements.
