Wave spring refers to the elastic component on the metal thin circular ring featuring a number of wave troughs. It is usually used for the circumstances where the load and deflection are not quite heavy and less spring stiffness shall be required and axial pre-pressure imposed. Typical materials include 60Si2MnA(SAE 9260), 50CrVA (SAE 6150)and various stainless steels. The surface treatment methods of wave spring include bluing, phosphatization, galvanization, electrophoresis and etc. Size:OD range from 27.5mm to 238mm For more detail,pls feel free to contact with us.
