Curved Spring Washers

  Curved (single wave) spring washers are commonly used for simple spring applications. Curved washers exert relatively light thrust loads and are often used to absorb axial end play or as lock washers for fasteners. The height of the form and material thickness are variables which can be adapted to a specific load/deflection function.
