Metric Wave Spring Washers DIN 137B, Zinc Plated

Metric Wave Spring Washers

Also known as:  

Multiple Wave Washers, Spring Washers, Wave Springs, Wave Washers, Wavy Washers

Metric wave spring washers are thin metal washers that often have three or four "waves." Their wavy design allows them to act as a spring that exhibits a fairly linear spring rate between about 20% and 80% of their available deflection. When wave spring washers are loaded (compressed), their outside diameter (OD) increases as their inside diameter (ID) decreases so allow space for these dimensional changes. Wave spring washers can be stacked but must be separated by a flat washer.
      Wave spring washers are used to provide a preload between two surfaces and in situations where axial space is limited. Common applications include maintaining fastener tension, acting as take-up springs to compensate for tolerance variations in assembled parts and as cushion spacers. Reducing end play in motors and providing a preload for bearings are two examples.
      Typical wave spring washer size ranges from M3 to M20. Washer size refers to its nominal hole size and is based on screw size—its OD is always larger. Free height is the minimum height of the unloaded washer. Material thickness is the thickness of the washer material only and does not include wave height. Thickness for M3 and M3.5 washers is the same as regular metric flat washers of the same size. For larger sizes, it is about half the thickness of the same size flat washer.
