DIN 137B Spring Washers, also known as waved spring washers, are thin metal washers with a wavy design that allows them to function as a spring. This wavy design provides a fairly linear spring rate within a specific deflection range. When compressed, their outside diameter increases while their inside diameter decreases, so space must be allowed for these dimensional changes. They can be used to provide a preload between two surfaces and in situations where axial space is limited. Common applications include maintaining fastener tension, compensating for tolerance variations in assembled parts, reducing end play in motors, and providing a preload for bearings. DIN 137 B is recommended for new designs over DIN 137 A. They are typically made from spring steel EN 10132-1/4 (C60S) and are available in various finishes such as self-finished and oiled, or mechanical zinc plating. Available in metric sizes.
