Wave Spring Washer (DIN 137)

The Wave Spring Washer is designed with a wave-shaped profile to provide stable elastic force in limited spaces. When tightened with bolts or nuts, it maintains continuous pressure, absorbs vibration and displacement, and prevents loosening caused by clearance or load variation.

In addition to the standard type, a bearing type is available, which is selected according to bearing numbers. This makes it widely used for precision bearing assemblies, ensuring proper preload and gap compensation.
