WAVE WASHER

A WAVE WASHER is an elastic washer with a continuous series of wave peaks and valleys. It may also be referred to as a Wave Spring Washer. When subjected to axial compression, it generates a spring-back force, making it suitable for compensating for assembly clearance, maintaining preload, and reducing component movement.

Provides Uniform Elastic Preload

When compressed, multiple wave peaks work together to generate axial spring-back force, helping distribute contact pressure more evenly across the assembly.

Compensates for Assembly Clearance

A WAVE WASHER can absorb clearance variations caused by machining tolerances, component wear, and thermal expansion or contraction, helping maintain proper fit within the assembly.

Reduces Axial Movement

Proper preload can help limit axial displacement of bearings, gears, shafts, and rotating components, reducing abnormal noise and vibration.

Thin Profile Saves Installation Space

The wave-shaped structure can provide relatively long compression travel within limited axial installation space, making it suitable for compact and precision mechanisms.

Suitable for Various Precision Assemblies

WAVE WASHERS are commonly used in motors, bearings, gears, electronic equipment, automotive and motorcycle components, automation equipment, and precision instruments.
