 Wave Washers

Spring washers or wave washers are specifically designed to provide a compensating spring force and sustain a load or absorb shock.

Many design variations have evolved to best serve these basic functions.

Spring washers are typically used in applications where assemblies need a part to take up play, eliminate rattle, maintain assembly tension, compensate for expansion or contraction in materials after assembly, or to absorb intermittent shock loads and provide a controlled reaction under dynamic loads.

Load and deflection are the key performance characteristics of a spring washer.

Design considerations to control load and deflection are typically O.D. or bearing surface, free height and material thickness.

Formulas and calculations are available to assist in choosing the right spring washer for your design.

A variety of design styles are available as standards. Dimensional variations to these standards are also readily provided.
 
   
 SINGLE WAVE

The most commonly used spring washer. Provides the greatest amount or spring action for its size and gauge.
 
   
 V WAVE
The `V` form increases load carrying Capacity but reduces resilience compared to the single wave.
 
   
 SINGLE WAVE FLAT RIM

Provides flat contact to eliminate surface scoring. Flat rim carries more load with same material thickness than the single wave.
 
   
 THREE WAVE

Provides greater load-bearing capability due to three-point contact and sharper curves and waves.
 
   
 FOUR WAVE

Four waves further increase loading-bearing capabilities.
 
   
 FINGER WASHER

Six resilient fingers on the outer periphery assure balanced pressure and directs the pressure away from the I.D.
 
   
 CONICAL WASHERS

Provides great load bearing capacity. Spans holes, and maintains high tension in screw and nut assemblies. Available in plain or toothed periphery styles.
