Wave Washers

Wave washers are spring elements used to maintain controlled axial load within an assembly.

G-Fast supplies wave washers per print or specification across a full range of materials, configurations, and load-deflection requirements including carbon spring steel, stainless alloys, copper alloys, and high-temperature materials.

Where a flat washer distributes load, a wave washer manages it—maintaining consistent preload while accommodating thermal expansion, tolerance variation, and dynamic movement within the joint.

How Wave Washers Work

A wave washer is a formed ring with controlled wave geometry that deflects under load.

As the washer compresses, the waves flatten progressively, storing spring energy and applying consistent axial force back into the assembly.

This allows the washer to maintain preload, compensate for dimensional variation, and absorb vibration and movement.

Spring performance is determined by wave count, material thickness, ring diameter, and material properties.

Configurations of Wave Washers

Single Wave (Crescent)

Light load, high deflection range. Used for spacing, cushioning, and light preload applications.

Multi-Wave (3-Wave, 4-Wave)

Balanced or higher spring rates depending on wave count. Used in motors, bearings, and precision assemblies.

Nested / Multi-Layer

Stacked to increase travel (series) or load capacity (parallel).

Overlap (Open Profile)

Open ring design allows installation without full disassembly. Used in maintenance applications.

Fasteneering® Insight

Wave washers are engineered into the assembly not simply selected.

Performance depends on preload, deflection range, operating temperature, and cycle life.

G-Fast reviews supplied specifications for manufacturability, material suitability, and cost efficiency while working strictly to customer-defined requirements.

Engineering Review

Every inquiry begins with your print or defined specification.

We review for load-deflection feasibility, material performance, manufacturability, and cost efficiency.

All changes must be approved by your engineering team and incorporated into updated documentation prior to production.

Manufacturing Support

• Standard and custom configurations
• Material and heat treatment per specification
• Controlled spring characteristics
• Small batch through production runs
• Blanket orders and scheduled releases

How G-Fast Supports Wave Washer Programs

G-Fast supplies wave washers produced to customer specifications and recognized industry standards.

For applications requiring specific materials, spring characteristics, finishes, or performance requirements, we review supplied drawings or specifications for manufacturability, feasibility, and cost efficiency prior to production.

Where appropriate, we may suggest alternative materials, geometries, or production methods. Any recommended changes are reviewed and approved by the customer’s engineering team and incorporated into updated documentation before manufacturing begins.
