Wave Washer – Space-Saving Axial Load Support
About the Product
Wave washers are thin washers with a wavy, spring-like contour, typically containing three or more waves. They are designed to exert a medium force when compressed, making them highly effective for cushioning and maintaining small-to-medium loads in limited-space applications, primarily used to take up axial end play in bearings and assemblies.
- Excellent for use in assemblies with restricted axial space.
- Provides consistent light-to-medium spring force.
- Effective at taking up bearing end play and reducing rattle.
- Available in single-turn, multi-turn, and overlapping styles.
Due to their low profile, wave washers are a common choice over traditional coil springs when space is a critical constraint. They are essential in precision components like gearboxes, clutches, and electrical motors to ensure silent and smooth operation by pre-loading components.
Technical Specifications
Characteristics: Flat washers with a sinusoidal wave pattern to create axial elasticity.
Measurements: Wire Thickness: 0.1 mm – 4.0 mm. Outer Diameter: 5 mm – 150 mm. Wave Count: 3 to 6 waves typically.
Configurations: Single-turn, multiple-turn, and gap-type available. Custom material options include Stainless Steel, Beryllium Copper, and Phosphor Bronze.
Rate or Stiffness: Low to Moderate (0.5 N/mm – 15 N/mm), dependent on material and wave height.
Service Life: Good for static loading and medium-cycle dynamic applications; long-lasting in non-fatigue environments.
Tolerances: Controlled wave height (Wh) and precise outside diameter (OD) for consistent performance.
Applications: Bearing pre-loading, clutch systems, valve assemblies, mechanical seals, vibration dampening, and small electric motors.
