Wave spring washer

What is a wave washer?

A wave washer is characterized by its sinusoidal shape, which gives it the elasticity needed to compensate for assembly play. Generally used to complement ball bearings or other mechanical components, they exert a medium pressure force when the nut or screw is tightened. For example, they are often used in ball bearings to compensate for axial play.

• Material: often made of steel or stainless steel to withstand corrosive environments.

• thickness: depending on the number of parts to be assembled, the right thickness should be chosen to obtain the right block height.

• Standardnumber: each format is identified by a specific number (e.g. DIN standards) which guarantees standardized dimensions.

Features and benefits of corrugated washers

• Vibration reduction: Thanks to their shape, these washers better absorb shocks and vibrations, thus preserving component life.

• Greater tightening precision: Their ability to take up axial play helps maintain constant tension, ensuring greater precision in the tightening of each product.

• Adaptability and standard: Available in several standard references and various combinations (steel, stainless steel...), they adapt to most mountings and guarantee optimum reliability.

• Ease of installation: Available in retail or boxed versions, corrugated washers integrate easily into most mechanical assemblies. They are simply added between the bearing ring and the fixed part, or under the nut during tightening.

Focus on materials: steel and stainless steel

• Corrugated steel washers: Steel washers are ideal for assemblies requiring high mechanical strength. They are particularly recommended for use in dry, non-corrosive environments, while remaining economical and robust.

• Stainless-steel corrugated washers: Stainless-steel versions offer excellent corrosion resistance, making them ideal for use in damp or chemically aggressive conditions. They are often the preferred choice for sectors such as food processing and the marine industry. For example, the W61460 corrugated washer is highly prized for its technical specifications and corrosion resistance.

DIN standards and dimensions: how to choose?

The DIN (Deutsches Institut für Normung) standard establishes international standards facilitating the identification and interchangeability of parts. Each standard number specifies

• Int diameter ( inside diameter)

• Outside diameter

• Thickness or free length

• Block height to indicate maximum possible compression

It's crucial to check the level of precision required for each application to ensure a perfect fit.

For the right choice, always check the load capacity, compatibility with your existing parts and the working environment (temperature, humidity, etc.).

Common uses for corrugated washers

• Bearing assemblies : Corrugated washers are widely used to hold the inner or outer ring of bearings under pressure, especially in high-precision mechanisms. These washers are particularly useful in locations requiring axial clearance take-up, such as ball bearings.

• General mechanical engineering: They secure clamping in all kinds of structures: machine tools, transmission devices, industrial equipment...

• Automotive and aerospace: In these sectors, fine control of axial play and vibration absorption are crucial to guaranteeing component reliability and service life.
