Wave spring washer

What are wave spring washers?

Spring washers are metal discs with a curved surface, manufactured to DIN standards- a benchmark in the field of mechanical components. Their special design reduces vibration, extends the life of surrounding components and secures fasteners.

These washers are often used in applications where high force is required in a confined space, thus providing a spring function. Their operation is based on a spring effect, enabling them to provide constant pressure in a variety of situations.

What are the characteristics of wave spring washers?

Spring washers are ingeniously designed to deliver high force in a short stroke, making them ideal for applications requiring high force in a small space. Generally made from steel, they are available in a range of diameters, from 4.5 to 29 mm, to suit a variety of needs.

The operation of a spring washer relies on its unique conical design, which offers resistance when compressed, generating the spring effect. The force produced by the washer depends on several factors: its diameter, thickness and open height. A crucial parameter to consider is the flattening load, i.e. the maximum load the washer can support without plastic deformation.

These washers are particularly useful in constructions where high force is required in a minimum of space. They are also used in applications such as torque limiters, spring elements and springs with almost linear characteristics.

How do wave spring washers work?

In terms of operation, spring washers can be stacked in parallel or in series to obtain the desired force and stroke. When stacked in parallel, the total force is the sum of the individual forces, while the total stroke remains the same as that of a single washer. On the other hand, when stacked in series, the total force is equivalent to that of a single washer, but the total stroke is the sum of the individual strokes.

In short, spring washers are versatile and essential products for a variety of applications requiring high force in a small space. Their tapered design and ability to be stacked in parallel or in series mean that force and stroke can be adjusted to suit specific needs.

What are the advantages of a wave spring washer?

1. High strength: Thanks to their design and the material from which they are made, these washers ensure optimum performance in the face of heavy loads.

2. Versatility: They are used in a wide range ofapplications, including automotive, aerospace and mechanical engineering.

3. Built to last : Thickness and height are calculated for maximum efficiency.

4. Compatibility : Available in a range of standard sizes and DIN standards, they can be perfectly adapted to your specific needs.

What are the different types of wave spring washer?

Spring washers can be made from carbon steel, stainless steel or special materials for greater resistance to corrosion and high temperatures.

They are available in several combinations:

• Flat washers: More traditional, they are used for applications requiring low compression.

• Belleville washers: more technical, they offer better compression and are ideal for dynamic loads. The number of washers (n) in a stack influences the flexibility and overall strength of the assembly, whether in parallel or in series.

Why choose wave spring washers?

Spring washers are designed to guarantee increased safety in yourassembly systems. Their ability to absorb load variations and maintain constant pressure makes them a wise choice for sensitive mechanisms.

What's more, their use saves space thanks to their low thickness and high efficiency. At 123Roulement, we ensure top quality with washers that comply with DIN standards.

what are corrugated washers used for?

Corrugated washers are indispensable metal parts in many industrial and mechanical applications. Also known as spring washers, they are designed to take up axial play, absorb vibrations and ensure greater precision when tightening. Available in both steel and stainless steel, these washers come in a variety of dimensions(int. x ext.) and DIN standards. They distribute the clamping load evenly , ensuring optimum axis alignment and perfectly straight assemblies.

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.
