Spring washer: All you need to know

Spring washers, also known as Belleville washers, are crucial mechanical components for ensuring stability and reliability in a variety ofassembly systems. Designed to handle dynamic or static loads, they offer constant strength and high resistance thanks to their conical shape and unique elastic properties.

What are 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 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 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 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 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 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 the most common applications for spring washers?

These washers are frequently used in :

• Electrical connections requiring stable contact.

• Mechanical fasteners to absorb vibrations.

• Industrial mechanisms subject to high pressure.
