Spring washers

In various types of mechanical connectors, bolt loosening prevention is a very important link. There are many ways to prevent bolt loosening, including the use of spring washers.

Spring washers are a subtype of washers that are conical in shape to prevent them from being placed flush with the surface without load. They are designed to provide spring force and absorb shock by providing axial loads that offset vibration. Therefore, spring washers can greatly prevent fasteners from loosening over time.

For commercial heavy-duty axles, spring washers are widely used, with more than 50% of bolts using spring washers to prevent loosening.

Main materials and specifications of spring washers

Spring washers are mainly made of stainless steel and carbon steel, usually 65MN spring steel or 70# carbon steel, 3Cr13, stainless steel materials SUS304 or SUS316, and phosphor bronze materials.

Commonly used spring washers are M3, M4, M5, M6, M8, M10, M12, M14 and M16. The national standard GB/T 94.1-2008 for spring washers stipulates the technical conditions for elastic washers with specifications of 2-48mm.

Advantages of spring washers

1. Good sealing performance: Spring washers are made of elastic materials, can automatically adjust the sealing force under high pressure, and have excellent sealing performance.

2. Excellent pressure resistance: The spring washer structure is specially designed to resist high-pressure extrusion, ensuring that the seal will not be squeezed and deformed during use.

3. Corrosion resistance and high temperature resistance: Spring washers are generally made of materials such as polytetrafluoroethylene, elastomers or stainless steel, with excellent corrosion resistance and high temperature resistance, suitable for sealing needs in various harsh environments.

4. Easy installation: The spring washers have regular shapes and are easy to install, and do not require professional technicians to install.

5. Low cost: Compared with other seals, spring washers are made of stamping technology with relatively low manufacturing costs, but the use effect is very significant.
