How to use wave spring washer
A wave spring washer is an elastic washer used for fastening components, providing reliable fastening force and stability when used correctly. Here are the steps to use a wave spring washer:
1.Select the appropriate size: Choose the right size of the washer based on the requirements and application of the fastener. Ensure that its inner and outer diameters match the bolts, nuts, or threaded shaft being used.
2.Placement: Place the washer between the fastener’s bolt, nut, or threaded shaft and the fastener component. Make sure that the wave-shaped side of the washer faces the fastener component.
3.Fastening: Use an appropriate wrench or socket wrench to tighten the bolt or nut to the specified torque value. During the fastening process, the washer will be compressed, generating axial force, providing continuous pressure, and ensuring the stability of the fastener.
4.Precautions: When using a washer, pay attention to the following:
- Avoid over-compression: Do not over-compress the washer, as it may affect its elasticity and resilience. Use the appropriate torque value and follow the installation guidelines provided by the manufacturer.
- Correct orientation: Ensure that the wave-shaped side of the washer faces the fastener component to allow it to exert the proper pressure and fastening effect.
- Non-reusability: Once a washer is compressed, its elasticity will change, so it is not recommended for reuse. When disassembling the fastener, it is usually necessary to replace the wave spring washer with a new one.
- Environmental considerations: Choose the appropriate material and coating based on the actual application environment to enhance the corrosion resistance and durability of the product.
By using the product correctly, you can ensure a secure fastening connection, prevent loosening and vibrations, and improve the overall stability of the assembly. During the installation process, be sure to follow the installation guidelines and recommendations provided by the manufacturer.
