Product Description

Custom High Precision Nested Wave Springs with Shim Ends Wave pad manufacturers


  1. A wave spring, also known as a coiled wave washer spring or microwave spring, is a spring made up of pre-hardened flat wire in a process called on-edge coiling (also known as edge-winding). During this process, waves are added to give it a spring effect.
  2. MultiWave springs should be used for all applications requiring tight load deflection specifications where axial space is critical.
  3. Capabilities: Spring thickness from 0.15mm to 0.7mm (0.006¡±to 0.0276¡±)
  4. Spring outside dia. from 12mm to 60mm(0.472¡±to 2.36¡±)

Please offer me your drawing or sample, so we can produce it according to your request.

Spring wave washer anti-loose principle

The anti-loosening principle of the spring wave washer is that after being flattened, the spring wave washer will generate a continuous elastic force, so that the threaded connection pair between the nut and the bolt will continue to maintain a frictional force, generating a resistance torque to prevent the nut from loosening. At the same time, the sharp corners at the opening of the spring wave washer are respectively embedded in the surface of the bolt and the connected part, thereby preventing the bolt from rotating relative to the connected part.

The main function of the spring wave washer is to protect the surface of the connector and prevent the surface of the workpiece from being scratched when the bolt and nut are tightened; the spring wave washer is anti-loose. However, for some important connections, such as places that rely mainly on compression to generate frictional force to transmit power, spring pads cannot be used, and the rigidity of the connection is reduced, which is prone to accidents.

The basic function of the spring wave washer is to give a force after the screw and bolt are tightened to prevent loosening. Increase the friction force between the screw bolt and the material, so that the material tightens the material in the vibration and prevents the loosening between the screw bolt and the material. Simply put, the role of the spring washer is to play the role of a protective measure.

The difference between flat washers and spring wave washers

The elasticity of the ordinary spring washer is relatively large, and the anti-loosening effect is obvious and reliable by virtue of its large elastic force and the frictional force of the oblique opening. It is used for the anti-loosening occasion of the mechanical structure of the channel. The wave spring washer presses the connected parts by its elastic deformation to prevent loosening, The wave washer has a small elastic force, and the force is uniform, and the surface of the connected parts is not damaged. It is usually dedicated to occasions where general anti-loosening is required. For example, this type of washer is used to prevent the link between the two blades of hair clippers from loosening.

Flat washers are generally used to increase the contact area between parts. Its principle is not only to reduce the damage of parts by increasing the contact area between parts but also to reduce the pressure between the nut and the equipment. It is an umbrella-like existence. Since the flat washer has no buffer, it cannot act as a shock absorber. In addition, compared with the spring washer, the flat washer has no anti-loosening function. The spring wave washer is different. The spring washer can play a good anti-loosening and anti-seismic effect according to its own elastic advantages.

When the strength of the connected parts is low, use flat washers or flange bolts to increase the contact area. When there is vibration, pulse, and large fluctuations in the temperature of the medium, spring wave washers must be used. The spring wave washer can increase the preload and prevent loosening, while the flat washer does not. However, due to the influence of material processes and other factors, the spring wave washer will break. Even so, some important connections, such as places that rely mainly on compression to generate frictional force to transmit power, cannot use spring pads, which reduce the rigidity of the connection and are prone to accidents.

Factors to consider when choosing a wave washer

Wave washers are mechanical devices that are used to provide a preload on a fastener or to maintain the position of a component. When choosing a wave washer, the following factors should be considered:

  1. Material: Wave washers are typically made of spring steel, stainless steel, or other durable materials. You should choose a material that is compatible with the application, and that can withstand the environmental conditions in which the washer will be used.
  2. Load capacity: The washer must be able to withstand the forces that will be exerted on it during normal operation.
  3. Corrosion resistance: If the washer is used in an environment where corrosion is a concern, it should be made of a material that is resistant to rust and other forms of corrosion.
  4. Temperature range: The washer should be able to operate within the temperature range of the application.
  5. Inner and outer diameter: The inner and outer diameters of the washer should match the dimensions of the fastener or component on which it will be used.
  6. Wave height and number of waves: The wave height and number of waves will affect the force produced by the washer. Choose the one that fits your application’s needs
  7. Brand reputation: It is always a good idea to consider the reputation of the manufacturer when choosing a wave washer, so you can be sure you are getting a quality product that meets your needs.
  8. Compliance: It is important to check if the wave washer is compliant with any relevant industry standards or regulations, such as those set by ASTM, ASME, or ANSI.

By considering these factors, you can be sure to select a wave washer that is well-suited to your application and will provide reliable performance over time.
