Wave spring classification and differentiation

What we are interested in is how to improve the performance of the spring. Breakthroughs in technology. Building the Lisheng brand for 100 years.

As a common elastic element, wave springs are used in motors, compressor hosts, fluid valves, water valves, air valves, automobile clutches, brakes, electrical connectors, bearing preloading devices and compensation devices, shaft seals, and mechanical seals. There are many types of wave springs, such as single-layer wave springs, multi turn wave springs, round wire wave springs, and wave gaskets. These wave springs are also used in different locations due to their different properties.


For example, circular wave springs are often used in clutch drives. The circular wave spring presses the circular belt through the lower gear, and the rotation of the upper gear can adjust the compression of the wave ring. Circular coils provide high force values in confined radial spaces.


In the floating gear, the crest to crest wave spring can be installed in the drag seat to carry the gear, and can be moved axially by applying light force, and at the same time, it can be self-aligned with the matching gear.


The crest to crest wave spring is also called a wave compression spring or a helical wave spring. The shape is similar to a common cylindrical coil spring. After heat treatment and surface treatment, the elasticity and toughness are excellent.

The characteristics of the crest to crest wave spring are:

  1. It is suitable for occasions with a large stroke and a small load.
  2. When bearing similar loads, at least half the space can be saved.
  3. It can reduce the overall volume of the equipment and save costs.
  4. ideal for places with limited axial space;
  5. The use requirements of different loads can be met by changing the thickness and width of the material or making two or three overlapping wave springs.


Due to the above advantages, the crest to crest wave spring has gradually replaced the conventional cylindrical coil spring on many occasions.


Product Material

The crest to crest wave spring can be made of a variety of materials, such as spring steel, stainless steel, and copper alloys. High-temperature alloys are also used on special occasions. At present, the most commonly used materials for the crest to crest wave springs on the market are carbon spring steel, alloy spring steel, etc., stainless steel 304, 316, 17-7PH, etc.


Product Application

The crest to crest wave spring is widely used in machinery manufacturing, petroleum and chemical engineering, hydraulic equipment, automobile and locomotive manufacturing, aviation industry, refrigeration engineering and other industries, such as: motors, compressor hosts, fluid valves, water valves, air valves, automobile clutches, brakes, electrical connectors, bearing preloading devices and compensation devices, shaft seals, mechanical seals, etc.


A wave spring is a common type of spring. The overlap wave spring is a single-layer wave spring with a partial overlap at the fracture. Like other wave springs, the overlap wave spring is also made of flat wire, and then undergoes different heat treatments and surface treatments. It has good elasticity and toughness in the corresponding working environment.

Nested Wave Spring

In most cases, overlap wave springs and gap wave springs perform approximately the same in an application. Both types of designs have free ends so that the outer diameter contacts the bore without friction as the spring compresses. Overlap wave springs will have a solid height greater than gap wave springs due to overlapping ends, and overlapping ends will cause the springs to wrap around each other in the package.


In addition, the overlap wave spring and gap wave spring will show differences depending on the material. In the application of one of our customers, according to the customer’s reaction, the original ordinary stainless steel wave washer is soft and will be flattened under load. I hope we can help solve it. The common stainless steel materials on the market are mostly 302 stainless steel. Compared to carbon steel, which has low spring properties, 302 stainless steel does not have the properties of carbon steel. To solve this problem, we have made improvements in raw materials. Use good stainless steel instead of ordinary 302 stainless steel. Good properties are similar to those of 302 stainless steel and can be applied to wave springs.


Traditional gap wave springs are used in a variety of applications. They function precisely and reliably in applications with short deformation ranges and low to medium levels of force. The ends of a gap wave spring are separated by a gap between the ends, which is free to move circumferentially as the spring’s outer diameter grows during compression.


Features of gap wave spring

  1. The application of short-distance deformation range and low-to-medium stress
  2. to perform precisely and consistently
  3. can be used in various applications.
