Single turn gap wave washer

Product Description

Single Turn Gap Wave Spring Wire Form For Bearing Pre Tightening


Single turn gap wave springs are used for several applications, mainly designed for short deflection and low to medium forces. Technology enables to provide a dependable and accurate fit. The free ends of a gap wave spring types are allowed for the spring outside diameter grows during compression, which if constrained in a bore prevents binding of comparable stamped wave washers, this design has dramatically improved the fatigue resistance and lifetimes. Thus reduces costs effectively.

Spring washer: There is a gap in the middle, which can also be called gap wave spring, which has a certain elasticity, and can be used to prevent loosening after installation.


  1. Gap wave spring can play a good anti-loosening and anti-vibration effect;
  2. The production process of gap wave spring is simple and the manufacturing cost is relatively low, so the price will be relatively low;
  3. The product is simple and easy to install.


The gap wave spring washer is flattened when the bolt is tightened, and then its sharp corners will be embedded in the nut and the surface of the clamped object, thereby preventing the bolt from rotating in the opposite direction and preventing loosening.

Overview of single turn gap corrugated springs:

The single turn gap wave spring of Lisheng Company has excellent performance and can achieve the best elastic compression spring products in the narrow space. After repeated tests, it has produced a variety of flat wire corrugated pitch wave springs to meet customer needs. The single turn gap wave spring can be divided into opening and closing. In addition, the company can also design and produce various non-standard single turn gap wave springs. In view of the fact that there is no unified multi-layer single-layer gap wave spring standard in China, the company produces or designs various multi turn single turn gap wave springs according to customer requirements.

Advantages of gap wave spring

Gap wave springs, also known as wave washers or wave springs, have several advantages over other types of springs. These include:

  • Space savings: Gap wave springs have a smaller physical size compared to other types of springs, making them ideal for applications where space is limited.
  • Low spring rate: The spring rate of a gap wave spring is lower than that of a traditional coil spring, allowing for more precise load control and less force required to compress the spring.
  • Low profile: Gap wave spring are low profile, that means they are thinner than coiled springs, and can fit in tight spaces.
  • Consistent force: Gap wave springs provide a consistent force over a wide range of deflections, making them ideal for applications where consistent performance is required.
  • Reduced noise: Gap wave springs generate less noise than other types of springs, making them ideal for applications where noise reduction is important.
  • Cost-effective: Gap wave springs are typically less expensive to produce than other types of springs, making them a cost-effective option for many applications.

Application of single turn gap corrugated spring:

Single-layer gap wave springs, also known as single turn gap wave springs or wave washers, are processed from metal steel strips into thin circular rings. Single turn open wave springs are elastic elements with several peaks and valleys. It is usually used in the occasions where the space is narrow, the load and deformation are not large, the spring stiffness is required to be small, and the axial preload needs to be applied. According to the current conditions of use and stress conditions, the geometric dimensions and related processing requirements of the single-layer open wave spring can be determined by using the computer-aided design system independently developed by the company. The unique feature of Lisheng single turn open wave spring is that in terms of workload, the space occupied by Lisheng single-layer open wave spring is relatively small. In fact, a single layer of open wave springs can reduce the size and weight of components by as much as 40% to 50%.

Application examples of gap wave springs

1. Bearing preload

Wave springs can be used in bearing preload devices. The wave spring always provides a suitable elastic force during the operation of the bearing. The elastic force is mainly used to eliminate the movement and vibration of the bearing. At the same time, it can also reduce the working noise of the bearing, which greatly improves the smooth operation and service life of the bearing.

2. Electrical connector

The wave spring is used for the buckle and cap connection of the electrical connector. During the compression process of the wave spring, there is always a locking force between the card pin and the card slot of the electrical connector, so that the two are tightly connected without slipping out.

3. Release bearing

The elastic element flexibly couples the release bearing with the release sleeve. During the engagement process of the release bearing and the clutch, the elastic element in the self-aligning release bearing produces elastic deformation or radial slip due to the additional radial force generated by the eccentricity, realizing the automatic comparison between the rotation axis of the release bearing and the rotation center of the clutch middle.

4. Water pump seal

The leakage of the water seal can be effectively reduced by utilizing the advantages of wave springs with elastic force, preload, compensation and buffering characteristics, and the advantages of wave springs with uniform and stable elastic force and good follow-up type. Moreover, the specific pressure of the spring of the water seal will be greatly reduced, which can also effectively reduce the amount of friction wear and improve the durability of the water pump.


Single turn gap wave springs are used in a variety of applications and are primarily designed for short deflections and low to medium forces. Technology can provide a reliable and accurate fit. The free end of the gap wave spring allows the spring outer diameter to grow during compression, which if confined in the hole would prevent a stamped wave washer-like bond, this design yields significant improvements in fatigue strength and life. Thereby effectively reducing costs.

A gap wave spring is a type of wave spring that is used to absorb and dampen shock and vibration. It is made up of a series of metal discs, or gaps, that are connected together. When the spring is compressed, the gaps close up, and when it is released, the gaps open up again. This allows the spring to absorb and dissipate energy quickly. Gap wave springs are often used in vibration and shock-absorbing applications, such as in engines, gearboxes, and other machinery.
