Product Description
Waved Springs: Design and Applications of SUNZO Precision Elastic Components
A waved spring (wave spring) is an elastic component formed by peaks and valleys on a continuous metal ring, providing axial force through the elastic deformation of the wave profile, with excellent elastic properties and impact resistance. In applications requiring fine force control, wave springs deliver low spring stiffness and stable, precise axial preload, and are therefore widely used in precision machinery, aerospace, hydraulic sealing, and high-end motor manufacturing.
Wave Springs: Structure and Working Principle
Wave springs are made from a continuous metal strip, with periodic peaks and valleys precisely formed along the strip. When force is applied along the axial direction, the waves deform elastically, generating the required preload or support force. Compared with coil springs, wave springs have low axial height and distribute load more evenly, offering a more compact design within the same axial space, which suits components sensitive to installation space.
Depending on structure and layer count, wave springs can be divided into single-layer closed, multi-layer nested, and open-end types. Single-layer closed wave springs feature a simple structure and easy installation and are a widely used form; multi-layer nested types achieve higher load capacity through parallel stacking.
Core Characteristics: Low Stiffness and Stable Preload
A prominent feature of wave springs is their ability to provide stable, precise axial preload with low spring stiffness. For applications requiring fine force control, such as seal preload, bearing positioning, and valve return, wave springs maintain force stability over small deflection changes, reducing the impact of assembly tolerances and operating fluctuations on system performance.
In addition, wave springs offer good elastic recovery and impact resistance, adapting to harsh conditions such as vibration, shock, and temperature changes, which helps extend component life and improve operational stability.
Typical Applications: Covering High-Precision and Demanding Conditions
Wave springs are used across multiple high-precision and demanding industries:
- Precision machinery: bearing preload, gear positioning, and mechanism return, providing stable axial force and reducing assembly error effects
- Aerospace: seal preload and weight-optimized designs in flight control and hydraulic actuation systems, meeting stringent reliability requirements
- Hydraulic sealing: continuous preload for sealing interfaces in hydraulic cylinders and valve assemblies, helping to maintain system pressure integrity
- High-end motors: bearing preload and end-cap support, improving operational stability and noise performance
Material Portfolio: 1074, 65Mn, 60Si2MnA, and SUS304
The material of a wave spring directly affects its elasticity, fatigue life, and corrosion resistance. Jiangsu Sunzo offers multiple material options according to application conditions:
- 1074 carbon steel (SAE 1074): balanced overall performance, suitable for general industrial spring applications, combining strength and economy
- 65Mn spring steel: a commonly used spring steel grade in China with good elasticity and fatigue performance, suitable for general machinery
- 60Si2MnA alloy spring steel: a silicon-manganese alloy spring steel with good strength and hardenability, suitable for applications with higher stress and impact
- SUS304 stainless steel: good corrosion resistance, suitable for humid, chemical, and other environments requiring corrosion resistance
In addition, Jiangsu Sunzo also supplies materials such as 51CrVA, 17-7PH, INCONEL718, INCONEL X-750, and NIMONIC90 to meet special requirements including high temperature, strong corrosion, and high fatigue.
Surface Treatments: Performance Enhancement on Demand
To suit different environments and functional requirements, wave springs can receive various surface treatments: phosphating improves lubricity and corrosion protection, Dacromet coating significantly enhances salt spray resistance, PTFE impregnation reduces the coefficient of friction, and electroless nickel plating provides a uniform corrosion-resistant layer. Jiangsu Sunzo recommends suitable surface treatment combinations according to media, temperature, and assembly requirements to improve the overall performance of wave springs in target conditions.
