Multy-turn wave spring with Shim Ends 17-7ph Carbon / Stainless Steel

Product Description

Multy-turn wave spring with Shim Ends 17-7ph Carbon / Stainless Steel


  1. Multy turn wave spring with shim ends are made of a single filament of round-edged, pre-tempered flat wire from a continuous coil. This results in uniform diameters and wave heights. They replace conventional round wire springs when space is critical, typically occupying only 1/3? of the compressed height space, while providing more deflection with the same load specifications.
  2. Multy turn wave spring with shim ends should be used for all applications requiring tight load deflection specifications where axial space is critical.


As an indispensable and important part of modern industrial production, the multy turn wave spring with shim ends plays a relatively large role, and the reason why it can play a major role in so many industries is big The reason is that it has advantages and superior performance that other products do not have. So, let’s briefly talk about what advantages it has.

  1. The multy turn wave spring with shim ends has good wear resistance and a longer service life. It has to be said that because the materials used are more particular, and repeated experiments are carried out in the process of production and processing, it can be better ensured that it is relatively wear-resistant, even if it is used for a long time, its The appearance will not be affected in any way.
  2. The multy turn wave spring with shim ends has good high-temperature resistance and is more adaptable to the environment. It is very worth mentioning that even when working in a very high-temperature environment, it can maintain its performance at a high level without being affected.


After precipitation and hardening, 17-7 appears blue, brown, or silver as a result of open-air heat treatment, while controlled air heat treatment provides bright colors. Corrosion resistance similar to 302 stainless steel, this alloy is used almost exclusively in multy turn wave spring with shim ends, but offers high tensile and yield strengths for special retaining ring applications. In fatigue and high-stress applications, 17-7 performs better than even the best high-grade carbon steels. The spring properties are achieved by precipitation hardening from the C state to the CH900 state. As a result, the material can withstand temperatures of 650°F (343°C) without loss of spring properties. The 17-7 PH CH900 temper exhibits magnetic properties similar to high-carbon steels.

The use of 17-7PH stainless steel to make springs can meet the special performance requirements of some products. Therefore, its materials and manufacturing processes are special.

A multy turn wave spring with shim ends is a type of mechanical spring used for various engineering and industrial applications. Let’s break down the key components and features of this type of spring:

  1. Multi-Turn: A multy turn wave spring with shim ends has multiple coils or turns. Each turn acts as a separate spring element, and these turns are connected in series. This design allows for greater deflection and flexibility compared to a single-turn spring.
  2. Wave Spring: A wave spring is characterized by its wavy or corrugated shape. This design allows the spring to compress and expand while maintaining a nearly constant load or force throughout its range of motion. This is in contrast to traditional coil springs, which have a variable force based on their compression.
  3. Shim Ends: Shim ends are flat or thin disc-like components attached to the ends of the multy turn wave spring with shim ends. They serve several purposes:
  • Preventing Over-Compression: Shim ends can help limit the compression of the spring within a specified range, ensuring that the spring is not compressed beyond its intended design limits.
  • Providing a Flat Surface: Shim ends create flat, stable surfaces for the spring to rest against, making it easier to install and integrate into a system.
  • Acting as Retainers: In some cases, the shim ends may act as retainers to hold the spring in place within an assembly.

Multy turn wave spring with shim ends are commonly used in applications where space is limited, and a compact, consistent force is required. Some common applications include:

  • Sealing: They are used in seals and gaskets to maintain a constant force to prevent leaks.
  • Bearings and Assemblies: These springs can be used to preload bearings or to provide a controlled force in various mechanical assemblies.
  • Electronics: They are used in electronic devices to ensure proper contact force in connectors and switches.
  • Automotive: In automotive applications, they can be used in various mechanisms, such as clutch systems, transmissions, and suspension components.

The design of these springs can vary based on specific application requirements, and they come in different sizes, materials, and load capacities to suit a wide range of needs. The use of shim ends is just one of the ways to customize the functionality of the multi-turn wave spring to meet the demands of a particular application.

Certainly, let’s continue discussing multy turn wave spring with shim ends:

  1. Material Selection: The choice of material for a multi-turn wave spring with shim ends depends on the application’s specific requirements. Common materials include carbon steel, stainless steel, and exotic alloys like Inconel. Material selection is crucial as it affects factors like corrosion resistance, temperature resistance, and durability.
  2. Load and Deflection Characteristics: Multi-turn wave springs are designed to provide a consistent force (load) over their deflection range. Engineers and designers can select the appropriate spring with the desired load and deflection characteristics to suit their application’s needs. By adjusting the number of turns, wave amplitude, and other factors, the spring’s performance can be fine-tuned.
  3. Installation and Handling: Proper installation of multy turn wave spring with shim ends is crucial to ensure their correct functioning. The shim ends provide flat surfaces for mounting and positioning. It’s important to follow manufacturer guidelines for handling and installing these springs to avoid damage or misalignment.
  4. Customization: Manufacturers can customize multi-turn wave springs with shim ends to meet specific design requirements. This includes altering the dimensions, number of turns, and wave patterns, and adding additional features, such as coatings for enhanced corrosion resistance.


  • Compact Design: Multy turn wave spring with shim ends are space-efficient and can fit into tight spaces.
  • Consistent Load: They provide a nearly constant load/force throughout their range of deflection.
  • Reduced Vibrations: They can help dampen vibrations and reduce noise in mechanical systems.
  • High Load Capacity: Despite their compact size, multi-turn wave springs can handle significant loads.
  • Cost-Effective: Their design allows for material savings compared to traditional coil springs.


  • Automotive: Used in clutch and transmission systems, suspension components, and engine assemblies.
  • Aerospace: Found in aircraft landing gear and various mechanical systems.
  • Medical Devices: Used in devices requiring precise and consistent forces.
  • Industrial Equipment: Common in machinery and equipment where space is limited.
