Industrial springs are mechanical devices used in various applications to store and release energy. They are often made of durable materials such as steel and are designed to endure heavy loads and repeated use. These components work on the elasticity principle, deforming under force and reverting to their original shape once the force is withdrawn.

Finding the right type of spring is essential for optimizing the performance and longevity of industrial equipment. The choice usually depends on the specific project requirements, including load capacity, deflection range, and environmental conditions. Here are the most widely used industrial spring types and their respective applications:

1. Compression Springs

Compression springs can absorb and store energy when subjected to a compressive force. They are known for their helical coil shape and find extensive use in mechanisms where the primary load is axial compression. Their design considers factors like wire and coil diameter and the number of coils, all of which influence the spring’s behavior.

Applications of compression springs include the following:

  • Aerospace components
  • Automotive suspension systems
  • Consumer electronics
  • Industrial machinery
  • Medical devices

2. Constant Force Springs

Constant force springs, or flat spiral springs, are specialized kinds designed to exert a consistent force throughout their range of motion. Unlike traditional industrial spring types that exhibit force based on compression or extension, these components provide a steady force over their entire length. They are typically created by winding a flat material strip onto a drum, creating a spiral configuration.

Flat spiral springs are ideal in the following applications:

  • Brush springs in electrical devices
  • Cable and wire retractors
  • Measuring tapes
  • Retractable badge holders
  • Window counterbalances

3. Gas Springs

Gas springs, also called gas struts or gas lifts, provide controlled and adjustable support through compressed gas, usually nitrogen. They consist of a cylinder filled with pressurized gas and a piston that moves within the chamber. They are also widely used in various applications where controlled force, damping, and motion control are essential.

Here are some specific utilizations of gas springs:

  • Aircraft seat adjustments
  • Automated machinery
  • Ergonomic chairs
  • Hospital beds
  • Lifting mechanisms

4. Tension Springs

Extension springs are a type of coiled spring designed to resist pulling forces or tension. They operate by absorbing energy when stretched and releasing it as they return to their original, coiled position. The primary application of these components is to provide resistance to a pulling force, making them essential in various mechanical systems.

The following are common applications of extension springs:

  • Agricultural machinery
  • Consumer products
  • Garage doors
  • Industrial equipment
  • Trampolines

5. Torsion Springs

Torsion springs are helically wound springs that exert a torque or rotary force when twisted. They store and release energy as they are subjected to angular displacement. These components are employed in various applications requiring rotational force, as they provide a means to store and release energy in a controlled manner.

Common industrial applications of torsion springs include the following:

  • Automotive suspension systems
  • Clothespin mechanisms
  • Electronic components
  • Garage door mechanisms
  • Industrial machinery parts

6. Wave Springs

Wave springs are coiled devices that produce a high force in a small space. Unlike traditional industrial spring types, their flat-coiled design allows for a lower operating height while maintaining similar force and deflection characteristics. This makes them ideal for situations where a significant load needs to be supported within tight dimensional constraints.

Applications of wave springs are as follows:

  • Aerospace systems
  • Automotive components
  • Bearing preload applications
  • Electronic devices
  • Medical devices
