What are compression springs?

Compression springs, also called coil springs, are the most classic versions of mechanical springs. As the name suggests, these types of springs get compressed under heavy load but generate a resisting force that pushes back against the load to return to it’s normal, uncompressed position.

Types of compression springs

Compression springs come in different sizes, which often determine their application as well. The most commonly used types of compression springs include:

• Small compression springs: These types of compression springs are very small in size and are usually called micro springs. Small compression springs are typically used in pocket-sized devices. 
• Large compression springs: These types of compression springs are specifically designed to facilitate higher spring rates. The thicker diameters of the large compression springs make them ideal for a multitude of industrial applications, such as valves, engines, turbines, printing presses, automobiles, suspension systems, and so on. 
• Heavy-duty compression springs: These types of compression springs feature much larger and thicker springs, and are ideal for sustaining higher loads. Heavy-duty compression springs are usually found in architectural structures, mining equipment, drilling rigs, aerospace engineering equipment, and industrial lifting platforms.

Applications

The versatility of compression springs makes them ideal for a diverse range of applications, ranging from everyday smaller mechanical tools to massive equipment and structures. These include:

• Ballpoint pens
• Locking mechanisms
• Precision tools
• Cars, trucks and other vehicles
• Heavy-duty industrial equipment
• Engines, turbines, and valves
• Printing press
• Electronic devices
• Medical equipment
