Compression Springs

Compression springs, also known as helical compression springs, are fundamental mechanical components. They are one of the most common types of springs that can be found in many everyday applications. These springs are designed to store and release energy efficiently when subjected to compressive forces, making them a crucial part of various mechanical systems.

There is a wide range of compression springs available, each with its own characteristics, design, and applications. The different types are listed below:

1. Regular Compression Springs
Regular compression springs, also known as straight coil compression springs, are the most common and widely used type of compression spring. Straight coil compression springs maintain a consistent outer diameter (OD) and inner diameter (ID) along their entire length, with each coil having the same diameter. The ends of these springs can be either ground or closed, featuring a 270-degree bearing surface. Unlike tapered compression springs, which have a conical shape, straight coil compression springs maintain a cylindrical shape. When compressed, they provide a uniform and linear resistance force. Regular compression springs are versatile and find application in numerous industries, from automotive and aerospace to consumer products. See Figure 1 for an illustration of regular, or straight coil, compression springs.
