The Cummins 138795 Compression Spring is a specialized component designed for use in commercial truck operations. This spring serves a significant role in ensuring the smooth and efficient functioning of various truck systems. To understand its importance, it is helpful to first explore the basic concept of compression springs and their general applications in mechanical systems ¹.

Basic Concepts of Compression Springs

Compression springs are mechanical devices that store energy when compressed. They operate on the principle of Hooke’s Law, which states that the force needed to extend or compress a spring by some distance is proportional to that distance. These springs are typically made from materials like steel, stainless steel, or music wire, chosen for their strength, durability, and resistance to deformation. The choice of material can affect the spring’s performance, including its load-bearing capacity and resistance to environmental factors ².
