A Closer Look at Spring Types and Their Uses

Springs are coiled, helical, or flat components that are designed to provide tension, compression, or force to support the smooth operation of many mechanical systems. Understanding the differences between their diverse types helps users select the appropriate solution for each application. This blog explores some of the most common spring options, their designs, and the unique benefits they offer.

What Are Compression Springs and How Are They Used?

Compression springs are designed to resist compressive forces, meaning they compress when a load is applied and return to their original shape once it is released. They typically feature a cylindrical shape, although variations like conical and barrel-shaped designs exist to suit specific needs. In automotive suspension systems, compression variants absorb shocks from uneven road surfaces, ensuring a smoother ride by minimizing vibrations that would otherwise transfer to passengers and vehicle components. Without them, cars and trucks might experience significant wear on their frames, leading to faster degradation of parts. Likewise, in medical devices like syringe pumps, compression springs regulate the movement of a plunger to guarantee controlled delivery of fluids or medication.

How Do Extension Springs Work and Where Are They Applied?

Extension springs are helical coils that can generate a substantial amount of force when stretched. These types are easily recognizable by the hooks or loops at their ends, which allow them to attach to components that need to be pulled together. When a garage door is pulled down, extension options store energy that will enable them to help lift it when opened. This lessens the amount of manual effort required or–in automated systems–reduces strain on the motor. Meanwhile, on trampolines, extension springs stretch and contract with each bounce, providing the necessary rebound force to optimize safety and enjoyment for users.

What Are Torsion Springs and When Are They Useful?

Torsion springs are usually coiled tightly and feature two arms at their ends, which rotate around a central axis. When one arm moves, the spring exerts a rotational force to return to its neutral position. In door hinges, torsion variants allow doors to close automatically by twisting under tension when the door is opened, then releasing stored energy to return it to its closed position. This is particularly beneficial in public spaces, where automatic closures help maintain building security and climate control.

Where Are Constant Force Springs Applied?

Constant force springs are distinct from other types due to their flat strip design, which uncoils evenly from a preloaded state. In window counterbalances, these types make it easier to raise or lower windows by providing consistent support throughout the motion. Meanwhile, in retractable seat belts, these components manage a belt’s extension and retraction by maintaining steady tension that prevents slack.

How Are Gas Springs Different and Where Are They Applied?

Gas springs consist of a cylinder and a piston, along with nitrogen gas sealed inside to generate force as a piston moves. In automotive hatchbacks, gas springs assist with lifting heavy trunk lids and holding them in place without requiring manual effort. Likewise, in office chairs, these components allow for smooth adjustments that precisely correspond with a user’s preferred height.
