Small Compression Springs

A small compression spring is a compact coil designed to resist compressive forces. With a diameter typically less than 0.5 inches, these springs are used to absorb energy and maintain precise functionality in tight spaces. Their role is essential in systems requiring controlled motion or force distribution.

Materials

Stainless steel is the preferred material for small compression springs due to its excellent corrosion resistance and durability. This makes it ideal for use in environments exposed to moisture, chemicals, and varying temperatures, ensuring long-lasting performance and reliability.

Applications

Small compression springs are engineered for specific tasks in industries where reliability and space efficiency are critical:

Automotive: Used in fuel systems, brakes, and clutches to manage force and motion.
Medical Devices: Integral to precision instruments like insulin pumps and surgical tools.
Electronics: These are found in battery contacts and switches, ensuring connectivity in compact assemblies.
Aerospace: Requires small compression springs features of being both high-performing and compact, particularly due to weight-sensitive environments.

Design Considerations

Key factors of a small compression spring design include load capacity, which determines the amount of force the spring can handle without deformation, and the compression length, which defines its working range. The number of coils, wire diameter, and end configuration—whether closed, open, or ground—directly influence the spring’s stiffness and how it integrates with the surrounding components.
