How to Choose the Right Spring? /A Complete Guide to Spring Types and Selection

Common types of springs include compression springs, extension springs, torsion springs, bent wire forms, custom-shaped springs, wave springs, spiral springs, retaining rings, and leaf springs.

First, select the spring type that best suits your assembly application.
Choose the material: SUS304, SUS301, SUS316, SUS631, SWP, SWC, phosphor bronze wire, nickel-plated wire, silicon chrome alloy steel, oil-tempered wire, etc.
What load does it need to bear?
(How much force is required during compression, extension, or torsion within the working stroke?)
What is the allowable working stroke?
(Compression stroke, extension stroke, or torsion angle range.)
The distance from the spring’s free length to its maximum compressed or extended length.
Are there any space limitations?
(Wire diameter, outer diameter, length, number of coils, angle, etc.)
What is the required cycle life?
(Fatigue resistance / number of operating cycles.)
What are the environmental conditions?
(Temperature, humidity, corrosion resistance requirements, etc.)
