Wave Springs

Wave springs originated in the United States in the 1970s and were initially developed specifically for aerospace and military applications. Compared to traditional round-wire coil springs, they offer two key advantages: they can reduce the working stroke by approximately 50% and lower weight by up to 70% while supporting the same load. Early wave springs were stamped from thin steel sheets, a method that incurred high tooling costs, long lead times, and was limited to single-layer designs. Modern manufacturing utilizes specially wound thin steel strip, enabling the production of both single-layer and multi-layer wave springs in coiled or pre-flattened forms. This process also minimizes radial expansion during compression, preventing interference with surrounding components.

Variants
Single-turn wave springs, multi-turn (stacked) wave springs, Shim ends wave springs, crest-to-crest wave springs, nested wave springs, round-wire wave springs.

Application Fields
Since the 21st century, wave spring applications have expanded across various industries. Key sectors include aerospace, precision machinery, hydraulic sealing, high-performance motors, and automotive components.
