Product Introduction

Variable‑diameter special compression spring is a non‑standard custom spring. Its coil diameter changes section by section, with an extended straight‑rod end at the top instead of regular cylindrical shape. Made of premium spring steel with color zinc plating for wear and rust resistance, it fits special mechanisms where standard springs cannot be installed.

1. Multi‑section variable‑diameter design for irregular inner installation cavity

2. Extended straight‑rod end for easy positioning and penetration assembly

3. Color‑zinc surface treatment against oxidation and rust for longer service life

4. Fully customized shape, dimension and spring force according to mechanism requirements
