The 75531CS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.037" diameter music wire, the 75531 spring design exhibits reliable strength across its 14.26 active coils, withstanding repeated compression cycles with a maximum load of 7.718 lbf without succumbing to fatigue.

We manufacture the 75531 design to provide a compression spring that is 1.969" long at rest and provides a consistent rate of 7.2 lbs/in along its recommended maximum of 1.072" deflection. For best results, your application should fully accommodate the inner (0.28") and outer (0.354") diameters of this spring and be designed for its closed & ground end configuration.
