The 879CS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.072" diameter hard drawn, the 879 spring design exhibits reliable strength across its 50 active coils, withstanding repeated compression cycles with a maximum load of 17 lbf without succumbing to fatigue.

We manufacture the 879 design to provide a compression spring that is 12" long at rest and provides a consistent rate of 2.6 lbs/in along its recommended maximum of 6.6" deflection. For best results, your application should fully accommodate the inner (0.606") and outer (0.75") diameters of this spring and be designed for its closed end configuration.
