The 11988CS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.048" diameter spring steel, the 11988 spring design exhibits reliable strength across its 32.5 active coils, withstanding repeated compression cycles with a maximum load of 4.7 lbf without succumbing to fatigue.

We manufacture the 11988 design to provide a compression spring that is 6.13" long at rest and provides a consistent rate of 1 lbs/in along its recommended maximum of 4.5" deflection. For best results, your application should fully accommodate the inner (0.575") and outer (0.671") diameters of this spring and be designed for its closed end configuration.
