The 4026CS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.165" diameter spring steel, the 4026 spring design exhibits reliable strength across its 44 active coils, withstanding repeated compression cycles with a maximum load of 92 lbf without succumbing to fatigue.

We manufacture the 4026 design to provide a compression spring that is 20.3" long at rest and provides a consistent rate of 12 lbs/in along its recommended maximum of 7.8" deflection. For best results, your application should fully accommodate the inner (1.123") and outer (1.453") diameters of this spring and be designed for its closed & ground end configuration.
