The 66147SCS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.017" diameter 316 stainless steel, the 66147S spring design exhibits reliable strength across its 6.25 active coils, withstanding repeated compression cycles with a maximum load of 1.19 lbf without succumbing to fatigue.

We manufacture the 66147S design to provide a compression spring that is 0.25" long at rest and provides a consistent rate of 19.5 lbs/in along its recommended maximum of 0.061" deflection. For best results, your application should fully accommodate the inner (0.091") and outer (0.125") diameters of this spring and be designed for its closed end configuration.
