The 51186SCS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.207" diameter 316 stainless steel, the 51186S spring design exhibits reliable strength across its 16.53 active coils, withstanding repeated compression cycles with a maximum load of 104.002 lbf without succumbing to fatigue.

We manufacture the 51186S design to provide a compression spring that is 8.071" long at rest and provides a consistent rate of 40.511 lbs/in along its recommended maximum of 2.567" deflection. For best results, your application should fully accommodate the inner (1.368") and outer (1.782") diameters of this spring and be designed for its closed & ground end configuration.
