The 73661CS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.593" diameter oil tempered, the 73661 spring design exhibits reliable strength across its 12 active coils, withstanding repeated compression cycles with a maximum load of 1064 lbf without succumbing to fatigue.

We manufacture the 73661 design to provide a compression spring that is 14" long at rest and provides a consistent rate of 222 lbs/in along its recommended maximum of 4.8" deflection. For best results, your application should fully accommodate the inner (3.72") and outer (4.906") diameters of this spring and be designed for its closed & ground end configuration.
