The A-98CS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.036" diameter hard drawn, the A-98 spring design exhibits reliable strength across its 10.5 active coils, withstanding repeated compression cycles with a maximum load of 5.4 lbf without succumbing to fatigue.

We manufacture the A-98 design to provide a compression spring that is 1.13" long at rest and provides a consistent rate of 11 lbs/in along its recommended maximum of 0.48" deflection. For best results, your application should fully accommodate the inner (0.256") and outer (0.328") diameters of this spring and be designed for its closed & ground end configuration.
