Materials Used: AISI - C0175 · ALLOY - 6150, INCONEL x 750 or 718, STAINLESS: 17/7 · AND STAINLESS 301 OR 302

Nomenclature: P Ld=load in lbs. Stress=stress in (psi) lbs/sq. in x 10³ f Deflection= deflection in inches

Notes: 1. Disc Springs are tested only at f=.75h 2. Stress value at .75h is tensile at Point 2 or 3, depending on which is higher.

Important Note: Disc springs of thickness greater than .236" (6mm) will automatically be supplied with reduced thickness and bearing flats as shown in this catalog. Disc springs of thickness .236" (6mm) are supported in full and reduced thickness as shown in this catalog; please make specific request.
