Flat Disc Springs
These flat rubber springs handle heavy loads, similar to Belleville disc springs, and resist oxidation, oil, and abrasion.
When stacking, separate springs with rigid flat washers. The washers must be large enough to cover the entire surface of the springs.
Deflection is the distance a spring compresses under load.
