What are disc spring tolerances?

The term “tolerance” refers to the amount of deviation from specification that may occur in a disc spring without compromising its performance. For Belleville disc springs, allowable tolerances for diameter, thickness, height, and load are provided in the DIN 2093 specification.

Although DIN 2093 applies only to specific limited applications and sizes, all disc springs produced by BelleFlex are manufactured in accordance with the quality and testing requirements contained in this specification.
