Solon Belleville Springs & Washers produce high loads in small spaces and prevent bolt tension loss due to differential thermal expansion. We offer Belleville springs and washers in imperial sizes with an inside diameter from 7/64” to 2-1/2”, and outside diameters from ¼” to 5.50”.
Metric Washers
Solon's Metric Belleville Washers feature the same design and high-performance material options as imperial springs and washers, but in metric sizes. Our metric spring washers are offered in Belleville spring, flange, and DIN/disc spring options with metric sizes ranging from 4mm to 125mm.
Flange Washers
Solon Flange Washers maintain sufficient bolt tension and resultant gasket stresses in high-temperature and high-pressure applications and do not need to be retorqued once installed. Applications include flange/bonnet gasket live loading, heat exchangers, actuators, and cryogenic. Choose from several high-performance materials and a range of sizes.
DIN & Disc Springs
Solon DIN & Disc Springs are designed for use in demanding applications when a large number of deflection cycles or forces are critical. Examples include bearing assemblies, valve live loading, and heavy equipment. DIN/disc spring are available in17-7PH Stainless Steel, 301 Stainless Steel, 718 Inconel, and finished carbon steel in metric sizes from 2.5mm to 125mm.
