Solon Disc Springs (SDS)

Solon Manufacturing Co. offers a line of DIN spec parts for applications when exacting tolerances are crucial. Solon Disc Springs (SDS) conform to the DIN 2093 specifications and are RoHS complaint. These springs are effective when a large number of deflection cycles or forces are critical.

BELLEVILLE SPRING TOLERANCES
Use these tolerances as a general guide. Solon manufactures a wide variety of springs and washer sizes that meet different tolerance requirements. For actual tolerances for a specific part, contact us

ID= +1.5% of the ID Min
OD = -1.5% of the OD Max
Thickness = +/- 5% of the Thickness
Overall Height (OH) = +/-10% of the Overall Height
Deflection (h) = +/-10% of the Deflection
Flat Load = +/-10% of the Flat Load
Torque = +/-10% of the Torque

NOTE: Tolerances for custom designed Belleville springs may vary. Consult a Solon application engineer for special applications. Solon Disc Springs (SDS) follow DIN 2093 requirements. 

TORQUE CALCULATION
Imperial:
 (ft. - lbs.) = .2 x Bolt Diameter (in.) x Load (lbs.) / 12
Metric: (N-m) = .2 x Bolt Diameter (mm) x Load (N) / 1000
