STANDARD 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 (H) = +/-10% of the Overall Height
Deflection (h) = +/- 10% of the Deflection
Flat Load = +/-10% of the Flat Load
Torque= +/-10% of the Torque

UNITS OF MEASURE

IMPERIAL                                                                   METRIC
Dimensions = inches                                              Dimensions = millimeters
Load = pounds force                                               Load = Newton
Torque = foot-pounds                                           Torque = Newton-meters
Temperature = °F                                                     Temperature = °C
 

TORQUE CALCULATION

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