G & O Spring tips – SQUARENESS TOLERANCES
PROBLEMS WITH NON-AXIAL FORCES?
Squareness of compression springs is important and, while by no means being the deciding factor for non-axial forces, a spring that stands square will perform better in this regard. All compression springs should be able to stand square without rocking and we suggest standard Squareness & Bow tolerances (intended to keep non-axial forces to a minimum) of 1° (in some cases this can be as little as 1/2°).
Squareness (E1) is difficult to accurately measure without a specialist optical system and we recommend that tolerances should ideally be shown on the drawing as a maximum dimension and not in degrees. To aid you with the calculations (where your legacy drawings show squareness in degrees) we have included a handy little calculator so you can check your springs comply.VISIT OUR SQUARENESS CALCULATOR
