FOR TORSION SPRINGS
3D viewer unavailable
Our Online Spring Force Tester shows you visually how much force and radial deflection (travel) in degrees you can obtain from your torsion spring safely. This is accomplished by running the spring design through our spring calculator to show true results. These numbers are true using our propietary software, Spring Creator X which gives accurate results. Please DO NOT subject your spring to go past the maximum torques or maximum deflection or travel in degrees. Please see: Note of caution on max. Safe travel (Deflection).
Max. Torque (MT)
Is the Maximum torque or force you can place on the torsion spring. If more torque is placed on the spring, the spring will deform and not return back to its original free position in degrees. Do NOT place or add more than the Maximum Torque on the torsion spring; For if you do add more force or torque than the Maximum Torque allowed, you will deform or possibly break the spring. Additionally It will not return back to its original free position in degrees and you will possibly bend the legs of the torsion spring.


Max. Travel (In Degrees)
Is the Maximum amount of safe travel or safe deflection distance in radial degrees that you can rotate or turn one leg of the torsion spring. If more radial deflection or travel in degrees is placed on the leg of the torsion spring, the spring will deform and not return back to its original free position. For this will cause a loss of Torque and possible spring failure. Please read: Note of Caution on Max. Safe Travel / Max Deflection.


Note of Caution on Max Deflection / Max.Travel on Torsion Springs
Just because there's room left to rotate the torsion spring leg further doesn't mean you should. You should NOT and CANNOT go past the Max Safe Travel distance / Max. Deflection in degrees; For if you do rotate the torsion spring leg further, you will deform or possibly break the torsion spring. Additionally It will not return back to its original free position in degrees. For this will cause a loss of torque and the torsion spring will fail to perform. Do NOT rotate the torsion spring leg past the Maximum Safe Travel Threshold.


Torque @ Degrees Traveled /Deg. Defl.
This is the amount of torque or force in: (inch-lbs or N-mm) the torsion spring leg is generating at the amount of radial degrees traveled.


Working Torque Calculation
Enter a Torque within the limits of the Maximum Torque or Enter a Degree of Travel / Deflection. The unknown value will be calculated for you when you click the tab button.


Torque 1 (T1)
Is the 1st torque force point placed on the torsion spring leg either in inch-lbs or N-mm. Within the maximum torque allowed.


Torque 2 (T2)
Is the 2nd torque force point placed on the torsion spring leg either in inch-lbs or N-mm. Within the maximum torque allowed.


Degrees of Travel / Defl.
Is the amount of radial travel in degrees the torsion spring leg rotates.


Inner diameter after deflection / travel
The inner diameter shrinks on a torsion spring when the leg rotates. The inner diameter after deflection value is your torsion spring's New inner diameter, after the torsion spring leg has rotated or traveled that distance in degrees.


Free Position (FP)
The angular free position of the torsion springs legs in a free state with no torque or force applied


Rate in-lbs/deg. Or N-mm/deg.
Torsion Spring rate, also known as spring constant, is the amount of force or energy it takes a torsion spring to travel radially or deflect one (1) degree. The torsion spring rate units are inch-pounds per degree (in-lbs/deg) and Newton-Millimeter per degree (N-mm/deg).
