Spec Sheet

Note

• As a load is applied to a torsion spring the spring's diameter will decrease, reducing the inside and outside diameters.  The spring will also grow in length.  Allow 10% clearance between the torsion spring and shaft at maximum deflection.
• The spring should wind in the direction of the coil winding.
• Ramp Torque (in-lb.) = Distance to Center of Gravity (in.) of Ramp  x Ramp Weight (lb.)
• Torsion Spring calculations.
