Garage Door Spring Constant

This calculator will determine the spring rate related to a torsion spring from basic geometry and material data input.

Garage door spring constant. Default units are shown in inches etc however si metric can be used. Most commonly it has a three pronged support system with a center and two end bearing plates at either end. Stiffness is linear over most of the range of operation with a spring constant of approximately 265. If its endpoints in a clockwise direction then it is a left wound spring and vice versa.

The torsion spring is mounted to the header wall above the garage door. So how do you tell if a garage door spring is a left or a right spring on your garage door. Regardless of the type your garage springs are responsible for helping the door raise and lower. Based on the facts if we divide 15 000 by 3 we get samwise garage door spring s life expectancy which is 5 000 days or 13 years and 7 months.

Two p528 springs one on each side of the door can handle a 105 lbs. Samwise the brave has a sectional garage door and its torsion spring is a 15 000 cycle spring. Check where the end of the spring is pointing and identify the wind direction. On average samwise takes his little pony for a ride in the shire 3 times per day.

Door with an initial tension of 165 lbs. When the garage door is lowered the springs gain tension. After passing through the second set ofpulleys the two cables are joined together by a carabiner attached to the upper end oftwo garage door springs mounted in series. Garage door torsion springs 1 75 pair with non slip winding bars coated torsion springs with a minimum of 10 000 cycles 0 207x1 75 x24.

This rule is only inapplicable if your garage door utilizes a reverse spring system.
