Product Description

Custom High Torque Double Hook Lightweight Coil Tension Springs



It is a spiral spring that bears axial tension. Tensile springs are generally made of circular cross section materials. In the case of no load, the stretch spring between the coil and the coil is generally tight without clearance.Tension spring, suitable for high and low temperature, corrosion resistance and other working environment, materials mainly include stainless steel spring line, carbon steel wire, oil quenching and tempering alloy spring line, high and low temperature alloy spring line.

Tension Spring
The rings are tightly wrapped so that they can be stretched by force, and each end is wound in a Loop. The following is the necessary information for a stretch spring:
(1) free length :(a) total length, (b) total length of the loop, (c) length inside the hook loop.
(2) control diameters :(a) outer diameter, (b) inner diameter, (c) inner diameter of casing.
(3) Wire size "wire diameter".
(4) Materials (type, grade).
(5) number of turns :(a) total number of turns and (b) right or left.
(6) Terminal form.
(7) load in the hook.
(8) Load rate, deflection, pounds per inch.
(9) Maximum stretching length.

1. Which spring is used in mechanical toys?
Spiral springs are used in watches and toys. Whereas torsion springs are used in places where a static position is required to be maintained against impact and load fluctuation.

2. How many types of springs are there?
Again, there are three classes of springs: linear (or constant rate) springs, variable rate springs, and constant force springs.

3. What is extension and compression?
Extension Spring. A compression spring is meant for shortening its length under the action of external force. An extension spring is meant for increasing its length under the action of external force.

4. Are torsion springs safer than Extension springs?
Torsion springs are safer than extension springs and often last twice as long. Coating a torsion spring makes it last even longer than a regular torsion spring.

5. Can you open a garage door with a broken spring?
Garage doors with broken springs should not be opened. Doors in this condition can be difficult to lift because the garage door opener loses the support springs provide in lifting and lowering the door.

6. Does a garage door need 2 springs?
Doors with extension springs should always have two springs. The pair work together to provide a counterweight to the door. If one of your garage door springs breaks or is in poor condition, replace both springs
