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.
