Description
Modern torsion spring torsion bars are mostly made of good elastic steel, and their forms have also changed greatly. There are hairsprings in mechanical watches, power springs in toy gyro guns, and torsion bars in tanks and cars.
Small torsion bar with large torsion, great as a shock absorber for transportation

The torsion spring is the ultimate of the variant spring, from single torsion spring to double torsion spring shaped torsion spring, and even the deformation of various torsion bars, which can be shaped according to design.
The torsion spring is one of the more complicated design principles in all spring categories, and the type changes are also quite lively, so the theory involved in design is also the most complicated. So it ’s harder to master
Necessary information of torsion spring:
(1) Free length.
(2) Control diameter: (a) outer diameter, (b) inner diameter, (c) inner diameter of casing, or (d) outer diameter of round rod passed through.
(3) Wire size "wire diameter".
(4) Materials (type and grade).
(5) Torsion force: pounds deflected to a certain angle.
(6) Maximum deflection (angle from free position).
(7) The end form.
We develop and use new materials in our High Precision Customized Small Spiral Roller Lock Double Toy Torsion Spring to minimize the negative impact of our operations on the environment and to protect the ecological environment. Our market share of our products and solutions has greatly increased yearly. Since the establishment of the enterprise, we have introduced and digested the advanced industry technology at home and abroad with a down-to-earth style and a serious attitude.
