This is applied to Auto parts, gym equipment, Mechanical equipment, etc. We can make all kinds of hook ring shaped tension springs with various surface treatment.

A number of different terminal devices or "hooks" are used to ensure the tensile force of the tensile spring. The working principle of the tension spring and the compression spring. When the compression spring in the compression of the reverse effect, stretching the spring in the extension or pull back when the role of. When both ends of the tension spring are pulled apart, the spring tries to pull them back together. Like a compression spring, tension springs are also used to absorb and store energy. But unlike the compression spring, most of the tensile springs are usually under a certain degree of tension, even in the absence of any load. This initial tension determines the degree of tightness of the tension spring in the absence of any load.
