Product Description

OEM Available Retractable Constant Double Hook Extension Spring For Automatic Equipment


Extension/Tension Spring

Referred to as tensile spring, also known as tension spring, is a spiral spring bearing axial tension, tension spring is generally manufactured with circular section raw materials. In the absence of load, the coil and the coil between the tension spring are generally tight and there is no gap. There is a kind of spiral tension spring, generally equal pitch, the cross-section is mostly round, they can be used in many occasions, such as production, manufacturing, assembly, experiment, product development, maintenance.

A number of different terminal devices or "hooks" are used to ensure that the tension source of the stretch spring is maintained. A stretch spring works the opposite of a compression spring. A compression spring acts in reverse when pressed, and a stretch spring acts in reverse when stretched or pulled. When the two ends of the stretch spring are pulled apart, the spring tries to pull them back together. Like compression springs, stretch springs absorb and store energy. But unlike compression springs, most stretch springs usually operate with some degree of tension, even without any load. This initial tension determines how tightly the stretch spring is wound without any load.
