OEM Available Retractable Constant Double Hook Extension Spring For Automatic Equipment
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.

equipment, hand tools, home care equipment, shock absorption, pump
springs, mechanical and electronic protective hardware, fluid
control valves, mechanical aerospace parts, actuators, switchgear.
