Product Description:
Extension springs are helical springs that bear axial tension. Extension springs are generally made of circular cross-section materials. When not under load, the coils of the extension spring are generally tight and there is no gap between them. When the two ends of the extension spring are pulled apart, the spring will try to pull them back together to absorb and store energy. Extension springs, also known as helical extension springs, are generally of equal pitch and circular cross-section. They can be used in many occasions, such as medical respiratory equipment, motion control, medical mobile equipment, hand tools, home care equipment, shock absorption, pump springs, mechanical and electronic protective hardware, fluid control valves, mechanical aerospace components, actuators, and switch equipment.
