Half Hook Huge Long Extension Springs Right Direction Alloy Steel
|Material||Alloy steel 60Si2Mn|
|Hook type||Machine half hook|
Using CNC spring coiling machines, we can produce custom extension
springs with wire diameters from 0.08mm to 35mm in the way of cold wounding and hot wounding.
Most extension springs are wound with initial tension. This is an
internal force that holds the extension spring's coils together.
The measure of the initial tension is the load necessary to
overcome the internal force and begin coil separation. Unlike a
compression spring that has zero load at zero deflection, an
extension spring can have a reload at zero deflection . This
built-in load, called initial tension, can be varied within limits,
decreasing as the spring index increases.
Our extension springs are available with different end
configurations to facilitate the attachment to components being
acted upon. End configurations that we offer include full
loop,machine hook,coned end with swivel hook or bolt,crossover hook
and custom shaped hook.
Applications for extension springs include automotive interiors and
exteriors, garage door assemblies, appliances,furniture,engineer
machines,washing devices, farm machinery as well as thousands of
other uses. XULONG’s extension springs come in a wide array of
sizes, from small medical devices to off-road machinery brake
springs and marine container.
