Tension springs have a wide range of applications. They are for
example used in industrial robots and are also important components
in perambulators and door locks.
Tension springs in a wide range of variations
Tension springs are designed to give a specific pull force when
extended to a a specific length. Our tension springs have a
material dimensional range from 0.03 - 26 millimeter.
Cold coiled extension springs can be given an initial tension which
needs to be overcome before any elongation of the spring takes
place. The level of initial tension can be controlled.
Most common ends are different types of end loops and hooks, there
are also a wide range of other mechanical attachment possibilities
such as coiled in and screwed in attachments. Examples are, half
hooks, German loops, English loops, extended hooks, side hooks,
side loops, screw plugs and screw shackles.
