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 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.
We have long experience of tension springs and constantly give priority to technological developments in the field. Our main competitive advantages are our wide product range, technology support, high quality and service of tension springs.
Our experience of springs for a large number of different branches and applications give you the possibility to receive the best recommendations and springs optimized for your actual application.
