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.
