A compression spring is an open-coil, helical spring that offers resistance to a linear compressive force applied to the ends. They are usually coiled at a constant diameter but they can also be coiled as a conical, barrel, or hourglass shape.



The ends of a compression spring can be open, open and ground, closed, and closed and ground. Usually the direction of wind in not critical for a compression spring but they can be wound left hand or right hand.

All of these details can be tailored to meet each specific request.
