Extension springs supply a force by extending or pulling on them.  Typically they are cylindrical helical springs made out round wire and have either machine loops or cross center loops.  However they can be made conical, oval, barrel or virtually any other shape.  The ends can be plane, extended, square or anything else you can imagine.Our extension springs have outside diameters ranging .063”-1.25” and Free Length From .250” - 7.50”.  The loops are either cross center or machine.  If you are not able to find one of our stock items that matches your needs, we can make virtually any design.  If you need design help we have a responsive and experienced staff of engineers.
