Power springs

Our power spring is made of strip material and typically installed between an inner shaft and an external housing. The spring is usually positioned in a housing with the outer hook located around a pin or in a slot on the housing with the smallest internal diameter as specified below. It can also be placed in a larger housing, but with an associated decrease in force. We supply our power springs with a protective ring or nylon band that it removed during assembly. A power spring can be used for winding cables, hoses, safety belts and much more.
