Cylindrically Shaped Compression Spring is an open-coil helical spring that offers resistance to a compressive force applied axially. The Compression Spring is usually coiled at a constant diameter as well as in other needed forms such as conical, concave [barrel] and convex [hourglass]. The Compression Spring is made using quality grade material to ensure fine finish and long lasting usage. Cylindrically Shaped Compression Spring is used to resist force and store energy, depending upon the application.
