The Century Spring Corp. Extension Spring, part number 80520, has a wire diameter of 0.045 inches (1.14 mm) and a free length of 1.50 inches (38.1 mm). It is constructed from music wire (MW) and is available in both standard and stainless steel (SST) finishes. The spring is designed to provide a maximum load of 12 lbs (53.4 N) with a suggested maximum deflection of 1 inch (25.4 mm). The initial tension is rated at 1.6 lbs (7.1 N), making it suitable for applications requiring a moderate resistance to pulling forces. This extension spring is ideal for projects that require reliable energy absorption and storage, with a focus on maintaining a secure installation.
Century Spring warehouses the largest inventory of high-grade extension springs in the world. Extension springs are designed to absorb and store energy as well as create a resistance to a pulling force. It is initial tension that determines how tightly together an extension spring is coiled. This initial tension can be manipulated to achieve the load requirements of your particular application. All Century extension springs are wound with an initial tension force which offers a small deflection load for secure installation "holding". The initial tension is equal to the minimum force required to separate adjacent coils. Each spring is of the constant diameter type with a variety of hook/loop styles.
Note: If the spring needed for your application cannot be found in our inventory, we can fabricate it for you. Call our Custom Spring department at 800-237-5225 or e-mail us at cust@centuryspring.c
