It is constructed from music wire (MW) and has a suggested maximum load of 11 lbs (49 N) with a suggested maximum deflection of 4.3 inches (109 mm). The spring is designed with an initial tension of 3.1 lbs (14 N), providing a small deflection load for secure installation. The wire diameter is 0.177 inches (4.50 mm). This extension spring is suitable for applications requiring energy absorption and resistance to pulling forces, making it a versatile choice for various engineering projects.
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
