The Extension Spring, Regular part number 5117 from Century Spring Corp. has an outer diameter of 0.156 inches (3.96 mm) and a length of 2.8 inches (72 mm). It is made from music wire (MW) and has a suggested maximum load of 2.8 lbs (12.4 N) with a maximum deflection of 0.21 inches (5.3 mm). The spring features a double loop design and is suitable for applications requiring initial tension, which is essential for maintaining coil separation under load. This spring is designed to absorb and store energy while providing resistance to pulling forces, making it a versatile choice for various engineering applications.
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
