This spring is designed to provide an initial tension of 9 lbs (40 N) and can handle a suggested maximum load of 28 lbs (125 N). The spring is suitable for applications requiring a reliable resistance to pulling forces, with a small deflection load for secure installation. It is categorized as a double loop spring, which enhances its durability and performance in various mechanical 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
