Extension springs are available in different sizes. You'll need to choose the right size for the load-bearing application with which you intend to use it. Most extension springs feature several measurements. By checking these measurements, you''ll know whether it''s the right size.

Outside Diameter

You should consider the outside diameter when shopping for an extension spring. The outside diameter is exactly what it sounds like: the diameter of an extension spring measured from the outside of the body.

Inside Diameter

Extension springs have an outside diameter, and they have an inside diameter. The inside diameter is smaller than the outside diameter. It represents the diameter of an extension spring measured from the inside of the body.

Wire Diameter

The wire diameter of an extension spring represents the diameter of the wire from which it''s made. Extension springs are made from wire. But the size of their respective wire may vary. Some extension springs are made from thick wire, whereas others are made from thin wire. By checking the wire diameter, you''ll know the size of an extension spring''s wire. The wire diameter is the diameter of the wire.

Body Length

The body length of an extension spring represents the length of its coiled body minus the hooked ends. Most extension springs have an integrated hook or loop on both ends. Using these hooked ends, you can connect extension springs to machines or equipment. The body length doesn''t take into ccount these hooked ends. It''s simply the length of an extension spring''s coiled body without the hooked ends.

Free Length

The free length of an extension spring represents the total length. It includes the length of the coiled body plus the hooked ends. You can calculate the free length by measuring the entire length of an extension spring, from one end to the other end. -弹簧展-2024第二十四届广州国际弹簧工业展览会--巨浪展览-Spring Industry Exhibition -The 24th China(Guangzhou)Int’l Spring Industry Exhibition 2024弹簧展，2024弹簧展会，2024弹簧展览会，2024弹簧机展，2024簧机展会，2024弹簧机展览会，2024弹簧设备展，2024弹簧线展，2024弹簧线展会，2024弹簧线展览会，2024广州弹簧展，2024钢丝展，2024钢丝展会，2024弹簧钢丝展，2024弹簧钢丝展会，2024广州弹簧机展，2024广州弹簧线材展，2024弹簧博览会，2024弹簧机博览会-Spring Industry Exhibition, spring expo, 2024 Spring exhibition, 2024 Spring expo, China Spring exhibition, China Spring expo, steel spring exhibition, steel spring expo,Spring Industry event, spring event, 2024 Spring event, 2024 Spring event, China Spring event, China Spring event 2024, steel spring event
