extension spring, tension spring, larger tension spring
Extension springs are the direct opposite of compression springs, in that they are close-coiled helical springs that extend under a pulling force. When designing extension springs consideration must be given to stress due to initial tension, stress and deflection of hooks, special coiling methods, secondary operations, and allowance for over-stretching at assembly.
We can customize any extension spring to fit your project. Life long servise and just- in- time delivery!
