    Color-Coded Die Springs

    With the Raymond color code, you'll always grab the die spring with the right load rating. The chrome-silicon steel is stronger than spring steel and handles repeated stress for longer periods of time. Rely on these springs for high-volume jobs, such as stamping and injection molding. A powder coating prevents rust in wet environments. The closed, ground ends create a flat surface that balances your load, even as it moves.

    Extension Springs

    Loop End

    The farther you stretch these springs, the harder they pull to bring the two ends back together. They're commonly used to tension cable, return an air cylinder to its starting point, or hold a door closed.
    Loop End—The most secure attachment method. With fully closed loops, there's no risk of slipping off.
    Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.
    Minimum Load—The amount of force required to start extending the spring.
    Maximum Load—The amount of force required to fully extend the spring.
