    Shock-Absorbing Rubber Compression Springs

    Image of Product. Front orientation. Compression Springs. Shock-Absorbing Rubber Compression Springs.
    Absorb shock from hard hits and soften the stop. All of these springs deliver a gentler stop than our ultra-shock-absorbing rubber springs, thanks to a large hollow center that allows them to compress to one-third of their length. Made from a polyester/rubber blend, they stay springy longer than metal and plastic springs—with documented cases up to one million cycles. They also stand up to oils, fuels, and mild cleaning solutions.
    Secure using one or both holes on either side of the spring.
    Hardness—As the durometer gets higher, the springs absorb more energy but compress less.

    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.
