    Ultra-Shock-Absorbing Rubber Compression Springs

    Image of Product. Front orientation. Compression Springs. Ultra-Shock-Absorbing Rubber Compression Springs.
    Best for taking the hardest hits with minimal compression, these stout springs absorb more shock than any other spring we offer. The largest absorbs 17,000 in·lbf of energy, which is the force of a 20-lb. sledgehammer strike. 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 by inserting a fastener through the hole at the base.
    Hardness—As the durometer gets higher, the springs absorb more energy but compress less.

    Extension Springs

    Hook 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.
    Hook End—Hook into closed holes, such as hanger bolt eyes. These springs work best when kept under tension, as they're more likely to slip off than loop-end springs when tension is released. Also known as machine hook ends.
    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.
