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.

Long-Life Rubber Compression Springs
 |
When longevity matters most, these springs deliver. Made from a polyester/rubber blend, they stay springy longer than metal and plastic springs—with documented cases up to one million cycles.
Flanges on the ends create a flat mounting surface.
Hardness—As the durometer gets higher, the springs absorb more energy but compress less.

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.

Rubber Die Springs
 |
Our longest-lasting die springs. Polyurethane rubber balances strength, durability, and flexibility better than metal springs. When overstressed, these springs don't shatter, so they prevent injury and equipment damage. The rubber dampens vibration and won't creak or rattle. They also stand up to oil, fuel, and mild detergents without breaking down.
Deflection @ Maximum Load—The percentage represents how much a spring compresses from its original length.
