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.
