DID’s Patented X-Ring construction reduces friction by twisting between the side plates instead of being squashed, the twisting action of the X-Ring disperses the pressure and minimizes powerloss.
The X-Ring’s four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring.
X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain
