Heavy Duty X-Ring Chain 525 ZVM 128 Link


D.I.D's X-Ring is about 50% lower friction and delivers 50% to 100% longer wear resistance.

D.I.D X-Rings have 1.8 greater durability than conventional O-Rings.

D.I.D X-Ring reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers' modified O-Rings have squashed points that increase friction. The twisting resilience of the X-Ring's four sections greatly increases 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.
