What makes the XW-ring better than the O-ring?
XW-ring seals feature multiple sealing lips and stabilising ribs that provide greater contact area and more effective lubrication retention than standard O-ring designs. This results in reduced friction, lower operating temperatures, and significantly extended chain life under demanding conditions.
