Description
Part #: 197476
Ideal OEM replacement offering 1.5 to 2x longer wear resistance than regular O-ring chains. Each refined component, designed with computer analysis, provides higher tensile strength. Specially controlled heat treatment means tougher material and more durability. Q4 seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and endurance. Q4 seal ring offers less friction, which minimizes power loss, almost half that of standard O-ring chain.
