Ideal O.E. replacement Q4 Sealed Chain (Q4 seal-ring chain) offers 1.5 to 2 times 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, more durability
Q4 seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and fatigue strength
Q4 seal ring offers less friction, which leads to less power loss -- almost half of that of standard O-ring chain
Round rivet head offers superior rigidity over 2 or 4-point (quad-staked) riveting
This new Premium fits a wider range of machine applications.
