 Re-Punched Link Holes
OCM's repunching process removes the taper
of hole. Both sides of the hole are parallel, better
bearing between pins and holes. 
This process increases fatigue strength
Shot-Peening

Rollers and link plates are shot peened to increase fatigue strength

Cylindrical Roundness - Solid Bushings
The advantage of solid bush, cylindrical roundness, makes for a large bearing area and oil port as an oil reservoir, improves the chain wear resistance and minimize chain elongation.
Preloading
OCM roller chain is preloaded automatically after 
assembly to minimize initial elongation
