OCM JAPANESE MANUFACTURED
COMPETES WITH THE WORLDS BEST ROLLER CHAINS!
10FT OF #80 RIVETED ROLLER CHAIN!
AVERAGE TENSILE STRENGTH: 17630LBS
Oil Port oriented + Solid Bush
These holes, located on the inner side of the bushings away from bearing area, function as a reservoir for extra lubricant. This feature reduces chain wear and extend the chain’s operating life.
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
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.
OCM roller chain is preloaded automatically after
assembly to minimize initial elongation
