#50-1R OCM OIL PORT SOLID BUSH ROLLER CHAIN FOR LONG LIFE

OCM JAPANESE MANUFACTURED 
COMPETES WITH THE WORLDS BEST ROLLER CHAINS!
10FT OF #50 RIVETED ROLLER CHAIN!
AVERAGE TENSILE STRENGTH:  7160LBS
 
 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
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
