#80-2R OCM Japanese Double Strand Roller Chain 10ft Roll with Connecting Link

OCM JAPANESE MANUFACTURED  COMPETES WITH THE WORLDS BEST ROLLER CHAINS! 10FT OF #80-2R RIVETED DOUBLE STRAND ROLLER CHAIN! AVERAGE TENSILE STRENGTH:  35,280LBS    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. WIT
