r super performance aximum quality building better bushings the attention to detail in tsubaki ansi chains is astounding consider the care that goes into the strong long-lasting curled bushings we start with specially selected steels for maximum wear life and strength we add lube grooves which help hold oil at the point of contact where chain needs it most during operation then we heat-treat for added durability and wear life longer wear life tsubaki ansi chain pre-lubricated chain elongation former tsubaki chain pre-lubricated lubric 30 ated driving hours dimensional control which bushing do you want turning in your operation other manufacturers stamped or forged bushings that other manufacturers use can have many forms unfortunately cylindrical isn t usually one of them as a result poor pin-bushing interaction may cause premature wear tsubaki curled bushings from tsubaki are precisely formed round cylinders this carefully engineered process results in better surface contact between pin and bushing that means reduced initial elongation and improved wear life 2
