IntroductionBlackstar SprocketsBlackstar sprockets are made with superior materials:SAE 1045 SteelBlackStar uses SAE 1045 steel, which is more wear-resistant than our competitors’ 1020 and 1018 steel orpowdered metal. SAE 1045 steel is also able to be hardened, unlike some other types of steel.Black Oxide TreatmentBlack Oxiding on roller chain sprockets provides rust-resistance and provides an attractive finish.Hardened TeethBlackStar offers induction-hardened teeth from the factory.Forged ConstructionBlackStar offers many sizes in a one-piece forged construction, which provides superior strength and grainstructure.Fully Machined Mill SprocketsBlackStar’s fully machined mill sprockets are precise. Our competitors’ mill sprockets are flame cut withvery loose tolerances on the tooth profile and from the root to the center of the bore. BlackStar machinebevels and induction hardens all mill sprocket teeth for smoother running and longer life.BlackStar makes its mill sprockets from SAE 1045 steel.Custom SprocketsBlackStar manufactures sprockets custom-made to yourspecifications.All dimensions in inches.www.BlackStarPT.com 1
