Boston Gear 29947 65 RIV PKG 65 RIVETED CHAIN

Boston Gear change gears are used primarily on machine tools to provide different cutting speeds while using a constant speed input. All Boston Gear change gears are manufactured with a double key to accept the compound steel bushings that connect two gears together, allowing them to spin on an intermediate shaft. The change gears we stock range from 20-tooth through 128-tooth gears, in one tooth increments, depending upon the diametrical pitch, for a nearly infinite number of ratio possibilities. Be sure to ask for the Boston Gear compound steel bushings designed specifically for use with these gears.Product FamilyChange GearsDiametrical Pitch20Product DescriptionChange Gear, 20 DP, 14 1/2 PA, 65 Teeth, Cast IronAltra Master No.30216273MaterialCast IronBore Size0.625UPC781711108307Face Width0.375Family Id30,062Weight0.721KWY/Setscrew/OtherW/ Double KWY OnlyPitch Diameter3.250Outside Diameter3.350No Of Teeth65Hub Diameter1.560Torque Rating58.0 @ 900 RPM MAXUnit Of MeasureEnglish
