Boston Gear spur gears are designed to transmit motion and power between parallel shafts. The different styles offered include spur, gear rack, pinion wire, stem pinions, and internal gears, and most come with a selection of bore diameters, keyways, and setscrews to accommodate a wide variety of application requirements. They are available in plastic, non-metallic, brass, steel, and cast iron and are manufactured in a variety of styles, including plain, web, web with lightening holes, and web with spokes. Many are available with or without hubs. Boston Gear manufactures both 14 1/2° and 20° PA, involute, full-depth system gears. While 20° PA is generally recognized as having a higher load-carrying capacity, 14 1/2° PA gears are used extensively because of lower backlash and smoother, quieter operation. Just ask your CSR which is best for you. And remember that spur gears and rack are available via our Guaranteed Same Day Shipment Program.Product FamilySpur GearsDiametrical Pitch6Product DescriptionSpur Gear, 6 DP, 14 1/2 PA, 120 Teeth, Cast IronAltra Master No.30216089Pressure Angle14-1/2 Degree Pressure AngleMaterialCast IronBore Size1.250UPC781711104484Face Width1.500Family Id30,088Weight38.901KeywayNo KWY or SetscrewPitch Diameter20.000Outside Diameter20.330Unit Of MeasureEnglishNo Of Teeth120Hub Diameter3.500Setscrew OtherNo SetscrewTorque Rating5987 @ 100 RPM MAX
