    Flat Sprockets

    Image of Product. Front orientation. Drive Sprockets. Flat Sprockets.
    Save space and cut weight—these sprockets don’t have a raised hub so they’re best for tight spots and lightweight designs. Bolt or weld them to components and mounting surfaces, or add a custom hub. Although they are versatile, they’re harder to align than sprockets with hubs.
    Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.
    Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.
    Plain Bore—Plain bore sprockets give you options—machine a custom bore, weld, or press-fit them in place. They're sized to the minimum shaft diameter listed and are machinable up to the maximum.
