    Sprockets

    Plain Bore

    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.

    Pair this chain with sprockets to transmit power between rotating shafts. Like the chain on a bike, the side plates have a figure-eight shape that grips the sprockets without slipping.
    Lubrication is key to smooth operation and long chain life. Routinely apply oil by hand or install an oil dispenser for continuous lubrication.
    Steel—The go-to for roller chain, steel is strong and economical. While proper lubrication helps prevent rusting, it’s not as corrosion resistant as coated or stainless steel.
    Connecting Link—Use a single link to join both ends of your chain. Start by removing the spring clip or cotter pin from the link’s side plate. Then, slide the link pins into the mating rollers at each end of your chain and snap the clip back on. Also known as master links.
    Adding-and-Connecting Link—An all-in-one link for adding and connecting. It adds a half-pitch length at the roller end, allowing finer length adjustments than full-pitch links. The pin end connects to your chain—except for trade number 25, which requires a separate connecting link. Remove the side plate to install. Also known as half links and offset links.
