    Pair with flat-belt pulleys for low-speed pulling and to counterbalance machine tools, elevator and oven doors, and forklift masts. Made of interlaced plates held together by rivet pins, leaf chain has a higher tensile strength than roller chain. Also known as counterbalance chain.
    When servicing worn leaf chain, replace the entire chain—do not splice chain together or mix old and new chain.
    Clevis-Connecting Link—Attach the end of your chain to an anchor point or load with a clevis.

    Add these links to your roller chain to attach brackets and guides, move items directly, or trip switches in conveying, timing, and aligning setups. Like the chain on a bike, the side plates have a figure-eight shape that grips sprockets to transmit power between rotating shafts without slipping. We offer compatible chain for your convenience. When using your own chain, make sure the trade numbers match. Do not use these links with our Low-Maintenance Roller Chain.
    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.
    Pin—The pins are extended to trip switches.
