When your chain drive system starts acting up—slipping, skipping, or making noise—it’s often the sprocket that’s worn down from years of field work. This 19-tooth 40 chain sprocket gets your equipment back in sync and running smooth. Whether it’s on a conveyor, drive system, or any machinery that relies on precise chain engagement, a fresh sprocket makes all the difference.

What You’re Getting

  • Precision-machined 19 teeth designed for perfect 40 chain engagement
  • W-series hub construction that handles the torque and stress of agricultural work
  • Welded construction that stays put under heavy loads and vibration
  • Direct replacement design that fits your existing setup without modifications

Built for Real Farm Work

This sprocket is designed for the kind of equipment that keeps your operation moving—from grain handling systems to feed mixers, conveyors to drive mechanisms. The 40 chain size is one of the most common in agricultural applications, found on everything from smaller utility equipment to mid-sized farm machinery that needs reliable power transfer.

Made to Last

Farm equipment doesn’t get babied, and this sprocket is built for that reality. The welded hub construction means the teeth won’t separate from the hub under load, while the steel construction handles the daily grind of dust, moisture, and temperature swings that come with outdoor work.

Good to Know

Installation is straightforward—just remove the old sprocket and slide this one on. Make sure your chain tension is properly adjusted after installation, as a worn sprocket often means your chain has stretched some too. Keep a little chain lube handy while you’re at it—fresh sprockets and well-lubricated chains are a team that’ll serve you well.
