LiftMaster #50 Chain 16-Tooth Sprocket – 1" Bore with 1/4" Keyway
Replace a worn, damaged, or slipping drive sprocket with this 16-tooth sprocket designed for compatible LiftMaster commercial garage door operators. It is made for use with #50 roller chain and features a 1-inch center bore with a 1/4-inch keyway.
This sprocket transfers rotational power from the operator shaft to the drive chain. Worn or damaged sprocket teeth can cause chain skipping, excessive noise, uneven door movement, and premature chain wear.

How It Works
The sprocket mounts onto the operator shaft and engages the #50 roller chain. As the operator motor turns the shaft, the sprocket moves the chain and transfers power through the commercial door operator’s drive system.
Compatibility
Designed for compatible LiftMaster commercial garage door operators that require a 16-tooth #50 chain sprocket with a 1-inch bore and 1/4-inch keyway.
Commercial operators may use sprockets with different tooth counts, bore diameters, keyway sizes, hub configurations, and chain sizes. Verify all measurements and compare the original sprocket before ordering.

Installation Requirements
Disconnect electrical power to the commercial operator before beginning service. Inspect the roller chain, shaft, key, bearings, and related drive components for wear or damage before installing the replacement sprocket.
Confirm that the sprocket is properly aligned with the chain and secured to the shaft. Incorrect alignment can cause noise, chain wear, skipping, or damage to the operator.
Installation & Safety
Commercial garage door operators contain moving chains, heavy mechanical components, and electrical connections. Installation and repairs should be completed by a qualified commercial garage door technician.
