LiftMaster lists this sprocket among the component options for compatible MAXUM JDC and JHDC commercial operators. The correct sprocket depends on the operator, door type, drum configuration, and required operating speed.
Confirm the complete part specification before ordering. This 1" bore version differs from the similar 1-1/4" bore model. Tooth count also affects the drive ratio and should not be changed without consulting the applicable LiftMaster documentation.
Have a qualified commercial door technician install the sprocket with operator power disconnected and locked out. Inspect the chain and mating sprocket, confirm alignment, adjust chain tension, and complete all required operational tests.
Order this 22-tooth sprocket when the approved configuration requires #50 chain, a 1" bore, and a 1/4" keyway.
