Description
The K15-50B18LKGH SPROCKET (50B18T) is a replacement drive sprocket for LiftMaster gate operators, designed to restore accurate engagement between the drive chain and the operator’s drive system.
In day-to-day use, this sprocket supports reliable gate operation in commercial and industrial installations where consistent chain engagement is essential for predictable opening and closing cycles. It serves as a field replacement when teeth show wear, deformation, or chips, which can lead to chain skip, uneven travel, or increased noise. Installers use this part during routine maintenance or after servicing the drive train to minimize downtime and extend operator life.
Compatible with LiftMaster commercial gate operators that use the 50B18T drive assembly. Confirm compatibility with your model’s drive schematic and replace as part of a matched drive train if multiple components show wear.
