Description
The All-O-Matic 50B20TX78 Gearbox Small Drive Sprocket is a replacement drive component used inside compatible All-O-Matic gate operator gearboxes. This sprocket engages the drive chain and helps transfer motor torque through the gearbox, supporting smooth and consistent gate movement.
Over time, drive sprockets can wear, chip, or lose proper tooth engagement due to heavy use, chain tension issues, or normal operator cycling. Replacing a worn sprocket helps restore proper chain tracking, reduce slipping, and prevent inconsistent gate travel, slowdown, or stalling.
Sold by GatePoint Solutions, this replacement sprocket is intended for All-O-Matic operators that use the 50B20TX78 gearbox configuration. It is a practical maintenance part for service technicians repairing commercial, residential, or high-cycle automated gate systems.
