Browning 1128602 Finished Bore Sprocket 11T 5/8 in Pitch

Product Description

The BROWNING 1128602 is a finished bore roller chain sprocket designed for power transmission applications in industrial and mechanical drive systems. Machined from steel, this sprocket features 11 teeth and accepts a 5/8 inch pitch chain (Chain Trade Size 50). The bore is fixed at 7/8 inch, meaning no additional machining is required before installation. The finished bore design makes this a ready-to-install component for technicians assembling or replacing drive train components in conveyors, pumps, and general machinery. Outside diameter measures 2.5 inches.

This sprocket suits light-to-medium duty roller chain drive assemblies using No. 50 chain. It is appropriate for use in industrial equipment, agricultural machinery, material handling systems, and mechanical power transmission setups where a finished bore is specified. The fixed 7/8 inch bore suits standard shaft sizes common in these applications. Maintenance technicians and millwrights typically encounter this type of sprocket during scheduled drive system rebuilds or component replacement.

Installation Notes

Installation is typically performed by a millwright or qualified mechanical technician. Disconnect and lock out all power to the drive system before removing or installing sprocket components. Ensure the shaft diameter matches the 7/8 inch finished bore before attempting to mount the sprocket. Align the sprocket carefully with mating components and verify chain tension after installation per the equipment manufacturer's specifications.
