Browning 1128768 Finished Bore Sprocket 14 Teeth 5/8 in

Product Description

The BROWNING 1128768 is a finished bore sprocket designed for roller chain drive applications in industrial and mechanical systems. It features 14 teeth and is machined to accept a 1-1/8 inch bore diameter, making it ready for direct shaft installation without additional machining. The sprocket is sized for 5/8 inch pitch chain, corresponding to ANSI Chain Trade Size 50. With a hub diameter of 2.141 inches and an outside diameter of 3.11 inches, this sprocket fits into compact drive assemblies. Constructed from steel, it provides the strength and wear resistance required for continuous-duty power transmission service. Licensed trades and mechanical contractors install this type of component in conveyor systems, HVAC drives, and general machinery.

This sprocket is suited for roller chain drive systems that use ANSI 50 chain with a 5/8 inch pitch. Typical applications include industrial conveyor drives, blower and fan drive assemblies, pump drives, and other mechanical power transmission setups where a finished bore sprocket with a fixed 1-1/8 inch shaft bore is specified. The steel construction makes it appropriate for both indoor and light-duty outdoor mechanical installations where corrosion is not a primary concern.

Key Features

• Finished bore machined to 1-1/8 inches — ready for direct shaft mounting
• 14-tooth profile for ANSI 50 roller chain with 5/8 inch pitch
• Outside diameter of 3.11 inches fits compact drive envelope designs
• Hub diameter of 2.141 inches provides adequate material for keyway and setscrew retention
• Steel construction delivers durability in continuous-duty power transmission service

Compatibility

Designed for use with ANSI Chain Trade Size 50 roller chain at 5/8 inch pitch. The bore is fixed at 1-1/8 inches minimum and maximum, so shaft diameter must match exactly.

Installation Notes

Installation should be performed by a qualified mechanical technician or millwright. De-energize and lock out the drive system completely before removing or installing any sprocket. Align the sprocket carefully with its mating sprocket and chain to avoid premature wear on the chain and tooth faces. Verify setscrew and keyway engagement per standard mechanical drive practices before returning the system to service.
