Browning 1127661 Finished Bore Sprocket 14T 3/8in Pitch

Product Description

The BROWNING 1127661 is a finished bore roller chain sprocket designed for use with 3/8 inch pitch (ANSI No. 35) roller chain. The bore is factory-machined to a final diameter of 5/8 inch, eliminating the need for secondary machining before installation. With 14 teeth and an outside diameter of 1.84 inches, this sprocket is suited for compact drive configurations where space and weight are limited. Constructed from steel, it delivers the durability required in demanding mechanical drive applications. At 0.32 pounds, it is a lightweight component appropriate for light-duty chain drive assemblies. HVAC technicians, mechanical contractors, and equipment service technicians install this type of sprocket in belt and chain drive systems on fan assemblies, conveyor drives, and auxiliary equipment.

This sprocket is applied in ANSI No. 35 roller chain drive systems commonly found in light commercial and industrial mechanical equipment. Typical installations include fan drives, pump drives, and small conveyor systems where a finished bore sprocket allows direct shaft mounting without additional machining. The 5/8 inch finished bore and 1.25 inch hub diameter suit standard shaft sizes used in fractional horsepower drive trains. It is appropriate for both new installations and replacement of worn or damaged sprockets in existing chain drive assemblies.

Key Features

• Finished bore at 5/8 inch allows direct shaft installation without machining
• Compatible with ANSI No. 35 roller chain at 3/8 inch pitch
• 14-tooth count provides defined speed and torque ratio in drive design
• Steel construction for durability in mechanical drive environments
• Outside diameter of 1.84 inches suits compact drive configurations
• Lightweight at 0.32 pounds for reduced rotational inertia in small drives

Compatibility

Designed for use with ANSI No. 35 roller chain with a 3/8 inch pitch. Suitable as an OEM-style replacement or new-installation sprocket for light-duty chain drive assemblies using a 5/8 inch shaft diameter.

Installation Notes

Installation is typically performed by mechanical contractors or equipment service technicians. De-energize and lock out all power to the drive system before beginning sprocket replacement or installation. Ensure the shaft is clean and free of burrs before sliding the sprocket into position, and verify proper chain alignment and tension after installation per the equipment manufacturer's specifications. Refer to applicable ANSI and OSHA machine guarding requirements for exposed chain drive systems.
