Browning 1642719 Finished Bore Sprocket 11T 3/8 Pitch

Product Description

The BROWNING 1642719 is a finished bore sprocket designed for use with ANSI No. 35 roller chain. It features 11 teeth and a 3/8-inch chain pitch, with a fixed 1/2-inch bore diameter ready for direct shaft installation without additional machining. The outside diameter measures 1.5 inches and the hub diameter is 1.06 inches. Constructed from steel, this sprocket is suited for light-duty drive applications where a compact, pre-bored component is required. Licensed HVAC and mechanical technicians, as well as industrial maintenance professionals, commonly install this type of sprocket in low-speed chain drive assemblies.

This sprocket is appropriate for residential and light commercial mechanical drive systems using ANSI No. 35 roller chain. Typical applications include small conveyor drives, fan drives, and auxiliary equipment drives where an 11-tooth steel sprocket with a 1/2-inch bore fits the shaft and chain specification. The finished bore eliminates field machining, making it a direct drop-in component for properly sized shafts.

Key Features

• 3/8-inch chain pitch matches standard No. 35 chain trade size
• Fixed 1/2-inch bore diameter — no machining required
• 1.5-inch outside diameter for compact drive configurations
• Steel construction for durability in mechanical drive service
• Lightweight at 0.26 pounds — suitable for small-shaft applications

Compatibility

Designed as an OEM-style replacement or new-installation sprocket for mechanical drive assemblies using ANSI No. 35 roller chain with a 3/8-inch pitch and a 1/2-inch drive shaft.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with chain drive systems. Shut down and lock out all power to the drive system before removing or installing sprockets. Ensure the shaft diameter matches the 1/2-inch finished bore exactly before pressing or securing the sprocket. Verify chain alignment and tension after installation per the equipment manufacturer's guidelines.
