Browning 1127653 Finished Bore Sprocket 13T 3/8in Pitch

Product Description

The BROWNING 1127653 is a finished bore roller chain sprocket designed for use with ANSI No. 35 chain. It features 13 teeth, a 3/8 inch chain pitch, and a 3/4 inch finished bore diameter. The hub diameter measures 1.39062 inches and the outside diameter is 1.75 inches. Constructed from steel, this sprocket is built for reliable power transmission in light-to-medium duty mechanical drive applications. It is installed by mechanical technicians and maintenance professionals working on conveyor systems, drive assemblies, and related chain-driven equipment.

This sprocket is suited for ANSI No. 35 roller chain drive applications in both industrial and commercial settings. Typical installations include conveyor drives, small machinery, and general power transmission assemblies where a finished bore sprocket with a fixed 3/4 inch bore is the correct fit. The finished bore eliminates the need for secondary boring or machining before installation, making it ready to mount directly to a 3/4 inch shaft.

Key Features

• Finished bore design at 3/4 inch — ready to install on matching shaft without additional machining
• 13-tooth count delivers the required speed ratio and chain wrap for light-to-medium drive loads
• 3/8 inch pitch matches ANSI No. 35 roller chain standard
• Steel construction provides durability in mechanical drive environments
• 1.75 inch outside diameter and 1.39062 inch hub diameter for compact drive configurations
• Lightweight at 0.26 pounds, suitable for smaller drive assemblies

Compatibility

Designed for use with ANSI No. 35 roller chain (3/8 inch pitch). Fits 3/4 inch shafts. Suitable as an OEM-style or replacement sprocket in any No. 35 chain drive assembly requiring a 13-tooth finished bore sprocket.

Installation Notes

Installation is typically performed by qualified mechanical or maintenance technicians. De-energize and lock out all power to the drive system before removing or installing any sprocket. Ensure shaft diameter matches the finished bore exactly before mounting, and secure with the appropriate keyway and set screw arrangement per the driven equipment manufacturer specifications. Verify chain alignment and tension after installation to prevent premature wear.
