Browning 1117779 Finished Bore Sprocket 11T 1/2in Pitch

Product Description

The BROWNING 1117779 is a finished bore roller chain sprocket designed for use with 41-series roller chain at a 1/2 inch pitch. Manufactured from steel, this sprocket features 11 teeth and a fixed 5/8 inch bore diameter, meaning no secondary machining is required before installation. The outside diameter measures 2 inches. It is a compact, single-strand sprocket suited for light-to-medium duty power transmission applications in conveyor systems, agricultural equipment, and general industrial machinery. Installation is typically performed by mechanical technicians and maintenance professionals working on chain-driven drive systems.

This sprocket is sized for applications requiring a low tooth count at 41-chain pitch, making it well suited for drive configurations that need a small driver or driven sprocket in a compact shaft arrangement. The finished bore construction allows direct mounting onto a 5/8 inch shaft, reducing setup time in production or field-service environments. Typical uses include small conveyor drives, packaging equipment, and light industrial drive trains where 41-series roller chain is already specified.

Key Features

• Finished bore at 5/8 inch — mounts directly to shaft with no additional boring required
• 41-series chain compatibility at 1/2 inch pitch
• 11-tooth count for compact, low-ratio drive configurations
• Steel construction for durability in industrial drive environments
• 2 inch outside diameter for space-constrained installations

Compatibility

Designed for use with ANSI 41-series roller chain at 1/2 inch pitch. Compatible with any 5/8 inch diameter shaft where a finished bore sprocket is appropriate. No additional compatible model numbers were specified in the product data.

Installation Notes

Installation is typically performed by a qualified mechanical technician or millwright. Before mounting, shut down and lock out the drive system per OSHA lockout/tagout procedures. Align the sprocket carefully with mating components to avoid premature chain and sprocket wear. Secure with an appropriately sized key and setscrew or retaining hardware as required by the shaft configuration.
