Tritan 50BS15H 7/8" Bore Sprocket 15T 50 Chain Collectible

Precision Power Transmission Sprocket

The Tritan 50BS15H is a finished-bore steel sprocket built for 50 chain size with 15 teeth. It features a 7/8 inch bore diameter, a 3.006 inch pitch diameter and a 3.32 inch outside diameter. The hub measures 2 3/8 inches in diameter with a .657 inch projection and a 1 inch length through bore. It includes a 3/16 inch wide by 3/32 inch deep keyway and two set screws for secure shaft locking. The black oxide finish adds corrosion resistance for industrial environments.

Ideal for Single-Strand Chain Drives

This sprocket suits maintenance teams and OEMs replacing worn components on existing single-strand 50 pitch drives where a 7/8 inch shaft is standard. It is not for buyers who need a different bore size, a multi-strand hub configuration or a higher tooth count for altered speed ratios. Applications requiring stainless steel construction or a detachable hub design should look elsewhere.

Ready-to-Mount Hardware Included

The supplied keyway and two set screws eliminate the need to source separate locking hardware, reducing assembly time on the shop floor. The fixed bore and one-sided hub keep the drivetrain compact without additional spacers. Black oxide coating protects the steel during storage and initial operation before lubrication takes over.
