Precision Power Transmission Sprocket

The Tritan 50BS17H is a finished-bore roller chain sprocket built for single-strand 5/8 in pitch chain. It suits maintenance engineers and machinery builders who need a direct-fit replacement on existing shafts. The steel body carries a black oxide finish and a 1 1/2 in bore with a 3/8 in keyway for positive torque transfer.

Verify Shaft and Chain Compatibility

Confirm the driven shaft measures exactly 1 1/2 in and provides a standard keyseat matching the 3/8 in keyway width. Ensure the chain in service is ANSI 50 single strand with 5/8 in pitch; the sprocket has 17 teeth, a 3.401 in pitch diameter and a 3.72 in outside diameter. The hub projects .657 in from the bore face and measures 2 11/16 in across.

Hardware Included for Immediate Installation

Two set screws ship in the box, allowing the hub to be locked onto the keyed shaft without sourcing separate fasteners. The fixed-bore design removes the need for a separate bushing or adapter, reducing parts count and assembly time on the production line or in the field.

Questions about this item

Does the sprocket ship with the two set screws already in the hub, or do I need to buy them separately?

The finished-bore sprocket includes two set screws in the hub, so no separate hardware purchase is required.

Should I choose this 17-tooth model or a different tooth count for my 5/8-inch pitch chain?

Select the 17-tooth version when your drive ratio calls for a 3.401-inch pitch diameter; otherwise match the tooth count to the speed and torque requirements of your specific chain drive.

What does the 3.72-inch outside diameter mean when the sprocket is mounted on a 1 1/2-inch shaft?

The 3.72-inch outside diameter is the overall width of the 17-tooth steel sprocket once it is secured on the 1 1/2-inch bore with the 3/8-inch keyway and set screws.
