Industrial Chain Drive Component

The Tritan 50BS14H is a finished-bore steel sprocket designed for single-strand 50 chain with a 5/8 inch pitch. It suits maintenance teams and OEM builders who need a direct replacement on existing shafting. The 1-1/4 inch bore includes a standard 1/4 by 1/8 inch keyway and two set screws for secure mounting. It arrives new with a black oxide finish.

Sustained Load Behaviour

Hardened steel teeth and a 2.803 inch pitch diameter distribute wear evenly across the 14-tooth profile during continuous operation. The one-sided hub projects 0.657 inch, keeping the chain line stable under steady torque. Black oxide coating resists surface corrosion that accelerates during long duty cycles. Two set screws maintain clamp force without loosening from vibration.

Pre-Order Verification

Confirm the driven shaft measures exactly 1-1/4 inch and carries a matching keyway slot before ordering. Verify the chain in service is ANSI 50 single strand with 5/8 inch pitch. Check that 3.11 inch outside diameter and 2-1/8 inch hub diameter clear adjacent guards or bearings. Ensure the 1 inch length through bore fits the available shaft exposure.

Questions about this item

How much heat does the 14-tooth steel sprocket generate when running all day?

The steel 50 chain sprocket produces minimal heat during continuous operation because it has no internal friction surfaces beyond the chain engagement.

What shaft size and keyway dimensions must I already have for the 1-1/4in bore to fit?

You need a 1-1/4in diameter shaft with a 1/4in wide by 1/8in deep keyway to match the sprocket's fixed bore and included set screws.

Will the 3.11in outside diameter clear the guards on my older 50 chain drive?

The 3.11in outside diameter and 2.803in pitch diameter match standard 50 chain geometry, so it fits existing guards designed for 14-tooth 50 chain sprockets.
