Industrial Chain Sprocket

The Tritan 40BS32H is a finished-bore steel sprocket designed for 40 chain size and single-strand drives. It suits maintenance teams and OEM builders who need a direct-fit replacement on existing shafts with a 3/4 in bore and standard keyway.

Capacity and Headroom

With 32 teeth, a 5.38 in outside diameter and 5.101 in pitch diameter, it transmits torque smoothly on #40 roller chain at moderate speeds. The 1 in length through bore and 3/4 in maximum bore limit use to shafts of that exact size; larger shafts or multi-strand chains require a different sprocket.

Black Oxide Finish and Hardware

The black oxide coating adds corrosion resistance for indoor and light outdoor environments. Two set screws and a 3/16 in wide by 3/32 in deep keyway are included, securing the hub against rotation without extra machining or separate fastener kits.

Questions about this item

Will the 3/4in bore and 3/16in keyway width match the shaft on my existing #40 chain drive?

The sprocket has a fixed 3/4in bore with a 3/16in wide by 3/32in deep keyway and two set screws, so it fits a standard 3/4in keyed shaft for #40 chain.

How can I confirm the 32-tooth sprocket is seated correctly after installation?

Check that the 5.38in outside diameter runs true, the 1in length through bore sits flush on the hub, and both set screws lock onto the key without wobble.

Does the box include the two set screws or must I source them separately?

The finished-bore sprocket ships with both set screws included; no additional hardware is required for mounting.
