Sprocket for 40 Chain with 13 Teeth

This TRITAN sprocket is a finished-bore power-transmission component designed for single-strand 40 chain with a half-inch pitch. It has 13 teeth, a 1-inch bore with a keyway, and a black-oxide steel finish. Two set screws are included for secure shaft mounting.

Fits 1-in shafts needing a keyway

The 1-inch bore with a quarter-inch wide by one-eighth-inch deep keyway suits shafts that require positive drive location. Builders using a different bore size, a different chain pitch, or a multi-strand chain will need a different sprocket.

Handles single-strand 40 chain loads

With a 2.33-inch outside diameter and 2.089-inch pitch diameter, the sprocket provides standard engagement for 40 chain. The hub projects 0.591 inches and measures 1 9/16 inches across, limiting use where a longer through-bore or larger hub is required.

Questions about this item

What chain pitch and size does the 13-tooth sprocket require?

The sprocket is made for 1/2 in pitch chain, designated as chain number 40, and fits a single-strand roller chain.

Will the 1 in bore with 1/4 in keyway and 1/8 in depth match my existing shaft and key stock?

The fixed bore measures 1 in, the keyway is 1/4 in wide and 1/8 in deep, and two set screws are included for locking to the shaft.

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

Measure the outside diameter at 2.33 in, verify the hub projection is 0.591 in, and check that both set screws engage the keyway and shaft securely.
