Tritan 50BS15H Sprocket 15T

This Tritan sprocket is a finished-bore power-transmission component designed for single-strand roller chain drives. It suits maintenance engineers and machinery builders replacing worn drive parts on conveyors, agricultural equipment or light industrial drives.

Check chain pitch and shaft dimensions

Verify that the existing drive uses 5/8 in pitch chain designated as number 50 and that the driven shaft measures exactly 1 1/4 in diameter. Confirm the keyway slot on the shaft matches the 1/4 in width and 1/8 in depth cut into this hub.

Hub fits standard 50 chain drives

The 2 3/8 in hub diameter and 0.657 in projection seat against a bearing or spacer, while the 1 in length through bore provides full shaft engagement. Two included set screws lock the sprocket axially, freeing the key from shear load and simplifying alignment on the drive line.

Questions about this item

Does the Tritan 50BS15H sprocket ship with the two set screws and keyway already machined, or must I source those separately?

The sprocket includes two set screws and a finished bore with a 1/4 in wide by 1/8 in deep keyway machined at the factory, so no separate hardware is needed for installation.

How do I decide between the 15-tooth 50 chain sprocket and other tooth counts for my 5/8 in pitch drive?

Choose the 15-tooth version when the design calls for a 3.006 in pitch diameter and 3.32 in outside diameter; other tooth counts change those diameters and the resulting speed ratio.

What does the 3.32 in outside diameter mean once the sprocket is mounted on a 1-1/4 in shaft?

It sets the maximum radial envelope to 3.32 in, clearing 2 3/8 in hub projection of 0.657 in, so guards and adjacent components must allow that space.
