  • 18 teeth engage 50 chain smoothly for reliable power transfer

Finished-bore sprocket for 50 chain

The Tritan 50BS18H is a steel sprocket with an 18-tooth profile and a fixed 1 3/16 in bore that includes a 1/4 in wide by 1/8 in deep keyway plus two set screws. It suits maintenance teams and machinery builders who need a direct-drive component for single-strand 5/8 in pitch chain.

Black-oxide finish and compact hub

A black-oxide coating protects the 3.92 in outside diameter and 3.599 in pitch diameter surfaces during normal operation. The one-side hub measures 2 7/8 in across with a 0.657 in projection and a 1 in length through bore, keeping rotational mass low and installation straightforward.

Keyway and set screws lock to shaft

The integrated keyway and dual set screws secure the sprocket to a matching 1 3/16 in shaft without additional clamping hardware. Builders requiring a different bore size, a double-strand hub or a detachable bushing will need a separate component.

Questions about this item

How do I fit the 1 3/16 in bore sprocket onto the shaft and what step is often missed?

Slide the sprocket over the shaft, align the 1/4 in wide by 1/8 in deep keyway with the shaft key, then tighten both included set screws against the key to prevent rotation.

What maintenance or replacement will this 50 chain sprocket need over time?

Inspect the 18 teeth regularly for hooking or uneven wear; replace the sprocket when tooth profiles no longer mesh cleanly with the 5/8 in pitch chain.

What is the first limit reached when this steel sprocket runs continuously under load?

The 3.92 in outside diameter and 1 in length through bore concentrate heat, so tooth-surface temperature becomes the limiting factor before the black-oxide finish degrades.
