Industrial Roller Chain Sprocket

The Tritan 80SF21H is a hardened-steel sprocket built for ANSI 80 roller chain. It suits maintenance crews and OEM builders who need a direct replacement on conveyors, drives or agricultural equipment. The black-oxide finish resists corrosion in harsh shop environments.

21-Tooth Pitch Diameter Match

The critical spec is the 6.71 in pitch diameter paired with a 1 in chain pitch. This combination determines whether the sprocket meshes correctly with your existing 80-series chain and maintains proper speed ratio. Verify the pitch diameter against your drive layout before ordering.

Quick-Detachable Bushing Fit

Designed for an SF quick-detachable bushing, the sprocket mounts without set-screws and allows fast removal for chain service. The 2 15/16 in maximum bore covers a wide shaft range. Hardened teeth extend wear life, reducing downtime on high-cycle applications.

Questions about this item

How does the 21-tooth count affect the speed ratio on my machine?

With 21 teeth and a 6.71 in pitch diameter, this sprocket drives ANSI 80 chain at a fixed ratio determined by the mating sprocket size.

What does the ANSI B 29.1 standard guarantee for chain engagement?

It defines the 1 in pitch, 0.575 in tooth width and hardened-tooth profile so any compliant ANSI 80 single-strand chain meshes correctly.

What bore and hub dimensions must my shaft and space accommodate?

The SF quick-detachable bushing accepts up to 2 15/16 in bore; the hub is 5 in diameter, projects 1.675 in and has a 2 1/4 in length through bore.
