Sprockets for Miniature Roller Chain
Often used in electronic equipment, instrumentation devices, printers, and other compact machinery, these sprockets are made for use with our miniature roller chain.
Acetal sprockets are lightweight, quiet, and nonconductive. Press fit them onto your shaft. Stainless steel sprockets are corrosion resistant for use in harsh environments. Mount them onto your shaft and secure with a set screw.
Sprockets for Harsh Environment Flat-Edge Roller Chain
The teeth on these sprockets are sized to fit Harsh Environment Flat-Edge Roller Chain. To avoid interfering with material conveyed on your chain, the teeth are short and won’t stick out above the chain. For a custom fit on your shaft, machine these sprockets to your exact specifications. They come machined to the shaft diameter listed and are machinable up to the maximum shaft diameter size.

Wear-Resistant Wide-Hub Idler Sprockets for ANSI Roller Chain
Hardened teeth give these steel sprockets increased wear resistance for a long service life. The wide hub provides stability under heavy loads. Designed to rotate freely on built-in bearings, idler sprockets maintain constant tension on your drive by pressing against your chain to take up slack and reduce wear and vibration. They are for use with roller chain tensioners.
