About Single-Strand Sprockets

Connect two of these sprockets with a compatible single-strand roller chain to create a chain drive system. Unlike belt drive systems, chain drives will not slip or creep, and they can operate in wet, dirty, or corrosive environments. For use with roller chains that have the same ANSI number.

These ready-to-use sprockets are machined to fit a specific shaft diameter and include a standard keyway and set screws for attaching the sprockets to a shaft.
