💡 What does a roller chain sprocket do in industrial setups? These parts keep chains moving smoothly on shafts in drive systems. - They mesh with chain links to transfer power without slip in machines - Fixed mounting on a shaft lets them handle speeds common to drive sprockets - At least three teeth stay in contact for stable chain grip over time - Common in milling rigs and other mechanical transmission spots
