💡 What is a chain sprocket used for in power transmission?

This handy component translates rotary motion into chain-driven motion, delivering torque along straight paths.

- Transmits torque from a drive shaft to a chain for straight-line motion - Maintains a fixed gear ratio and minimizes slip in conveyors and machines - Requires correct matching of pitch, bore, teeth count, and hub design
