💡 What makes one-way clutches essential in industrial design?

1. They ensure components rotate in only one direction to prevent backflow or system reversal.

2. Common in conveyor systems, they stop gravity-driven rollback during power outages.

3. Used in hydraulic and printing systems for indexing, where precise step-by-step motion is needed.

Designed for reliability in demanding systems requiring controlled, one-way motion.
