💡 What’s a one-way bearing used for?
It locks in one direction and spins freely in the other. Here's where they shine:

1. Indexing or step-feed machinery

2. Backstop to prevent reverse rotation

3. Overrunning applications like alternators

If you want to keep things turning one way and lock out the rest - this one’s your guy. Let it do the holding while you keep on rolling!
