💡 What is a sealed ball bearing used for in a DIY automation push-pull actuator, and why does it matter for long-term reliability?

- They enable smooth, low-friction motion in compact motion devices - They seal out dust and moisture to extend service life - They support repeated high-cycle operation with consistent thrust - Ceramic bearings exist for even lower friction in precision setups
