💡 What is a ball bearing used for and why pick the right size for your project?

Choosing the right bearing affects fit, life, and performance.

- Size bore and outer diameter must match shaft and housing for proper clearance and fit.
- Dynamic load rating and speed ratings determine how long it lasts and how fast it runs.
- Lubrication, seals, and operating environment drive maintenance needs and reliability.
