💡 What is a sealed ball bearing commonly used for in compact devices?

In compact gearboxes and hobby machines, a sealed ball bearing provides smooth motion and long life by keeping lubricant in and dust out.

- handy for precision rotation in small motors - protects radial loads in light duty gear trains - reduces maintenance in dusty or hot environments - fits in limited space with simple mounting
