Bearings are.... bearings. A plain bushing is... just a bushing.

The difference? One moves, the other doesn't.

The one with bearings has an inner race that rolls along ball bearings against the outer casing. This results in smoother, longer rotation, with less startup energy required.

A bushing is just a fixed (solid) component.
