A bushing is a bearing.

Pasted:
Bushings, also called sleeve bearings, are just one specific type of bearings. They are made to slide over rods to provide an extremely low-friction motion. They are excellent for shock absorption and work to minimize energy usage, noise, and wear. Bushings are widely used for heavy-duty wheels that require high load-bearing tolerances.
And:
A bushing is a thin tube or sleeve that allows relative motion by sliding (our type), as compared to rolling. ... Thus, a bushing is a bearing, but a bearing is not necessarily a bushing type. A bearing is the general term for something that allows relative motion between two components, surfaces, etc.
