Does such a motor have bearings?

Can you see from the picture/description whether it has a start cap?

Every motor has bearings. Some are sleeve type, others are ball or roller
type. Over time the bearing wear out, lubrication dries up and the motor
has more frictional resistance to overcome. Larger motors can be rebuilt,
but most smaller ones are throw-aways.

Some motors can be lubricated and will last for many years running 24/7,
others are sealed and required no lubrication.
