It would be more helpful to know what kind of motor it's got. Is it one of the blender motor or is it a pancake motor machine?
Believe it or not, some of the pancake motor machines are designed to have the motor hit the trash can when the bearings go. My 7 amp Sanitaire is like this.....the top of the shaft has 2 punch marks to "mushroom" the end of the shaft so the bearing can never be removed. If the bearing goes, in the bin goes the motor...
