A compressor comprising:
- a shell;
- a compression mechanism disposed within said shell;
- a drive shaft drivingly engaged with the compression mechanism;
- a bearing housing engaged with said compression mechanism;
- a hub disposed within said shell and defining an axis of rotation, said hub including an axially extending aperture, said drive shaft engaged with said axially extending aperture;
- a motor assembly driving said drive shaft about said axis of rotation;
- a bearing insert disposed within said aperture and rotatably supporting said drive shaft;
- and
- at least one collar disposed about said hub,
- wherein said at least one collar is mounted on said hub to create an interference fit between the at least one collar and the hub and retain the at least one collar on the hub.
