A mounting collar is for supporting a vacuum cleaner filter bag in a mounted condition over a vacuum cleaner fill tube. The fill tube has a cylindrical outer surface. A panel of the mounting collar is configured to be attached to the filter bag. The panel has a first inner edge defining a first opening for receiving the fill tube. An elastomeric diaphragm of the collar extends across the first opening. The diaphragm has a second inner edge defining a second opening. The second inner edge is configured to be elastically stretched circumferentially about the fill tube and to be in contact with the cylindrical outer surface about the entire circumference of the cylindrical outer surface when the first opening receives the fill tube. A lobe of the diaphragm is defined by the second inner edge and a baseline. The baseline extends from a first point on the second inner edge to a second point on the second inner edge and is located entirely on the diaphragm.

An apparatus includes first and second wheel sections configured to mate in axially opposed relationship to define a rotatable wheel body. The wheel body has a peripheral outer surface extending circumferentially about an axis of rotation and a bearing cavity centered on the axis. Each of the wheel sections has an axial projection and an axial recess configured to receive the projection on the other of the wheel sections. This limits rotation of the wheel sections relative to each other about the axis when the wheel sections are received in the axially opposed relationship.
