A microfilm cartridge assembly comprising:

• a housing including from and rear walls maintained in generally parallel spaced relation, and further including a centrally located polymeric post extending generally perpendicular inwardly into an interior portion of said housing from said rear wall, said post having a predetermined maximum height, said post further having an upper engagement surface;
• and
• a reel having a hub centered about an axis of rotation of said reel, said hub including a metallic bottom wall, said hub having a depth which is slightly less than the height of said post, said reel being received within said housing with said hub received on said post for suspended rotation thereon, said upper engagement surface of said post engaging with the metallic bottom wall of said hub.

A microfilm cartridge assembly comprising:

• a housing including front and rear walls maintained in generally parallel spaced relation, and further including a centrally located polymeric post extending generally perpendicular inwardly into an interior portion of said housing from said rear wall, said post having a predetermined maximum height, said post further having an upper engagement surface;
• and
• a reel comprising an outer hub centered about an axis of rotation of said reel, and front and rear cylindrical flanges extending radially outwardly from the outer hub for capturing the edges of a film wound onto the outer hub, said reel further comprising an inner hub formed concentrically within the outer hub and disposed adjacent to the rear flange of the reel, said reel still further comprising a metallic insert which is received and secured within said outer hub between the front and rear flanges of the reel, said insert being received adjacent an inner side of the inner hub whereby said insert forms a bottom wall of said inner hub, said inner hub having a depth which is slightly less than the height of said post, said reel being received within said housing with said inner hub received on said post for suspended rotation thereon, said upper engagement surface of said post engaging with the metallic insert which forms the bottom wall of said hub.
