A screw assembly comprising:
- a screw housing comprising a first wall;
- a screw situated in and cantilevered to said first wall;
- and
- a bearing assembly secured to said first wall of said screw housing and adapted to facilitate rotation of said screw relative to said first wall, said bearing assembly comprising a bearing housing that houses at least one solid oil bearing comprising oil in a polymer structure that is adapted to retain or reabsorb said oil;
- wherein said first wall and at least a portion of said bearing housing are formed of a single casting.

A screw assembly comprising:
- a multiple wall assembly comprising a first and second wall that are adjacent to each other and spaced apart;
- a screw cantilevered to at least said first wall of said multiple wall assembly;
- and
- a bearing assembly secured to said first wall of said multiple wall assembly, said bearing assembly adapted to facilitate rotation of said screw relative to said first wall, said bearing assembly comprising a bearing housing that houses at least one solid oil bearing comprising oil in a polymer structure that is adapted to retain or reabsorb said oil;
- wherein said first wall and at least a portion of said bearing housing are formed of a single casting.
