Abstract
Adjustable gap hydrostatic bearings and adjustable gap seals wherein the adjustable gaps are useful to compensate for wear, thermal expansion, journal speed, and radial deflection of the journal. A housing 10 is adjacent to a journal 2. The housing contains an annular electrodeformable material 5 which will expand or contract radially with the application of voltage and thus adjust the gap between the liner material 3 and the journal.
