Composite spherical and journal bearings are for use in hostile environments, particularly where corrosion resistance is important. These bearings feature a spherical outer surface and are constructed of Teflon and polyester fibers woven into a self-lubricating, bondable fabric supported by a filament-wound, fiberglass epoxy shell. The bearings are self-aligning and can take dynamic misalignment, oscillating, and linear motion. The bearings are targeted for use in surgical and optical equipment, especially where corrosive fluids such as blood and saline solution are present.
