A bearing assembly for supporting a drive shaft, having a housing with a central bore in which is mounted a shell with a polygonal shaped opening, a plurality of circumferential spaced staves are mounted in the polygonal opening presenting a plurality of flat planar surface that tengentially contact a drive shaft. The staves have a outer layer made of high molecular weight and an inner layer made of an elastomeric material. The staves are retained within the polygonal opening with the retainer rings. A method for manufacturing such a bearing assembly is disclosed, the method comprising placing a plurality of laminated, trapezoidal shaped staves about a polygonal shaped mandrel; wrapping a fiber fabric about the outer periphery and curing a resin coating placed thereon; and securing a pair of annular retainer rings thereabout to secure the staves to the cured shell.
