摘要： A split stabilizer bearing for a mast of a rotary distributor includes a split cylindrical housing, a split filament wound bushing, a plurality of polytetrafluoroethylene-coated carbon fiber ring seals, an annular split seal retainer, and multiple fasteners. The filament wound bushing is disposed inside the housing, along an inner surface thereof. The bushing has a backing layer of high-strength glass fiber and an inner sliding layer of polytetrafluoroethylene (PTFE) and polymer fiber, the two layers both embedded in a epoxy resin matrix. The carbon fiber ring seals are disposed on axially or longitudinally opposed sides of the bushing and along an inner side or surface of the cylindrical housing, preferably in respective annular recesses or offsets along the inner side or surface of the housing. The fasteners, nylon-patch locking screws or bolts, couple the bushing and the split seal retainer to the housing.
