Self-lubricated bearings

Polygon Co. announces its line of PolyLube custom-engineered and standard composite plain bearings, which are designed for use in wheel loaders, excavators, backhoes, and compact track loaders. Featuring high load-bearing capacity, low frictional values, and corrosion resistance, the composite bearings are self-lubricated, requiring no grease and reducing maintenance labor costs. The bearings are made of continuous filament-wound glass fibers, polymer resins, and polytetrafluoroethylene fabric liners. The fiberglass filament and epoxy resin combine to form a high-strength backing. This filament-wound fiberglass structure allows for thin-walled, lightweight bearings.
