GGB Plain Bearing

From humble beginnings over 120 years ago to a leader in product development, GGB continues advancing surface engineered solutions through innovation and expertise.Metal-polymer plain bearings consist of a metal backing, usually steel or bronze, onto which is sintered a porous bronze layer that is then impregnated with PTFE and additives to obtain a running surface that offers anti-friction and wear resistant bearing properties. These bearings can operate dry or with external lubrication.Plain bearings also may be made of engineered plastics, which provide excellent wear resistance and low friction in both dry and lubricated operating conditions. Being injection molded, they can be designed to almost any shape and produced from a variety of resins compounded with reinforcing fibers and solid lubricant. These bearings exhibit excellent dimensional stability, low coefficients of friction and good thermal conductivity. Fiber reinforced composite bearings are another form of plain bearing that consists of a filament-wound, fiberglass-impregnated, epoxy backing with a variety of low-friction, wear-resistant bearing linings. This structure enables the bearings to support high static and dynamic loads, while their inert nature makes them suitable for corrosive environments.Monometallic, bimetallic and sintered bronze plain bearings are designed for use in both land-based and submerged industrial applications under high load with slow speed movements. Solid bronze bearings impregnated with lubricant provide maintenance-free performance in high temperature applications, whereas monometallic and bimetallic bearings are designed for lubricated application
