GGB offers a broad range of sizes, forms and materials in monometallic and bimetallic bearings. Bimetal and metal bearings offer excellent corrosion resistance in industrial outdoor applications and in water, marine and offshore environments. GGB bearings can be made in many sizes and forms, including thin-walled, thick-walled, flanged, cylindrical, sintered and oil-impregnated, and more. Some popular bearing materials and their benefits include:
Bimetal bearings are able to handle heavy loads and shock loading conditions. Our bimetal bearings have anti-corrosion capabilities and are easy to install, making them ideal for emergency replacements. GGB-CBM® thin walled bearing is available with stainless steel, carbon steel or bronze backing.
Designed for harsh operating conditions, the AuGlide™ lead-free bearings feature a bimetal composition—steel backing and a bronze overlay—that earns RoHS compliance. They support high specific loads and offer superior performance under oscillating movements. Among many uses for these products, AuGlide™ bimetal bearings will most notably benefit transmissions and truck brakes as well as agricultural, mechanical handling and lifting applications. They boast a high load capacity and very good resistance to fatigue strength at high temperatures.

Bronze is a versatile and commonly used material because it comes in many alloys and compositions. Bronze bushings (also called bronze bearings or solid bronze bushings) are hard and strong, as opposed to softer brass bushings. Bronze bushings have long lifespans and resist shock, impact, wear and corrosion. They require an external lubricant, for example grease or oil, at installation and during operation to reduce friction and wear.
according to ISO 4379
GGB-BP25, GGB-FP20 and GGB-SO16 sintered bearings are used in environments when high speed operation is required, and in limited-space and variable-load applications. These pressed-metal bearings have large pores that are can be filled with lubrication, which is then released under applied force. Oil-impregnated sintered bronze bearings and sintered iron bearings offer maintenance-free operations and are suitable for complex shapes.
PyroSlide™ 1100 high temperature powder metal bearings comprise of a corrosion resistant powder metallic matrix and a homogeneously distributed solid lubricant enabling superior surface engineering performance in extremely high temperatures applications, withstanding operating temperatures of up to 800 degrees Celsius / 1475 degrees Fahrenheit. PyroSlide™ 1100 helps to improve tribological performance (most importantly reducing the coefficient of friction and the wear rate) in applications exposed to elevated temperatures and/or corrosion risk. Typical applications include exhaust after-treatments, industrial and domestic ovens, natural gas/petrochemical valves, heavy-duty engines and more.
