The excellent low friction and high wear resistance performance of GGB metal-polymer bearings make them ideal for hundreds of applications in numerous and diverse industries. Depending upon application requirements, metal-polymer composite bearings can be produced in many shapes and sizes.
GGB's Engineered Plastic Polymer bearings provide excellent wear resistance and low friction in both dry and lubricated operating conditions over a wide range of applications. Engineered plastic bearings are made from thermoplastic bearing material processed by injection moulding. This production method enables us to produce unlimited dimensions in accordance to our standard, and also parts with special designs and features.
GGB's Fiber Reinforced Composite products typically consists of a filament-wound, fiberglass-impregnated, epoxy backing with a variety of low-friction wear-resistant bearing linings. These self-lubricating fiber reinforced composite bearings are particularly effective in applications where the relative motion is not sufficient to promote circulation of the oil or grease used with more conventional bearings. GGB Fiber Reinforced Composite bearings are available as bushes, plates, bearing segments and special forms, depending on the particular material type.
Bimetal and metal bearings offer excellent corrosion resistance in industrial outdoor applications and in water, marine and offshore environments. GGB offers a broad range of sizes, forms and materials in monometallic and bimetallic bearings.
Engineered as a solution to conquer misalignment reduction when high demands are placed on bearings, GGB's UNI, MINI and EXALIGN® self-aligning shaft bearing assemblies offer improved equipment performance under standard bearing assemblies by reducing stress and friction. Offering superior performance in a wide variety of applications, GGB's self-aligning assemblies are available in both standard and custom configurations.
GGB has been putting the world in motion for over 120 years with industry-leading tribological bearings, coatings and assemblies. From Polymer Coatings and Metal-Polymer bearings to Fiber Reinforced Composite bearings and self-aligning shaft bearing assemblies, our solutions are specifically designed to reduce friction and optimize performance and durability.
Tribology is the science of wear, friction and lubrication, and encompasses how interacting surfaces and other tribo-elements behave in relative motion in natural and artificial systems. This includes bearing design and lubrication.
GGB’s TriboU is intended to provide the working engineer, who may or may not be a user of GGB’s surface engineered solutions, to understand and implement basic tribological concepts in the design, manufacture and use of industrial equipment.
At GGB, we aren’t afraid to take risks for our customers. We are passionate about the work we do and believe that same passion contributes to the level of innovation that can enhance human potential. We take pride in working closely with customers in the early stage of a design to think broadly and boldly, and to expand beyond traditional surface engineered solutions. We offer reliable partnerships based on trust, compassion, determination, collaboration and respect.
GGB seeks out collaborative, long-term relationships with each one of our customers. Our diverse expertise gives us a deep understanding of the challenges you face. When you partner with us early, our GGB engineering team is able to review your assemblies and make sure both the bearing and surrounding components are optimized for performance and cost-effectiveness.
Mining is a global industry that serves as the critical source behind the raw materials needed to maintain and improve standards of living for people everywhere. From road construction and the automobiles that drive on them to hospital equipment and computers, our world depends on the outputs that come from mining.
However, as demand for these resources increase around the globe, the mining industry has had to dig deeper mines to find higher-grade ore reserves to keep up. Deep, underground mining is more expensive because more energy is needed to excavate raw materials. This is due to increased demands for more ventilation and air conditioning being needed to the increased difficulties of having to carry materials a further distance away. Plus, because pollution and emissions are health risks to miners, regulations are becoming increasingly more restrictive. These rising energy costs (in addition to social and geopolitical issues) are putting mining companies under a lot of pressure to control costs, heighten efficiencies, and improve safety.
There are four main methods for mining
Working with us early in the design phase assures reliable, cost-effective solutions with shorter lead times. As you get started designing and concepting your project, you have plenty of options given our wide array of bearing solutions. ROHS compliant and eco-friendly, here’s a first look at some of the innovations we can bring to your design and manufacturing efforts.
Providing maintenance-free and impact tolerant performance in harsh environments, our metal- and bimetal, metal-polymer and fiber reinforced bearings are grease-free solutions perfect for use in axial roll units, conveyor belts and hoist systems for vertical shaft mines. With an inert nature that makes them suitable for corrosive environments, our composite fiber reinforced bearings feature low-friction, wear-resistant linings and accommodate high static and dynamic loads—ideal for a variety of applications such as swiveling belt conveyors for cutting head machines, crawler track systems, and couplers for equipment attachments.
Ideal tribological solutions provide excellent wear life with improved corrosion resistance for smooth operation in harsh environments.
GGB bearings reduce shaft costs by eliminating the need for hardening and machining grease paths. Their compact, one-piece construction provides space and weight savings and simplifies assembly compared to roller bearings.
Lead-free GGB bearings comply with increasingly stringent environmental regulations such as the EU ELV directive and RoHS directive. Seamless operation and higher productivity with less downtime can be achieved by GGB`s maintenance-free solutions.
Thanks to our global manufacturing plants we can offer short transport ways that reduce CO2 footprint.
Improved system performance and service life
Superior wear resistance and high shock load capacity provide extended bearing service life and improved reliability. Additionally, excellent low friction properties reduce power losses for improved equipment performance.
GGB can provide customers with a viable engineered solution, working alongside global OEMs and their distributors. Our application and tribology experts can develop a design proposal, and from prototype delivery to serial production and assembly, our experts will accompany you.
