GGB tribological solutions move the industrial world one step closer to the future. Our products are used in tens of thousands of critical applications every day—around the planet. Our goal is to provide reliable, maintenance-free surface solutions for almost any application—no matter where those demands take our products.
GGB's diverse polymer coating solutions encompass some of the most state-of-the-art coating technologies available. Our TriboShield® product line includes seven standard formulations that cover the full spectrum of mechanical, thermal and chemical capabilities offered by today's coating materials. They can also be applied to nearly any surface, regardless of shape or material, making their potential almost endless. And when it comes to working with and enhancing the performance of your existing bearing and polymer coatings solutions, our TriboMate product line is specifically designed to be paired up— all leading to enhanced performance.
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.
Find out how GGB's antifriction products and solutions offer improved bearing performance for your application.
GGB's antifriction plain bearings and bushings provide numerous benefits across a wide range of industries and applications, including aerospace, automotive, construction, energy, industrial, recreational and many more.
Over 60 years ago, GGB invented the original antifriction bearings and bushings DU® and DX® that quickly became the industrial standard in high performance plain bearing solutions.
With the constant increase in customer demands and expectations for superior plain bearing performance, GGB's bearing range now includes over 50 distinctive antifriction bearing types including for example, DP4, HI-EX®, GAR-MAX®, HSG, EP® range, GGB-CSM® and GGB-CBM® products.
The range of self-lubricating GGB bearing products are ideally suited to run under dry conditions offering to the final customer complete maintenance-free operation.
The main advantages are:
Self-lubricating bearings are also necessary when operating under boundary or marginally lubricated regimes.
These regimes occur when the thickness of the lubricant film is too low to avoid metal-to-metal contact and wear between the bearing and the sliding surface due to a combination of high loads, low speeds and insufficient lubricant viscosity.
For equipment running under periods of low speed idling and frequent stop-start operation, the self-lubricating properties of GGB bearings significantly improve machine efficiency by reducing bearing wear and the increase of clearances, noise and the risk of eventual equipment seizure.
The majority of GGB bearings contain polytetrafluoroethylene (PTFE) in the sliding layer.
One of the characteristics of PTFE is exceptionally low coefficient of friction which reduces bearing friction, bearing wear and, most importantly, energy consumption.
The overall efficiency of equipment and machinery is therefore increased for reduced power input and a higher power output.
The proprietary GGB bearing structure and overlay compositions include special anti-wear additives for high wear resistance to give extended service lives.
The inert nature of the Fiber Reinforced Composite and Engineered Plastics Bearings ranges are suited to many corrosive environments.
Generally requiring inexpensive techniques and tooling, GGB bearings simplify assembly and can be mounted directly into the housing without the need of cooling or heating equipment.
Compared to roller bearings, plain bearings offer a greater contact area for a higher load capacity, an excellent resistance to shock loads and are more tolerant to edge loading.
The compact one piece design of plain bearings allows a significant reduction in housing dimensions for substantial space and weight savings.
Noise is reduced with the absence of internal moving parts and the plain bearing conformable liner offers superior damping properties.
