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.

For many decades, the increasing weight of passenger car vehicles has been a headache for strut and shock absorber manufacturers. The reasons behind the previous and progressive increases of car weight are multiple:
In addition to these reasons, and perhaps for the most important reason of a cleaner environment, car weight has and will further rise as manufacturers are obliged to electrify their models to reduce the level of exhaust gas emissions and comply with the latest vehicle emission legislation.
The electrification of a vehicle typically involves the integration of an electric motor, electronic control equipment and battery in different motorization configurations which according to their level of complexity leads to varying reductions in car emissions, for example:
Motorization confirguration: Reduction in Co2
Mild Hybrid 48V: 15 - 20%
Plug-In Hybrid: 50-75%
Battery Electric: 100%
However, this reduction in CO2 is offset by an increase of vehicle weight, in some cases close to 300kg or more, depending on the type of car model and motorization solution that is chosen, for example:
This greater weight has a direct impact on the organs of the suspension and leads automatically to a significant rise in the applied loads on the struts and shock absorbers which incorporate a GGB bushing.
The GGB bushing is located inside the strut and is mounted in the rod guide assembly.
The function of the bush is two-fold.
- Support the radial loads that are applied to the strut from the suspension, loads that vary considerably during cornering, acceleration and braking and also from the road topography under all types of road conditions
- Allow the sliding movement of the piston rod to which is fixed the piston that dampens the vibrations during the extension and compression cycles of the shock.
After analysis of the higher load conditions and taking into account the restriction of not increasing the size of the bushing due to weight and dimensional constraints whilst still maintaining overall life performance, it quickly became apparent that a new bearing solution was required.
To meet these requirements, the metal-polymer GGB DTS10® is the ideal bearing solution for this new generation of struts as its unique composite structure offers:
- A homogenous anti-friction overlay enriched with PTFE and wear resistant fillers with a minimum thickness above the bronze layer of 0.1mm
- Steel backing for high mechanical strength
As indicated in the DTS10 Product Brochure, the superior tribological performance of DTS10 compared to other products has been evaluated by multiple tribological trials on test benches in our Research and Development laboratories.

Relative Hydrofatigue Resistance
Trials in the field have further given a confirmation of the benefits of GGB DTS10® in strut applications which are:
