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.

Zhuhai Gree wanted to take advantage of the benefits of scroll compressors for its air conditioners, but needed to make sure the new technology would be functional and profitable.
Changing technologies in an existing product platform is always a risky proposition and never to be taken lightly — especially when the existing technology is proven to work. Such was the case in 2010 when the world’s largest manufacturer of air conditioners, Zhuhai Gree Electric Appliances, decided to replace their rotary compressors with scroll compressors.
Scroll compressors, which compress the refrigerant in an air conditioner, offer a number of advantages over rotary compressors, particularly for cooling large spaces. Zhuhai Landa, a subsidiary of Zhuhai Gree that focuses on compressors, had never manufactured scroll compressors before, and they brought GGB in at the beginning of the process to identify plain bearing solutions for the main and orbit scroll bearing.
The bearings for this application must provide very good friction properties, heat resistance, durability and wear properties. Because the compressor is a closed system, it’s not possible to access the bearings to perform maintenance. Further, any failure of the bearing would likely result in catastrophic failure of the entire air conditioning unit.
GGB assembled a team of sales and engineering professionals who evaluated the operating parameters and performance requirements, and determined that the DP10 low friction bearing would be the ideal solution.
The DP10 plain bearing consists of a metal backing that is bonded to a lead-free sliding layer made from a blend of PTFE and solid lubricant. With very good dry and oil lubricated performance, low friction and wear resistance, the DP10 offers an excellent combination of performance and price.
Zhuhai Landa subjected the sample bearings to rigorous testing for more than a year, with GGB providing communication and technical support throughout the validation process. Based on the performance of the bearings and GGB’s technical support and delivery capabilities, Zhuhai Landa selected the DP10 low-friction bearings for their new scroll compressor operations. Thanks to GGB’s partnership and assistance over the seven years that the scroll compressor line was in development, its launch was a resounding success.
