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.
With the electric vehicle market growing and more electric cars on the road than ever before, HVAC compressor design engineers are faced with unique challenges.
There is pressure to:
Development costs are rising significantly as designs are moving to larger-sized scroll and rotary compressors. Electric car batteries are big and heavy, and they make it incredibly difficult when attempting to find space and weight savings during the design process. Not only the thermal management of the cabin, from cooling to heating (the engine will not heat the cabin anymore) needs to be managed. Also, the cooling of the engine and the batteries require engineered solutions. Additionally, the batteries require either pre-heating or pre-cooling.
The decarbonization of road transportis an essential target for :
This puts pressure on design engineers to increase efficiency of their compressors by reducing weight and size, as well as optimizing friction management and consequently increasing durability of their compressor.
Nowadays, with the increase of electrified vehicles and overall noise reduction, the noise inside the car cabin is more and more related to embedded components. During the car development, also compressor suppliers are consequently asked by car manufacturers to reduce noise created by their compressor. Noise reduction has consequently become an important challenge in the design process of the compressor.
The heat generation of the shaft is a critical point of any compressor. To prevent the risk of shaft seizure, the heat generation of the shaft must be controllable.
Multiple national lockdowns continue to slow or even temporarily stop the flow of raw materials and finished goods, disrupting manufacturing globally. In addition, many companies have laid off staff or lost employees due to COVID.
Manufacturing companies are nowadays forced to reconsider their supply chains and become more resilient, collaborative and networked with their suppliers and consider localizing their supply chain to a certain degree which will help them also to reduce their CO2 footprint.
Design engineers can partner with us early in the design phase to assure reliable, cost-effective solutions with shorter lead time. We commit to sharing our tribological expertise and friction management expertise. With many years of experience in industrial compressor applications and partnering with major global compressor manufacturers and millions of bearings shipped yearly with exponential growth rates for compressor bearings, the design engineer can rely on GGB solutions. This will allow you to develop an optimized compressor, avoid warranty claims and to stay ahead of competition in a rapidly changing world.
GGB’s maintenance-free materials offer excellent low friction properties that absorb the impacts of high loads and increase durability.
Plain bearings and polymer coatings solutions offer low NVH components compared to roller bearings and can significantly reduce size, weight, and absorb vibration.
Power loss for increased output and volumetric efficiency can be reduced even at low speed/high pressure conditions. The materials offer high temperature resistance to accommodate the continuous operation needed for heating and/or colling of batteries.
GGB offers a wide range of lead-free and grease-free surface materials that comply with RoHS directives as well as with the EU End of Life Vehicle (ELV) and the restriction of Hazardous Substances (RoHS) directives. Our solutions offer sustainability that can help reduce your carbon footprint, removing heavy bulky or greased materials, but can also replace hard chrome and NMP in new compressor designs.
By working with you at the very start of the design process, we can leverage our tribological expertise and in-house R&D capabilities to review and ensure that the bearing and surrounding components are the most cost-effective.
