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.
GGB's Metal-Polymer Bearings for Automotive Applications
Mounted on the engine crankshaft, isolator pulley dampers transmit torque to the rubber belt that drives the various engine accessories such as the alternator, the HVAC compressor and the oil and water pumps.
Out-of-balance forces generated by the pistons in the engine, particularly at low idling speeds, transmit asynchronous vibrations to the distribution belt which can ; be felt by the occupants in the car, create noise and reduce the service life of the belt.
To support the belt load applied to the pulley, to reduce NVH (Noise, Vibration and Harshness) and to increase belt life, isolator pulley dampers are fitted with GGB DP11 metal polymer self-lubricating plain bushings.
The structure of GGB DP11 self-lubricating bearings consists of a strong steel backing, to which is bonded a porous bronze sinter interlayer impregnated and overlaid with a PTFE enriched wear resistant bearing layer.
This highly resistant composite bearing structure can withstand specific loads of up to 250 MPa / 36 000 psi, sliding speeds up to 2.5 ms-1 / 500 fpm and temperatures up to 280°C / 536°F.
In isolator pulley damper applications, the excellent antifriction properties of GGB DP11 self-lubricating bearings provide the following benefits:
