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.

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.

Polyurethanes are used in the manufacture of nonflexible, high-resilience foam seating; rigid foam insulation panels; microcellular foam seals and gaskets.

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.

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.

Best lubricant forbearings

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'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.

High Speed Bearing Oil

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.

An important distinction to make is that self-lubricating bearings are not bearings that come pre-applied with grease or oil lubricant – these bearings are instead referred to as prelubricated bearings. Prelubricated bearings will require relubrication at some point in their service life. An example of a prelubricated bearing is our DX® low friction bearing which is marginally lubricated with grease.

Self-lubricating bearings work by having lubricant impregnated within the sliding layer of the bearing. This lubricant can either be liquid (oil) or solid (graphite, MoS2, lead) based on the requirements of the application (such as operating temperature). As the bearing operates, the lubricant is released through pores in the sliding layer, lubricating the bearing surface. The lubricant is uniformly dispersed throughout the sliding layer and thus there is no reduction in low friction bearing performance, even if the sliding layer becomes worn. A “running-in” surface is also usually included at the top of the sliding layer to provide low friction bearing performance at start up before the impregnated lubricant reaches the bearing surface.

Due to this, self-lubricating bearings are also referred to as maintenance-free or greaseless bearings as they require no relubrication or grease. An example of a self-lubricating bearing is our GGB-CSM® greaseless bearing.

Self-lubricating bearings, as the name suggests, provide their own lubrication during operation without requiring application of grease or oil lubricants.

GGB has been putting the world in motion for over 120 years with industry-leading tribological bearings, coatings and assemblies.

Self-lubricating bearings eliminate the need for maintenance, lowering labor costs, and increase the service life of aerospace applications. An amazing example of the versatility of self-lubricating bearings in the aerospace industry is the use of DU® anti friction bearings in NASA’s Curiosity rover, which has been exploring the red planet since 2012.

The aerospace industry requires low friction bearings with excellent wear resistance to help reduce labor costs. Additionally, many areas of an aircraft are difficult to access for service and thus benefit from components with long service lives, namely self-lubricating bearings.
