Heavy-duty bearings and shaft bearing assemblies used in a wide range of construction and off-highway equipment including heavy-duty earth-moving and digging equipment, graders, excavators, lifting equipment and others.
In order to match manufacturers of construction and off-highway equipment expectations, GGB offers fiber reinforced composite bearings. These filament wound bearings are a greaseless, maintenance-free solution with an extended service life. They provide superior bearing performance and lower cost of ownership without the need for complex automated greasing systems.
Learn about all benefits offered by GGB construction bearings.
Cylindrical bearings are plain bearings that are cylindrical in shape and contain no moving parts.
They are also referred to as bushes, bushings or sleeve bearings. These bearings may be solid (metal, plastic, or composite bearings) or wrapped (metal-polymer bearings). Cylindrical plain bearings accommodate heavy radial loads and operate at lower speeds than roller bearings.
Cylindrical bearings could also refer to cylindrical roller bearings. These bearings feature moving roller rows and a metal or plastic cage. These cylindrical roller bearings accommodate heavy radial loads and can operate at high speeds.
Learn how you can replace roller bearings by GGB cylindrical bearings.
GGB revolutionized the bearing industry 60 years ago with the introduction of DU® bearing, the world’s first self-lubricating, metal-polymer plain bearings.
DU bearings made of this material combined the high load capacity and dimensional rigidity of lubricated metallic bearings with the performance and economic benefits of self-lubrication. Their success lies in the unique composite bearing structure comprised of a steel backing for mechanical strength and a porous sintered bronze interlayer impregnated with PTFE and lead for high wear resistance and extremely low friction properties.
This structure provides the following benefits:

Plain bearings consisting of a fiber-reinforced composite structure.
Filament wound bearings, also known as filament bearings, are plain bearings consisting of a fiber-reinforced composite structure with the radial and axial strength to support high loads. The sliding layer consists of continuously wound PTFE and high-strength fibers while the backing consists of continuous wound fiberglass.
These filament wound bearings have an inert nature making them ideal for applications in corrosive environments such as sea water and acidic environments. Additionally, the filament wound materials are resistant to a much greater range of chemicals than metallic bearings.
Learn more about GGB's wide range of fiber reinforced composite bearings.
Flanged bearings are plain bearings with a flange at one end to facilitate installation and accommodate both radial and axial thrust loads.
Flange bearings are generally made of metal-polymer or engineered plastics but can be made from fiber reinforced composite as well.
Plastic double-flanged bearings, such as GGB's FLASH-CLICK® Solid Polymer Double Flange Bearings are plain bearings with a flange at both ends. They are particularly well suited for applications where a two-sided flange is needed as a thrust surface.
Half-bearings are essentially regular cylindrical bearings split into two halves.
These bearings are used in engines found in automobiles, boats, construction machinery, pumps and even power plants.
Several GGB bearing materials can be made to order as half bearings, among which :
Plain bearings consisting of a metal backing onto which is bonded a bearing layer of PTFE or similarly lubricious material.
This structure results in these bearings having low friction and wear performance while also having high load capacity due to the metal backing. Metal-polymer bearings are available in self-lubricating and pre-lubricated varieties.
Find out more about GGB's line of metal-polymer bearing solutions.
Alternative term for roller bearings.
Needle bearings have cylindrical rollers that are much larger than the bearing diameter. This provides a larger surface area in contact with the race than regular roller bearings, giving needle bearings a high radial load capacity. Needle bearings generate a higher amount of friction than other roller bearings and are used in low speed applications as a result.
Learn more about the advantages offered by GGB plain bearings over the roller or needle bearings.
Plain bearings injection molded from a variety of thermoplastic resins compounded with reinforcing fibers and solid lubricants.
Plastic plain bearings are lighter and more affordable than their metal counterparts while still offering low wear and long service life.
Plastic bearings and bushings are often found in applications requiring lightweight bearings such as aircraft interiors and vehicle side steps. Plastic bearings are also known as polymer or solid polymer bearings.
Learn more about GGB's wide range of innovative engineered plastic bushings and bearings.

Roller bearings generally have low friction, high radial load capacity, and the ability to operate at high speeds.
Learn more about what are the main differences between a plain bearing and a roller bearing.
Sealed Bearing Cartridges with fiber reinforced composite bearings in a steel shell.
GGB sealed bearing cartridges are designed for use in heavy-duty construction and agricultural equipment applications. The metal outer shell prevents contaminants from affecting the performance of the fiber reinforced composite bearing, making sealed bearing cartridges ideal for applications in harsh, dirty environments.
Find out about how SBC with HSG helped eliminate corrosion in the rubber track systems of tractors and harvesters.
Bearings that do not require additional lubrication, including metal-polymer bearings with lubricious liners, oil-impregnated metal bearings, and plastic and composite bearings with integral solid lubricants.
Self-lubricating bearings are ideal for applications where bearing maintenance cannot be afforded or would prove difficult.
Examples of GGB self-lubricating bearings are:
Sintered bronze bearings are mono-metallic bearings produced by a powder metallurgy process and impregnated with oil.
The metallic structure supports and transfers the mechanical loads while the lubricant reduces friction. The impregnated oil can be substituted for other lubricants, depending on the requirements of the application.
GGB's sinter bronze bearings include GGB-BP25 METAFRAM oil impregnated plain bearing.
Linear bearings that feature a low-friction PTFE surface and a sturdy plate backing of either metal or fiber reinforced composite.
Sliding plates are usually found in applications attached to strong structural elements that have unfavorably high coefficients of friction. When the structural element slides against another element, the low-friction PTFE serves as the contact between surfaces. Multiple sliding plates can be used between sliding elements to have PTFE on PTFE contact, resulting in even lower friction performance.
GGB offers sliding plates as a form of our popular bearing solutions, such as the DP4-B metal-polymer bronze backed PTFE bearing.
Rolling-element bearings designed to support primarily axial loads that generally consist of two outer grooved plates and an inner caged rolling element.
Some rolling-element bearings are designed to exclusively support axial loads and cannot be subjected to radial loads at all.
These thrust bearings are found in the gear sets of car transmissions where they support the high thrust loads produced by the gears.
An assembly used to house metal-polymer bearings found in applications such as pumps and motors.
Thrust plates provide a tight tolerance control on gear meshing to promote silent operation in applications.
