For manufacturers of construction and other off-highway equipment, GGB fiber reinforced composite bearings are a greaseless, maintenance-free solution with an extended service life. Our bearings provide superior performance and lower cost of ownership without the need for complex automated greasing systems.
In eliminating the need for lubrication, GGB bearings give customers the advantage of a more environmentally friendly operation. Our self-lubricating bearings are clean, lightweight, and environmentally friendly, providing a more reliable performance than traditional greased bronze bearings.
Used in a wide range of construction equipment, GGB bearings and shaft bearing assemblies deliver high reliability under the most extreme conditions in applications such as heavy-duty earth-moving and digging equipment, graders, excavators, concrete pumps, pile drivers, and lifting equipment such as fork lifts and pallet trucks, scissor lifts, access platforms in addition to various types of cranes and container handling systems.
ATI Inc. manufactures modular track systems for heavy equipment. These track systems are subjected to enormous loads, both from the weight of the equipment itself as well as shocks from traversing inhospitable terrain. For bearings that stand up to these extreme conditions, ATI Inc. uses GAR-MAX® fiber reinforced composite plain bearings to provide good friction and wear properties under slow-speed oscillating or rotating movements.
In 2009, WILBERT Kranservice GmbH introduced Europe’s strongest luffing jib tower crane. Since the displacement of the swinging jib precludes lubrication, the Wilbert engineering team uses GGB’s GAR-MAX® fiber reinforced composite plain bearings for their self-lubricating, maintenance-free properties and excellent resistance to shock, misalignment and contamination.
Machine downtime is time-consuming and costly for equipment owners whether it’s for a difficult repair, a bearing replacement or even just to lubricate a joint. GGB has worked with major off-highway OEMs and the Advanced Manufacturing Institute (AMI) to develop a shaft-bearing assembly called SBC - Sealed Bearing Cartridge SBC Sealed Bearing Cartridge, aiming to reduce this maintenance time. SBC is proven to outperform conventional greased bronze, hardened steel and rolling-element bearings for demanding applications typically found in off-highway, construction and earth-moving equipment.

Improved performance and service life
Lower system costs
GGB bearing experts are available to provide solutions to meet each application’s specific needs with a vast range of standard or custom bearings. GGB bearings offer excellent performance over a wide range of load, speed and temperature conditions and since lubrication is eliminated, equipment no longer needs to be taken out of operation to be serviced, resulting in reduced maintenance costs, substantial savings and an environmentally friendly product.
