GGB Bearing Technology
World's First Metal-Polymer Bearing Turns 60 This Year
THOROFARE, NJ--(Marketwired - March 30, 2016) - Â
- Longevity attests to the DUÂ® Â bearing's revolutionary design
- Created the category of metal-polymer plain bearings
- Foundational technology for numerous bearing innovations in last 60 years
Sixty years ago, GGB Bearing Technology's predecessor company, U.K.-based Glacier Metal Company, revolutionized the bearing industry with the introduction of DUÂ® , the world's first self-lubricating metal-polymer plain bearing material.
DUÂ® bearings combine the high load capacity and dimensional rigidity of lubricated metallic bearings with the performance and economic benefits of self-lubrication. The structure of the bearings consists of a rigid steel or corrosion-resistant bronze backing (DU-B), which provides mechanical strength, while a porous sintered bronze interlayer impregnated with a homogeneous mixture of PTFE and lead provides low friction and high wear resistance.
The low friction of the bearings reduces power losses for improved energy efficiency, while the wear-resistant bronze layer provides extended service life. Being self-lubricating, the bearings require little to no maintenance. However they can also be used with lubricant to prevent potential shaft/bearing seizure under boundary conditions.
The compact, lightweight design and thin-wall construction of the bearings provide space and weight savings, and because there are no moving parts or metal-to-metal contact, the bearings are quieter. In addition, assembly can be done quickly and easily without costly mounting tools.
Today, GGB produces millions of DUÂ® bearings for use in numerous applications in a wide range of industries. These include agricultural and other off-highway equipment; automotive including trucks; aviation; business machines; garden, lawn and outdoor equipment; hydraulics and valves; homes appliances and consumer goods; material handling; medical and dental; marine; packaging; recreational vehicles; railway equipment; textile equipment; and tools.Â
When they were introduced, DUÂ® bearings represented a major technological breakthrough, becoming an industry standard and establishing GGB as the global leader in self-lubricating, metal-polymer plain bearings. They also served an important foundational role in the subsequent development of a range of stronger, more durable and environmentally friendly lead-free, metal-polymer bearings.
These include marginally lubricated DX Â® bearings for grease or oil lubricated applications (1965); HI-EX Â® marginally lubricated bearings for high-temperature applications (1986); DP4Â bearings for automotive shock absorbers and other hydraulic applications (1995); DP31Â bearings for improved performance under lubricated conditions, wear resistance, fatigue strength and low friction (2003); DX Â® 10 bearings for Class 7-8 trucks; DP10 Â and DP11 bearings for superior performance under marginally lubricated and dry running conditions (2010); and DTS10 Â® machinable metal-polymer bearings for the fluid power and compressor markets.
