DX10 with DuraStrong technology, a steel-backed bearing material from GGB, is designed specifically to extend the lifecycle of Class 7 and 8 heavy-duty truck kingpins. The company says the new bearings function well in greased or oiled conditions with high loads, high temperatures and contamination, making them suitable for replacing rolling-element, bimetal or bronze bearings to improve wear performance.

Produced using a proprietary polymer processing technology, the lead-free bearings feature abrasion-resistant DuraStrong sliding surfaces designed to withstand harsh environments, according to GGB; they also provide higher load capacity, greater heat resistance and better wear rates than conventional kingpin bearings, particularly in abrasive conditions. The company says the bearings also offer excellent chemical and erosion resistance, as well as good fatigue strength.

DX10 is available as cylindrical bearings, with or without lubrication grooves, oil holes or lubrication pockets, as well as thrust washers. In addition to kingpins, potential applications include piston pumps, agricultural and construction equipment, lifts and cranes, automotive oil pumps and as small reciprocating bearings.
