DX10 with DuraStrong technology, a new steel-backed bearing material from GGB (formerly Glacier Garlock
Bearings), is designed specifically to extend the life cycle and reduce maintenance costs of Class 7 and 8 heavy-duty truck kingpins.
The new bearings function particularly well in greased or oiled conditions with high loads, high temperatures and contamination, making them ideal for replacing rolling-element, bimetal or bronze bearings to improve wear performance. In addition to kingpins, potential applications include piston pumps, agricultural and construction equipment, lifts and cranes, automotive oil pumps and as small reciprocating bearings.
Produced using a proprietary polymer processing technology, the lead-free bearings feature tough, abrasion-resistant DuraStrong sliding surfaces to withstand harsh environments. They also provide higher load capacity, greater heat resistance and significantly better wear rates than conventional kingpin bearings, particularly in abrasive conditions. Additionally, GGB's new bearings offer 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.
Maximum sliding speed is 500 fpm (2.5 m/s) greased and 2,000 fpm (10 m/s) with oil lubrication. Maximum PU factor is 80,000 psi x fpm (2.8 N/mm² x m/s) both greased and with oil lubrication. Coefficient of friction is 0.01-0.10 greased and 0.01-0.06 with oil lubrication. Temperature range is -40ºF to +350ºF (-40ºC to +175ºC). Maximum static load is 36,000 psi (250 N/mm²), and maximum dynamic load is 20,000 psi (140 N/mm²).
