The 580/572 Tapered Roller Bearing is a highly reliable component specifically engineered for demanding environments. This single-row bearing set, comprising the 580 cone (inner ring assembly) and the 572 cup (outer ring), is designed to effectively manage combined loads. Its tapered geometry allows it to handle both significant radial forces and high axial (thrust) loads in one direction, making it indispensable for applications where robust load distribution is critical. Precision-manufactured from high-grade bearing steel, the 580/572 offers exceptional durability, low friction, and a prolonged service life. Its separable design facilitates straightforward mounting, dismounting, and maintenance, reducing costly downtime in industrial operations.

As an imperial-sized bearing, the 580/572 features a nominal bore diameter of 3.25 inches (82.55 mm) and an outside diameter of 5.5115 inches (139.992 mm), with a total width of 1.4375 inches (36.513 mm). These dimensions and its superior load ratings make it a versatile solution across multiple heavy-duty sectors. It is extensively used in the automotive industry for wheel hubs, differentials, and transmissions, as well as in heavy industrial machinery, gear drives, and various construction equipment. Whether used in a railroad application or a high-stress conveyor system, the 580/572 Tapered Roller Bearing ensures smooth operation, superior rigidity, and enhanced energy efficiency, providing a cost-effective solution for prolonged operational reliability.
