Timken Tapered Roller Bearings Guide
Product Description
The NA48290SW / 48220D TNASWE tapered roller bearing features a double-row tapered roller design with two single inner rings and a double outer ring. The extended inner ring face design provides direct inner-ring contact, eliminating the need for a separate cone spacer and creating a compact bearing configuration. The inner ring lubrication slots improve lubricant flow, while the built-in clearance design ensures stable load distribution, reliable performance, and consistent operation for fixed and floating bearing applications.
The NA48290SW / 48220D TNASWE bearing is widely used in industrial equipment, heavy-duty gearboxes, construction machinery, mining equipment, and other applications where reliable load support, easy installation, and long service life are required.
