Timken Tapered Roller Bearings Guide
Product Description
The NP446605 / NP930308 TNASW tapered roller bearing features a double-row tapered roller design with two single inner rings and a double outer ring. The inner ring front faces are designed with chamfers and lubrication slots, providing improved lubrication performance and reliable operation under demanding conditions. The extended cone front faces abut directly, eliminating the need for a separate inner-ring spacer. This non-adjustable design is supplied with built-in clearance, ensuring stable load distribution and consistent performance for fixed and floating bearing applications.
The NP446605 / NP930308 TNASW 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.
