Timken Tapered Roller Bearings Guide
Product Description
The NA776 / 774CD Timken TNA tapered roller bearing features a double-row tapered roller design with two single inner rings and a double outer ring. The extended inner-ring front faces are designed to abut directly, eliminating the need for an inner-ring spacer and providing a compact, pre-set bearing configuration. This non-adjustable design is supplied with built-in clearance, ensuring reliable operation, stable load distribution, and consistent performance under demanding conditions.
The NA776 / 774CD TNA bearing is widely used in industrial equipment, heavy-duty gearboxes, construction machinery, mining equipment, and other applications where reliable load support, easy installation, and compensation for shaft expansion are required.
