For equipment that must carry both radial and axial forces at the same time, the NTN J series tapered roller bearing is a standard choice. Its tapered races and rollers distribute the load along the contact line, which supports rigidity and load capacity in industrial machinery, automotive assemblies and transmission systems.

The part number tells you how the bearing is built. Take 4T-368S/362A: the 4T- prefix marks a single-row tapered roller bearing, 368S is the cone (inner ring) and 362A is the cup (outer ring). The S on the cone points to a design variant, while the A on the cup signals a change in tolerances or contact angle. Other suffixes, such as J, define series characteristics like contact angle or cage type.

These bearings appear in gearboxes, reducers, transmission shafts, vehicle wheels, agricultural machinery, mining equipment and transport systems. Because they take combined loads, they suit demanding settings in the metallurgical, cement and oil industries, as well as light and heavy vehicles.

Selecting the right unit starts with the size and direction of the loads, the rotation speed and the operating environment. During assembly, alignment must be precise and axial clearance set through the relative position of the cone and cup. Lubrication has to match temperature and speed, following the manufacturer's instructions. Sealing is equally important to keep contaminants out and lubricant in.

NTN J series bearings interchange with other brands that share the same standardized dimensions. For a replacement, check cone and cup dimensions, contact angle and load capacity. Part numbers differ between manufacturers, but standardized measurements let you find equivalents. To confirm compatibility, send the complete part number or exact measurements and we can help you choose.
