Tapered roller bearings in the NTN J series are built to handle combined radial and axial loads. The cone and cup design creates linear contact that spreads the load, giving the bearing high capacity. They are common in gearboxes, wheel shafts, and industrial machinery where rigidity and precision matter. MR Industrial Accessories supplies this series.
The part number tells you what you are getting. In a code like 4T-495AS/493, the 4T- prefix marks the NTN J series, 495AS is the cone, and 493 is the cup. Suffixes, when present, can point to contact angle or special tolerances. Always confirm both numbers and check the dimension tables before ordering.
These bearings show up in gearboxes, speed reducers, transmission shafts, rollers on road and agricultural machines, and metalworking equipment. You will also find them in pumps, fans, and material handling systems. Their ability to take combined loads suits demanding applications where reliability is critical.
Selection depends on radial and axial load, rotation speed, and the environment. Mounting needs precise alignment and a proper fit between cone and cup. Choose grease or oil based on temperature and speed. Sealing keeps lubricant in and contaminants out. Poor mounting can cause early wear or failure, so follow the manufacturer's instructions.
Tapered roller bearings are interchangeable across brands when dimensions and load capacity match. When replacing, verify the complete part number and tolerances. The NTN J series meets international quality standards. If you need an equivalent, contact MR Industrial Accessories with the original part number.
