NTN tapered roller bearings are components designed to support combined radial and axial loads, thanks to the inclined arrangement of their rollers and the conical geometry of their raceways. They are used in applications where precision and load capacity are critical, such as gearboxes, wheel axles and industrial machinery. At MR Accesorios Industriales we sell NTN bearings.

The designation of this series combines a base number with the suffix FB, which identifies an execution with specific dimensional and tolerance characteristics. For example, part number 4T-303072FB corresponds to a tapered roller bearing with a 30 mm bore, while 4T-303082FB shares the same bore but with a greater width. The prefix 4T- indicates that it is a special execution within the NTN catalog, with tolerances and clearances defined for demanding applications.

These bearings are used in a wide variety of industries in Argentina, such as automotive, metallurgical, cement and food. They are common in gearboxes, differentials, machine tool spindles, conveyor rollers and mining equipment. Their ability to support combined loads makes them ideal for assemblies where the shaft must rotate precisely under simultaneous radial and axial loads.

To correctly select a tapered roller bearing, take into account the type of sealing required, the internal clearance and the lubrication method. Precise alignment between the cone and the cup is essential to avoid premature wear. In assemblies with bearing pairs, it is recommended to adjust the axial clearance according to the manufacturer's specifications. Lubrication can be with grease or oil, depending on the speed and operating temperature.

As for equivalents and interchangeability, NTN tapered roller bearings can replace those of other recognized brands, as long as the same dimensions and tolerances are respected. It is important to verify the complete part number and the execution characteristics, since small differences in the suffix may indicate variants in the internal design. If you have doubts, ask us with the original part number and we will advise you.
