NTN tapered roller bearings are components designed to support combined radial and axial loads. Their raceway geometry and truncated cone rollers allow linear contact that distributes the load over a larger surface than ball bearings. They are used in applications with significant stresses and controlled misalignment, such as gearboxes, reducers, wheel hubs and industrial equipment. MR Accesorios Industriales sells the NTN line in Buenos Aires, Argentina, and advises you to choose the correct code.

The designation of these bearings combines a prefix and suffixes that identify the design and manufacturing characteristics. In the 4T series, the prefix 4T distinguishes NTN's tapered roller line. The examples 4T-30306D7FB, 4T-30307D7FB, 4T-30308D7FB and 4T-30312D7FB show the pattern: after the hyphen, the base number (30306, 30307, 30308, 30312) defines the size and load capacity according to standards. The suffix D7 indicates a modification in the internal design, and FB refers to the surface treatment or manufacturing precision. Know the complete code to request the exact bearing.

These bearings are used in industries where combined loads and shocks are frequent. In Argentina, you find them in mill gearboxes, grain conveyors, road machinery, pumping equipment and heavy vehicle transmissions. They are also used in machine tool spindles and rolling mill rolls. Their ability to support axial loads in one direction makes them ideal for paired assemblies. MR Accesorios Industriales quotes the code you need for your equipment.

To correctly select a tapered roller bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Assembly requires precise alignment because these bearings do not tolerate angular misalignment greater than a few arc minutes. Lubrication can be with grease or oil, and sealing will depend on the contamination of the environment. Internal clearance is adjusted during assembly by axial displacement of one of the races. If the bearing works paired, respect the clearance specified by the equipment manufacturer.

Regarding equivalences, tapered roller bearings are identified by their numeric designation and suffixes that may vary between manufacturers. If you bring the code from another brand, we can interpret it and offer you the NTN equivalent. Interchangeability depends on the main dimensions (bore, outer diameter and width) and load capacity. Not all suffixes are equivalent, so it is important to verify the application. At MR Accesorios Industriales we help you find the right reference.
