The tapered roller bearing is a component designed to support combined radial and axial loads. Its internal geometry, with inclined rollers and raceways, distributes forces in applications where precision and load capacity are critical. It is used in industrial machinery, transmission equipment and rotating systems that require a tight fit and careful alignment. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina.
The designation of this series is interpreted from its numbers and letters. For example, 33212U3EE corresponds to a tapered roller bearing of the 332 series, with a suffix U3 that indicates a special execution and EE that refers to the type of sealing or cage. The examples 33213U3EE, 33214U3EE, 33215U3EE, 33216U3EE and 33217U3EE follow the same logic, varying the size according to the numeric code.

These bearings are used in industries such as food, metallurgy, mining and agriculture, in equipment such as conveyor belts, gearboxes, transmission shafts and process machinery. In Argentina, they are common in manufacturing plants and workshops that require robust components to withstand heavy loads and demanding working conditions. Their tapered design makes them suitable for assemblies where axial clearance must be controlled and smooth operation guaranteed.
To select the correct bearing, take into account the radial and axial load it must support, the rotation speed and the environmental conditions. The EE seal protects against contamination, while the U3 suffix may indicate a specific internal clearance. During assembly, it is essential to verify shaft alignment and apply adequate lubrication to maximize service life. Correct axial retention and preload adjustment also influence performance.
As for equivalents, NTN tapered roller bearings can be interchanged with those of other recognized brands, as long as the main dimensions and the type of execution match. It is important to compare not only the numeric code but also the suffixes, since these define characteristics such as sealing or internal clearance. If you have doubts, our technical team can advise you to find the compatible part.
