The NTN 4T series tapered roller bearing is a component designed to support combined radial and axial loads. Its tapered geometry allows linear contact that distributes the load and offers high load capacity. It is used in applications where rigidity and precision are required, such as transmission cases, gear reducers and industrial equipment. At MR Accesorios Industriales we sell NTN's 4T series, with designations that combine numbers and letters to identify each assembly.

The designation of NTN's 4T series consists of a prefix and a pair of numbers that identify the cone and the cup. For example, in 4T-LM11749/LM11710, the prefix 4T indicates the design series, while LM11749 corresponds to the cone and LM11710 to the cup. Additional suffixes, such as † or ††, indicate variants in finish or tolerance. Other examples are 4T-LM11949/LM11910 and 4T-LM12749†/LM12711††. Knowing this nomenclature makes it easier to select the right bearing for each application.

These bearings are used in industries such as automotive, metallurgical, food and mining. In Argentina, they are common in gearboxes, wheel axles, speed reducers, mills and transport equipment. Their ability to support combined loads makes them suitable for machinery operating under high demands. MR Accesorios Industriales, with more than 80 years in the market, supplies these sectors with quality-guaranteed NTN bearings.

To select a tapered roller bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Assembly requires precise alignment and proper adjustment of axial clearance, which is regulated by displacing the cup or cone. Lubrication must be suitable for the temperature and speed; grease or oil is recommended depending on the case. Sealing protects against contaminants and retains lubricant, extending service life.

NTN 4T series tapered roller bearings are interchangeable with those of other brands that follow the same international designation, such as Timken, SKF or FAG. However, it is essential to verify dimensions and tolerances to ensure compatibility. When replacing a bearing, compare the complete code and technical specifications. If you have doubts, consult us with the original code and we will tell you the exact equivalence.
