NTN tapered roller bearings are components designed to support combined radial and axial loads. Their cone and cup geometry allows linear contact that distributes the load better. They are used in applications with significant forces and controlled misalignment, such as gearboxes, wheel shafts and transmission machinery. MR Accesorios Industriales sells this line for the Argentine industrial market, with technical advice to choose the correct designation.

The designation of these bearings combines a base number with suffixes that indicate design characteristics. For example, in 4T-302073DB, the prefix 4T identifies the NTN series, 302073 is the dimensional code and DB indicates a duplex mounting. In 4T-302083DB and 4T-302154DB the pattern repeats: the central number defines the size and the DB suffix the roller arrangement. Knowing these codes helps identify the exact part.

In Argentine industry, these bearings are used in mining, cement, steel and transport equipment. They are also present in gearboxes, overhead cranes, mills and road machinery. Their ability to support combined loads makes them suitable for wheel shafts and demanding transmission systems. MR Accesorios Industriales sells them for plants and workshops that need reliable spare parts.

To select a tapered roller bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Mounting requires precise alignment and adequate axial adjustment to avoid excessive clearance. Lubrication must be the one indicated according to temperature and contamination. Sealing is key to retain the lubricant and exclude particles. These factors ensure long-lasting performance.

There are equivalences between brands: the same size can be found in catalogs of different manufacturers with their own codes. If you have the part number of another brand, we can help you identify the corresponding NTN reference. Interchangeability depends on tolerances and internal design, so it is important to verify the specifications. At MR we advise you to find the right part.
