The double row tapered roller bearing is a component designed to withstand radial and axial loads in both directions, with high load capacity and rigidity. It is used in applications requiring a compact and precise assembly, such as gearboxes, drive shafts and industrial equipment. MR Accesorios Industriales sells the NTN line with technical advice to select the correct designation for each application.
The designation of these bearings combines a prefix and a number that identifies the series and size. Series 4T-4302 and 4T-4303 group double row bearings with different dimensions. Suffixes may indicate features such as the contact angle or the cage type, although these are not detailed in these examples. To correctly interpret each code, it is essential to consult our technical team.
In Argentine industry, these bearings are used in speed reducers, machine tools, mining equipment and cement plants, among other applications that must withstand heavy loads and tilting moments. Their ability to align shafts and absorb misalignment makes them suitable for demanding environments.
To select the right bearing, radial and axial loads, rotation speed, lubrication and the required sealing type must be considered. Assembly must ensure precise alignment and correct fit to avoid premature failure. Lubrication can be with grease or oil, depending on operating conditions.
NTN bearings are interchangeable with those of other recognized brands, as long as the same dimensions and tolerances are respected. If the customer has the code from another brand, we can identify the equivalent and offer the corresponding NTN alternative. Ask us about any particular code.
