The tapered roller bearing is a component designed to withstand combined radial and axial loads. Its cone and cup geometry allows linear contact that distributes the load better. It is used in applications with significant stresses and controlled misalignment. MR Accesorios Industriales sells the NTN brand in Buenos Aires, Argentina, with more than 80 years of experience in the field. If you need a specific size, write to us on WhatsApp and we'll quote it for you.

The 4T series designation includes a numeric prefix and suffixes that indicate manufacturing characteristics. For example, in 4T-30305D, the prefix 4T identifies the series, while the final letter D indicates a design modification, such as the contact angle or surface treatment. The examples 4T-30309D, 4T-30310D and 4T-30311D follow the same pattern: the central number defines the size and load capacity. Knowing these codes helps 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, reducers, wheel axles, agricultural machinery and material handling equipment. Their ability to withstand combined loads makes them suitable for bevel gears and applications with tilting moments. MR Accesorios Industriales sells them to supply both workshops and industrial plants that require reliable replacements.

To select a tapered roller bearing, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. Mounting requires precise alignment and adequate internal clearance, which is adjusted using shims or nuts. Lubrication can be with grease or oil, depending on the application. Sealing is critical to prevent contamination and lubricant loss. If the bearing works in pairs, respect the arrangement and preload indicated by the manufacturer.

There are equivalents between brands for tapered roller bearings, but it is essential to verify the exact tolerances and dimensions.
