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 where power must be transmitted precisely, such as gearboxes, wheel axles and industrial equipment. At MR Accesorios Industriales we quote them with the exact designation you need.
The designation of these bearings combines numbers and letters that identify dimensions and characteristics. For example, in 32308U2FD and 32312U2FD, the 323 series corresponds to single-row tapered rollers with standardized dimensions. The U2 suffix indicates a treatment or design variant, while FD usually refers to a sealing or lubrication configuration. To correctly interpret each code, it is key to follow the manufacturer's catalogue and consult with our technical team.
In Argentine industry, these bearings are found in mining, cement, steel, food and transport equipment. They are used in gearboxes, conveyor belt rollers, machine tool spindles and heavy vehicle axles. Their ability to support combined loads makes them ideal for helical gears and applications with tilting moments. MR Accesorios Industriales supplies them to plants and workshops throughout the country.
To select a tapered roller bearing, you must consider radial and axial load, rotation speed and environmental conditions. Mounting requires precise alignment and proper adjustment of axial clearance, which is regulated by lock nuts or shims. Lubrication can be with grease or oil, and the sealing must be chosen according to contamination and temperature. Incorrect mounting shortens service life, so we recommend following the manufacturer's instructions.
Tapered roller bearings are interchangeable between brands if the main dimensions and contact angle match. When replacing a part, it is essential to verify the complete code and tolerances. If you have the code from another brand, we can tell you the compatible equivalent. We can also quote the exact size you need. Write to us on WhatsApp with the code or dimensions and we will quote you shortly.
