NTN CU series tapered roller bearings are components designed to withstand combined radial and axial loads. Their cone and cup geometry allows linear contact that distributes loads better, ideal for applications with significant forces and controlled misalignment. They are used in industrial machinery, automotive and transmission equipment. At MR Accesorios Industriales we quote them via WhatsApp with your part number or size.
The CU series designation is read directly in the part number: for example, 32309CU and 32311CU indicate the size and dimension series. The first digits identify the diameter and width series, while the CU suffix indicates a specific design variant within the NTN line. To select the correct bearing, take into account the bore diameter, outer diameter and width your equipment needs. If you can't find the exact reference, write to us via WhatsApp and we'll quote it.
These bearings are used in a wide variety of industrial applications in Argentina: gearboxes, gear cases, transmission shafts, road machinery rollers, mining equipment, cranes and bridges. They are also present in the automotive sector, in wheel hubs and differentials. Their ability to withstand combined loads makes them suitable for demanding environments, with vibrations and changes in load direction. MR Accesorios Industriales sells them throughout the country.
To correctly choose a tapered roller bearing, consider the sealing type, internal clearance and lubrication. The CU series can be mounted in pairs to achieve precise axial adjustment. Ensuring proper alignment between the cone and cup is essential to avoid premature wear. Lubrication must be the one recommended by the equipment manufacturer, and mounting requires specific tools to avoid damaging the raceways. If you have doubts, our technical team advises you.
Regarding equivalents, tapered roller bearings are identified by part numbers that vary between manufacturers. If you bring the part number from another brand, we can indicate the equivalent NTN reference. Interchangeability depends on dimensions and tolerances, so it is important to verify the complete designation. We work with the original nomenclature. If you need an alternative, send us the part number and we'll help you find it.
