How to read NTN 32018XU
- 320Series
- Tapered roller bearings, 320 series. For the same bore, each series has a different outside diameter and width.
- 18Bore
- 90 mm bore: 18 × 5.
- XUSuffix
- NTN suffix: it defines the variant (sealing, cage, internal clearance or other features).
32018 is the standard (ISO) basic designation: it defines the type, the series and the bore.

NTN XU series tapered roller bearings are components designed to support combined radial and axial loads. Their cone and cup geometry allows linear contact that distributes loads better, ideal for applications with moderate to high demands. They are used in industrial machinery, transmission equipment and systems where precision and rigidity are important. MR Accesorios Industriales sells this series.
The XU series designation is interpreted from the base number and the suffix. For example, in 31320XU, the initial digits indicate the size and the dimensional series, while the XU ending identifies characteristics specific to NTN manufacturing. Other examples such as 32019XU or 31330XU follow the same logic: the numeric code defines dimensions and load capacity, and the XU suffix groups variants with specific attributes. To select the right bearing, it is essential to identify the complete code and consult the dimension and capacity tables.
These bearings are used in a wide variety of industries in Argentina. They are found in gear reducer boxes, gear transmission systems, mining equipment, road machinery, flour mills and cement plants. They are also present in the agro-industrial sector, in seeders and harvesters, and in railway applications. Their ability to support combined loads makes them suitable for wheel axles, spindles and transmission shafts where high rigidity and rotational precision are required.
For a correct selection, take into account the magnitude and direction of the loads, the operating speed and the environmental conditions. Mounting tapered rollers requires precise alignment and proper adjustment of the axial clearance, which is usually regulated by nuts, lock nuts or shims. Lubrication must be chosen according to temperature and speed: grease for slow applications or oil for high revolutions. Sealing is critical to prevent contamination by dust or particles, thus extending the bearing's service life.
Regarding equivalents and interchangeability, tapered roller bearings are manufactured under international standards that allow replacements between different brands, provided the main dimensions and load capacities match. When looking for a replacement, it is important to verify the complete code and the tolerances. MR Accesorios Industriales can advise you to find the right option according to the original part code or the measurements taken.

Frequently Asked Questions
- What are the dimensions of the NTN 32018XU bearing?
- The NTN 32018XU bearing has a 90 mm bore, a 140 mm outside diameter and a 32 mm total width (90 x 140 x 32 mm). These are the standardised boundary dimensions (ISO 355) of the basic designation 32018.
- What does the XU suffix mean on NTN bearings?
- The XU suffix identifies specific NTN manufacturing characteristics within the tapered roller series. To interpret it correctly, it is necessary to consult the complete code and the manufacturer's technical tables. Write to us via WhatsApp and we will help you identify the exact reference.
- How do I choose the right tapered roller bearing for my application?
- To select the right bearing, consider the radial and axial loads, the rotation speed, the temperature and the working environment. The type of mounting and the lubrication are also important. With that data, we can advise you and quote the NTN reference that best suits your equipment.
- Are NTN XU series bearings interchangeable with other brands?
- Yes, tapered roller bearings follow international dimension standards, so they can be interchanged between brands if the measurements and capacities match. Always verify the complete code and the tolerances. If you send us the original part code, we will indicate the compatible equivalent.
