- Tapered roller bearings, 323 series. For the same bore, each series has a different outside diameter and width.
- 17Bore
- 85 mm bore: 17 × 5.
- U2GDSuffix
- NTN suffix: it defines the variant (sealing, cage, internal clearance or other features).
32317 is the standard (ISO) basic designation: it defines the type, the series and the bore.

NTN tapered roller bearings are components designed to support combined radial and axial loads, with a high load capacity relative to their size. They are used in applications where motion must be transmitted with precision and rigidity, such as gearboxes, reducers, wheel axles and industrial equipment. At MR Accesorios Industriales we carry the NTN line with the technical assistance you need to choose the right part number for your application.
The designation of this series combines numbers and letters that identify the size and features of the bearing. For example, 32313U2GD, 32314U2GD, 32315U2GD, 32316U2GD and 32317U2GD share the same basic structure: the first digits indicate the dimension series, the letter U indicates an internal design feature, the 2 may refer to a tolerance or clearance suffix, and GD identifies the cage type or special treatment. Learn more about how to interpret these designations by checking the NTN catalog or writing to us.
These bearings are used in industries such as automotive, metalworking, mining and agriculture, in equipment such as transmission gearboxes, speed reducers, road machinery rollers, milling machine spindles and wheel axles. In Argentina, they are commonly found in agricultural machinery, earthmoving equipment and production lines. Their ability to support combined loads makes them ideal for assemblies where radial and axial forces occur simultaneously.
To select the right bearing, take into account the radial and axial load it must support, the rotation speed, the lubrication conditions and the type of sealing required. Mounting must ensure precise alignment and adequate internal clearance, since tapered rollers are sensitive to misalignment. Lubrication can be with grease or oil, depending on the application, and it is essential to maintain cleanliness during installation to avoid premature failures.
NTN tapered roller bearings are interchangeable with those of other brands that follow the same standardized dimensions, such as SKF, FAG, Timken or NSK. The key is to compare the main dimensions (bore, outer diameter and width) and the design type. If you have another brand's part number, we can help you find the right NTN equivalent. Always verify tolerances and axial clearance to ensure optimal operation.
If you need a quote for an NTN tapered roller bearing, write to us on WhatsApp with the part number or the dimensions you require.

Frequently Asked Questions
- What are the dimensions of the NTN 32317U2GD bearing?
- The NTN 32317U2GD bearing has a 85 mm bore, a 180 mm outside diameter and a 63.5 mm total width (85 x 180 x 63.5 mm). These are the standardised boundary dimensions (ISO 355) of the basic designation 32317.
- What does the U2GD suffix mean in NTN bearings?
- The U2GD suffix indicates specific internal design features, such as the cage type, heat treatment or tolerance. To interpret it accurately, check the NTN catalog or write to us with the full part number and we'll advise you.
- How do I know if an NTN tapered roller bearing is compatible with my equipment?
- Check the main dimensions (bore, outer diameter and width) and the design type. If you have the original part number, we can look for the NTN equivalent. Write to us on WhatsApp with the data and we'll help you confirm compatibility.
- What lubrication do you recommend for these bearings?
- Lubrication depends on the speed, load and working temperature. It can be with grease or oil. It is important to follow the equipment manufacturer's recommendations and maintain cleanliness. If you need advice, ask us.
