Decoding NTN 32314U2GD
- 323Series
- Tapered roller bearings, 323 series. Series differ in outside diameter and width even when the bore is the same.
- 14Bore
- Bore 70 mm (14 × 5).
- U2GDSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
32314 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 32314U2GD measures 70 mm across the bore and 150 mm across the outside diameter; its total width is 54 mm (70 x 150 x 54 mm).

NTN tapered roller bearings are built to carry both radial and axial forces at the same time, with a high capacity for their size. You will find them in gearboxes, reducers, wheel axles and other industrial equipment where motion needs to be precise and rigid. MR Industrial Accessories supplies the NTN line and can help you match the correct part number to your application.
The series covers part numbers such as 32313U2GD, 32314U2GD, 32315U2GD, 32316U2GD and 32317U2GD. Reading the code helps when you compare options: the leading digits give the dimension series, the U points to an internal design feature, the 2 can be a tolerance or clearance suffix, and GD relates to the cage type or a special treatment. The NTN catalog explains each element, or you can send us the full number and we will go over it with you.
These bearings appear in automotive, metalworking, mining and agricultural equipment. Typical examples include transmission gearboxes, speed reducers, road machinery rollers, milling machine spindles and wheel axles. Because they take radial and axial forces at the same time, they suit assemblies where both types of load occur together.
When choosing a bearing, look at the radial and axial load it will carry, the rotation speed, the lubrication conditions and the sealing you need. Mounting calls for precise alignment and the right internal clearance, as tapered rollers do not tolerate misalignment well. Grease or oil can be used depending on the application, and keeping the installation clean is essential to avoid early failures.
NTN tapered roller bearings can be swapped with other brands that use the same standardized dimensions, including SKF, FAG, Timken or NSK. Compare the bore, outer diameter and width, plus the design type. If you have another brand's part number, we can help you find the NTN equivalent. Always check tolerances and axial clearance to confirm proper operation.

Frequently asked questions
- NTN 32314U2GD bearing: what are its dimensions?
- NTN 32314U2GD measures 70 mm across the bore and 150 mm across the outside diameter; its total width is 54 mm (70 x 150 x 54 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 32314.
- What does the U2GD suffix mean in NTN bearings?
- The U2GD suffix covers internal design details such as cage type, heat treatment or tolerance. To interpret it for your part, check the NTN catalog or send us the full part number and we will advise you.
- How do I know if an NTN tapered roller bearing is compatible with my equipment?
- Compare the bore, outer diameter and width, and confirm the design type. If you have the original part number, we can look for the NTN equivalent. Send the data by WhatsApp or email and we will help you verify compatibility.
- What lubrication do you recommend for these bearings?
- The choice between grease and oil depends on speed, load and working temperature. Follow the equipment manufacturer's recommendations and keep the installation clean. If you need guidance, ask us.
