When a shaft has to carry radial and axial forces at the same time, in both directions, a double row tapered roller bearing from NTN is a common choice. These units are built for rigidity and load capacity in a small envelope, which suits gearboxes, transmission shafts and similar industrial machinery. MR Industrial Accessories LLC supplies this NTN line to customers throughout the United States and Latin America.
The part number itself tells you a lot. A prefix such as E- points to a special execution, and the following letters and digits—EE531201D and EE931170D are two examples—identify the cone type and the dimension series. A suffix like XDG2 covers internal details set by the manufacturer, including contact angle and surface treatment. Because those internal choices affect fit and performance, it pays to confirm the full code with our team before ordering.
You will find these bearings in demanding sectors: metallurgy, cement, mining and material processing. Speed reducers, mills, conveyor belts and construction machinery are typical hosts. Their ability to take combined loads keeps shafts aligned when stresses change direction or intensity.
Selection starts with the load: how large it is and which way it pushes. Rotation speed and the surrounding environment matter too. During mounting, alignment and lubrication have a direct effect on how long the bearing lasts. Check internal clearance and sealing for the site; dusty or humid conditions call for extra protection. Use the right tools so rollers and raceways are not damaged during installation.
If you are comparing an equivalent from another brand, look beyond the main dimensions. Load capacity and internal design can differ, and codes that appear similar may use different tolerances or materials. Give us the other brand's code and we can help you find the matching NTN reference. Always validate interchangeability technically before committing.

Frequently asked questions
- What does the XDG2 suffix indicate on these bearings?
- XDG2 is an internal designation from NTN that covers characteristics such as contact angle or raceway treatment. For the exact meaning on a specific reference, share the complete part number with us.
- How can I tell if this bearing fits my equipment?
- Check the mounting dimensions, the load capacity your application needs and the operating conditions. Send us the original part number or the housing dimensions and we will point you to the correct NTN reference.
- What lubrication should I use?
- It depends on speed, temperature and environment. High-viscosity greases are often used for heavy loads. Give us your application data and we will provide a specific recommendation.
