NTN tapered roller bearings handle combined radial and axial loads in one direction. Their tapered raceways and rollers make linear contact, which spreads the load. You will find them in gearboxes, transmission shafts and industrial machinery where loads are heavy and misalignment is controlled. MR Industrial Accessories LLC supplies these bearings across the United States and Latin America, and can help you match the right reference to your equipment.
The NTN T series code breaks down into several parts. Take 4T-30313D7GB: the 4T prefix denotes a particular execution, 30313 is the size and type, D7 is an internal design variant, and GB covers tolerances and clearance. In 4T-30314D7GB, the series number changes and with it the dimensions. Reading these suffixes correctly is what lets you order a replacement that fits.
These bearings appear in food processing, cement, mining and automotive plants. They are common in speed reducers, road machinery shafts, conveyor belts and milling equipment, as well as machine tool spindles and support rollers. Because they take combined loads, they suit demanding environments where precision and durability matter to keep production running.
When selecting a tapered roller bearing, consider the radial and axial load, the rotation speed and the operating conditions. Mounting calls for careful alignment and correct axial clearance adjustment, usually with shims or nuts. Lubrication may be grease or oil depending on the application, and sealing is essential to keep lubricant in and contaminants out, so check the seal type your equipment requires.
Tapered roller bearings can be interchanged between brands when the main dimensions and raceway angle match, though tolerances and suffixes may differ from one maker to another. If you have a code from another brand or an unidentified part, MR Industrial Accessories LLC can identify the compatible equivalent. Always confirm the full number and specifications before replacing.
To request a quote, send the complete code or the measurements on WhatsApp or by email. The team replies promptly and can advise you so the part is the right one. If the designation is unclear, send a photo or the number marked on the bearing and we will help identify it.

Frequently asked questions
- What does the GB suffix mean in NTN bearings?
- GB indicates a tolerance and internal clearance variant under the standard. Respect it when replacing the bearing to keep the intended operation. If unsure, send us the complete code and we will advise you.
- How do I choose between a tapered roller bearing and a ball bearing?
- Tapered roller bearings support higher combined loads and suit shafts with significant loads. Ball bearings are for lower loads and higher speeds. The choice depends on the application; ask us and we will guide you.
- Can I replace a bearing from another brand with an NTN one?
- Yes, if the main dimensions and the raceway angle match. Tolerances and suffixes may vary between manufacturers. Bring us the original code or the measurements and we will tell you the appropriate NTN equivalent.
