When a shaft has to stay aligned while carrying radial and axial forces in both directions, a double row tapered roller bearing is often the right answer. NTN builds this assembly as one unit with two rows of tapered rollers. You will find it in gearboxes, final drives and mining equipment, where rigidity and load capacity matter. MR Industrial Accessories supplies the NTN line and can help you match the part number to your application.
Reading the code helps you order correctly. The prefix letter E marks a special design, M gives the dimension series, and a final D on the cone and cup shows the double row layout. Each complete bearing is made from a double cone plus two single cups. If you are unsure how the M series variants work, send us the designation and we will confirm what you need.
These bearings appear in speed reducers, overhead cranes, mills, crushers and railway equipment. Mining, cement, steel and earthmoving operations rely on them because the assembly keeps the shaft aligned under severe conditions. MR Industrial Accessories serves workshops and plants across the United States and in several Latin American countries.
Selection comes down to the radial and axial loads, the rotation speed and the environment. Proper alignment and correct lubrication are essential, whether grease or oil is used, and the sealing type usually decides which one applies. The E-M series normally includes seals that hold lubricant in and keep contaminants out. Check internal clearance and tighten components as specified to avoid early failures. Our team can walk you through the choice.
Interchange with other brands is possible when dimensions and load capacities line up. Do not compare only diameter and width; the contact angle and internal design also matter. If you have a part number from another maker, we can point you to the equivalent NTN reference. Always confirm interchangeability against the technical data for your specific application.

Frequently asked questions
- What does the E-M designation mean in NTN bearings?
- E stands for a special design and M identifies the dimension series. The D suffixes indicate the double row arrangement. A complete unit combines a double cone with two single cups.
- How do I choose the right double row tapered roller bearing?
- Look at radial and axial loads, speed, lubrication and sealing. Alignment and internal clearance are critical. Our technical team can advise you using the part number or the measurements of your application.
- Can I replace a bearing from another brand with an NTN one?
- Yes, if the dimensions, load capacity and contact angle match. Interchangeability must be verified with the specifications. Send us the original part number and we will indicate the equivalent NTN reference.
