The NTN double-row tapered roller bearing is a single assembly that houses two rows of tapered rollers. It handles radial and axial loads in both directions, making it a common choice where high load capacity and rigidity are needed, such as gearboxes, drive shafts and mining equipment. MR Industrial Accessories LLC supplies this line to customers across the United States and Latin America.
The part number tells you how the assembly is built. In E-M270749D/M270710/M270710DG2, the E-M prefix marks the double-row design, then come the cone and cup numbers. The D suffix shows a cone modification, while DG2 points to a cup variant. Other examples, such as E-M274149D/M274110/M274110DG2 and E-M284148D/M284111/M284210DG2, follow the same pattern: a separate code for the cone and for the cup, so each piece can be identified on its own.
These bearings appear in mining, cement, steel and oilseed operations, where equipment runs under heavy loads. They are found in speed reducers, mills, conveyor belts and construction machinery. Because they take combined loads, they suit drive shafts and support rollers in industrial plants.
When selecting a bearing, consider the radial and axial load, the rotation speed and the working environment. Mounting calls for precise alignment and proper lubrication, with grease or oil depending on the application. Sealing matters to keep out dust and particles, so evaluate additional seals. Set preload and internal clearance to the equipment specifications.
Double-row tapered roller bearings from other brands can be interchanged when the main dimensions and design match. Check the complete part number and tolerances. If you have a part number from another brand, we can identify a compatible alternative or quote the exact part you need.
To request a quote, send the part number from your equipment or the measurement you need by WhatsApp or email. We reply promptly and can also advise on mounting and lubrication.

Frequently asked questions
- What does the DG2 suffix mean in these bearings?
- DG2 indicates a variant in the cup design, which may involve changes to the profile or surface treatment. It is part of the NTN nomenclature and must be considered when replacing the bearing to ensure compatibility.
- Does this bearing come with seals or covers?
- Double-row tapered roller bearings are generally supplied without seals, since they are mounted inside a housing that contains the lubricant. For applications with contamination, evaluating the use of external seals is recommended.
- How do I request a quote for a specific part number?
- Send the complete part number shown on the bearing or in your equipment manual by WhatsApp or email. We will quote it promptly and suggest a compatible alternative if needed.
