Double row tapered roller bearings handle radial and axial loads in both directions, making them a practical choice for gear reducers, final drives, and heavy equipment. MR Industrial Accessories LLC supplies NTN double row tapered roller bearings to customers across the United States, Canada, Mexico, and South America. Send your part number via WhatsApp or email, and our team will quote it or help you find an equivalent.
NTN designations for these bearings follow a structured format. For example, in E-M278749D/M278710/M278710DAG2, the segments separated by slashes identify the cone, the cup, and the complete assembly. The prefix E- indicates a special execution, while the suffix D denotes a double row design. Checking the exact code on your equipment helps ensure you receive the correct part.
These bearings are suited for applications where high rigidity and alignment are critical, such as mining, cement, steel, and earthmoving operations. Typical installations include speed reducers, gearboxes, support rollers, overhead cranes, and railway equipment. Their ability to manage combined loads and moments makes them a dependable option for demanding assemblies.
When selecting a bearing, consider the radial and axial loads, operating speed, and environmental conditions. Proper installation requires precise alignment and verification of internal clearance. Use the appropriate lubricant based on temperature and contamination levels, and follow the manufacturer's relubrication schedule. In dusty or humid environments, choose configurations with radial shaft seals. Assembly with a hydraulic press and proper calibration helps prevent damage to raceways.
Double row tapered roller bearings from different manufacturers may be interchangeable if key dimensions and load capacities match, but tolerances and suffixes can vary. If you have a code from another brand or an unidentified part, contact us via WhatsApp or email. We can suggest a compatible alternative or quote the NTN code you need.

Frequently asked questions
- What does the suffix D mean in an NTN bearing designation?
- In NTN nomenclature, the suffix D typically indicates a double row design. In a code like E-M278749D/M278710/M278710DAG2, the D appears in both the cone and cup segments, confirming that the assembly has two rows of tapered rollers.
- How can I verify if this bearing replaces the one I currently have?
- Compare the main dimensions—bore, outer diameter, and width—along with the load capacity. If you have the original part number, send it to us via WhatsApp or email, and we will identify the equivalent in the NTN line.
- What type of lubricant works best for these bearings?
- The best lubricant depends on speed, temperature, and operating environment. For general use, a high-viscosity lithium grease is often suitable. Under severe conditions, contact our technical team for a specific recommendation.
