When a shaft has to carry radial and axial loads at the same time, a double row tapered roller bearing keeps the assembly compact and rigid. NTN builds these units as a matched set of two roller rows in one mounting. MR Industrial Accessories supplies this line to maintenance and purchasing teams in the United States and Latin America.
The part number tells you what is inside the assembly. Take E-LM247748D/LM247710/LM247710DA: the E- prefix marks a special execution, LM247748D is the double row inner cone, LM247710 is the single outer ring, and LM247710DA is the double outer ring. The LM series and the D and DA suffixes identify the double row arrangement. E-LM772749D/LM772710/LM772710DA follows the same pattern.
You will find these bearings in gearboxes, machine tool spindles, overhead cranes, earthmoving equipment, support rollers and rotary tables, and in industries such as metallurgy, cement, mining and heavy machinery. The double row layout handles combined loads and tilting moments.
Selection comes down to the radial and axial capacity the application needs, the rotation speed and the working environment. Mounting calls for precise alignment and correct lubrication, with grease or oil depending on the case. Sealing matters as well: evaluate additional seals or a bearing with integrated seals where dust and particles are present.
Equivalent double row tapered roller bearings from other brands can be interchanged when the main dimensions and the row arrangement match. Check the complete part number and the tolerances, because small differences affect running. The MR team can advise on interchangeability and source the exact reference.

Frequently asked questions
- What does the designation E-LM247748D/LM247710/LM247710DA mean?
- It is a double row tapered roller assembly. The E prefix indicates a special execution; LM247748D is the double inner cone; LM247710 is the single outer ring; and LM247710DA is the double outer ring. Each component is identified separately.
- Can this bearing take axial loads in both directions?
- Yes. Its double row configuration supports axial loads in both directions together with radial loads, which suits applications with combined loads and tilting moments.
