When a shaft has to handle radial and axial forces from both directions at once, a double row tapered roller bearing is often the answer. NTN builds this line as a matched assembly: two rows of tapered rollers sharing one axis. You will find these bearings in gearboxes, machine tool spindles and mining equipment, where rigidity and load capacity matter.
Reading the code helps you identify what you are looking at. The first letter E marks an NTN execution. Then L plus a number points to a cup and cone set. The letter D tells you the arrangement is double row, and DG signals a variant in cage or lubrication. Take the reference E-L281149D/L281110/L281110DG2: it brings together a main cone, a cup and a second cone with the DG2 suffix. Once you know the pattern, each designation becomes easier to interpret.
These bearings show up in tough spots: mill gearboxes, presses, cranes, earthmoving machines and milling spindles. Rolling mill rolls and food processing lines also use them. Because they take load in two directions, they suit assemblies where alignment is critical and the structure needs to stay rigid.
Selection starts with the radial and axial loads, the speed and the working environment. Sealing deserves attention: in dusty or damp conditions, integrated seals or external radial shaft seals are a good choice. Lubrication has to match the thermal regime. During mounting, align both rows precisely to avoid parasitic stresses. The right internal clearance spreads load evenly and helps the bearing last.
Double row tapered roller bearings follow international standards for dimensions and tolerances, so main sizes are interchangeable between brands even when codes differ. To confirm an equivalent, share the complete part number or the mounting dimensions. We can help you pin down the correct reference.

Frequently asked questions
- What does the DG suffix mean in the designation?
- In NTN bearings, DG usually points to a construction variant, such as a different cage design or a lubrication change. To be sure of its exact meaning, check with the manufacturer or send us the full part number on WhatsApp and we will help you.
- How do I choose between single row and double row?
- Go with double row when axial loads come from both directions and you need more rigidity. If the axial load acts in one direction only or speeds are very high, a single row may work. Always review the load and mounting conditions.
- What lubricant is recommended for these bearings?
- For high loads, a high-quality grease with EP additives is often used; oil fits centralized lubrication systems. Speed, temperature and environment drive the choice. Follow the equipment manufacturer's instructions and ask us if you are unsure.
