The NTN double row tapered roller bearing consists of two rows of tapered rollers arranged on a shared axis. This configuration handles radial and axial loads in both directions, making it suitable for gearboxes, final drives and mining equipment. The design also permits fine adjustment of internal clearance and provides long service life in tough conditions.
Part numbers in this series follow a pattern. For example, E-LM272249D/LM272210/LM272210DG2 and E-LM283649D/LM283610/LM283610DG2. The E- prefix denotes a special execution. The base code gives the main dimensions. A D suffix on the cone points to an internal design change, while DG2 on the cup indicates a lubrication or sealing variant. Each assembly typically includes two cones and two cups, and in some cases an extra cup for double row arrangements.
These bearings appear in mining, cement, steel and heavy machinery manufacturing. Typical equipment includes speed reducers, mills, crushers, cranes and earthmoving machines. Their capacity for combined loads and their rigidity suit shafts that demand high precision and resistance to fatigue.
When selecting, consider the radial and axial loads, the rotational speed and the operating environment. Installation calls for careful alignment and correct setting of internal clearance, which is done by moving the cups axially. Use a lubricant that matches the temperature and speed, and ensure sealing keeps contaminants out. Follow the manufacturer's instructions for each application.
Interchange between brands is possible if the main dimensions and internal design are the same. Always check tolerances and axial clearance for compatibility. For a replacement, compare the full codes and technical data. If you are unsure, send us the original part number and we will advise you.

Frequently asked questions
- What does the E- prefix indicate in the part number?
- The E- prefix stands for a special execution, which may involve changes in internal design, tolerances or surface treatments. It is part of the NTN code and must be kept when ordering a replacement.
- How is internal clearance set on this bearing?
- Internal clearance is set by moving the cups axially during assembly. Follow the manufacturer's recommended procedure to avoid too much preload or clearance, which can affect service life.
- Can I use a bearing from another brand as a replacement?
- Yes, if the main dimensions and internal design match. Check tolerances and axial clearance. Send the original part number and we will identify a compatible equivalent.
