For equipment that has to handle radial and axial loads in both directions from a single mounting position, the NTN double row tapered roller bearing is an assembly that combines two rows of tapered rollers in one unit. It is used where high load capacity and rigidity are needed, such as gearboxes, transmission shafts and mining equipment.

The NTN designation for this series is built from three hyphen-separated blocks: T, E and a numeric group with a D suffix. Taking T-E-46791D/46720/46721D as an example, the first block (46791D) is the inner cone, the second (46720) is the cup, and the third (46721D) is the opposite cone. The trailing D marks a design modification, usually tied to geometry or surface treatment. Reading the code this way lets you identify each component when you need a replacement or want to ask about a specific piece.

Typical service locations include mining equipment, cement plants, crushing plants, mills, conveyor belts and agricultural machinery. The arrangement supports combined loads and moments, which makes it a fit for speed reducers, roller shafts and power transmission systems working around dust, vibration and changing temperatures.

When selecting, review the radial and axial load, the rotation speed, the lubrication method and the sealing required. Mounting calls for precise alignment and a correct fit between cone and cup. Grease or oil can be used depending on the operating regime. Check internal clearance and mounting tolerances to help avoid premature failure.

Equivalent bearings from other brands may exist, but dimensions and tolerances need to be verified before any replacement. Interchangeability depends on each manufacturer's technical specifications. If you have a code from another brand, the team can help you find the matching NTN reference.
