TIMKEN double row tapered roller bearings are self-contained assemblies that house two rows of tapered rollers in one mounting position. They handle radial and axial loads in both directions, making them a common choice where high load capacity and rigidity are required, such as gearboxes, drive shafts and mining equipment.
The part number starts with the NP prefix followed by six digits. Examples include NP025753, NP089744 and NP118297. The series designation — TDO, TDI, TNASW, 2TS-IM or 2TS-DM — points to a specific internal arrangement of cones, cups and seals, which affects how the bearing is mounted and how it performs.
These bearings appear in mining, cement, steel and power transmission operations. They are used in gear reducers, mills, conveyor belts and agricultural machinery. Their capacity for combined loads and moments suits shafts that demand high rigidity and precision.
Selection depends on the row arrangement, sealing type and internal clearance. Use the lubrication specified by the manufacturer, and pay close attention to shaft alignment to avoid extra stresses. During mounting, check the fit of cones and cups and follow the recommended tightening procedures. Some series, like TDO, may call for controlled preload.
When comparing with other brands, remember that codes can differ. Focus on the main dimensions, load capacity and configuration. Our team can help you identify a compatible alternative for your application.

Frequently asked questions
- What does the NP prefix mean in these bearings?
- The NP prefix identifies TIMKEN double row tapered roller bearings. The following digits are a unique reference number that may belong to different series, such as TDO or TDI, with variations in sealing and mounting.
- How do I choose between the TDO, TDI and TNASW series?
- The choice depends on the application: TDO is often used in preloaded configurations, while TDI and TNASW have specific mounting and sealing characteristics. For an accurate recommendation, contact us with your equipment details.
- Are they interchangeable with bearings from other brands?
- Equivalents may exist, but interchangeability depends on dimensions and capacities. Do not rely on the code alone. We can indicate a compatible alternative for your application.
