Double Row Tapered Roller Bearings

Double Rows Tapered Roller Bearings: Enhanced Stability for Heavy - Duty Equipment with High Radial Load Demands

Double Row Tapered Roller Bearings feature a compact integrated double-raceway design, providing significantly increased radial and bidirectional axial load capacity in a single unit without the need for paired mounting.

Available configurations include TDO (Double Outer Race) for easy installation and heavy industry applications, TDI (Double Inner Race) for high rigidity and load capacity, as well as paired mounting options such as DF (Face-to-Face) for bidirectional load handling and DB (Back-to-Back) for high overturning moment resistance.

Optimized roller profiles improve vibration resistance, reduce edge stress, and enhance anti-fatigue performance, making these bearings suitable for harsh operating conditions and continuous heavy-duty service.

Applications

  • Steel rolling mills and heavy industrial equipment
  • Mining crushers and vibrating screens
  • Heavy-duty gearboxes and transmission systems
  • Construction and material handling machinery
