3. Structural Features

Component Composition:Consists of two double-raceway inner rings, one double-raceway outer ring, and two single-raceway outer rings.
Clearance Adjustment:Equipped with spacers between inner and outer rings for precise clearance adjustment.
Load-BearingAdvantage:Structurally optimized to bear large radial loads and certain axial loads simultaneously.

---

4. Load-Carrying Capacity

Radial Load Capacity: Approximately 2.5-3.5 times that of single-row tapered roller bearings.
Load Type Adaptability: Suitable for combined radial and axial loads (with radial loads as the main component), and capable of withstanding heavy loads and impact loads.

---

5. Performance Characteristics

Limiting Speed: Relatively lower than four-row cylindrical roller bearings due to structural constraints.
Axial Load Capacity: Can withstand axial loads in both directions, and can be used as a bidirectional thrust bearing.

6. Material & Manufacturing

Heat Treatment: Special heat treatment process applied to enhance hardness, wear resistance, and fatigue life.

7. Application Fields

Primary Application:Work rolls and backup rolls of rolling mills.
Other Applications:Heavy-duty mechanical equipment such as cranes, mining machinery, and wind turbines (requiring high load and impact load resistance).
