3. Structural Features

Component Composition: Comprises two double-raceway inner rings, one double-raceway outer ring, and two single-raceway outer rings.
Clearance Adjustment: Spacers are installed between the inner and outer rings to enable precise clearance adjustment.
Load-Bearing Advantage: The structure is optimized to withstand significant radial loads and certain axial loads simultaneously.

4. Load-Carrying Capacity

Radial Load Capacity: Boasting a radial load capacity approximately 2.5-3.5 times that of single-row tapered roller bearings, it complies with the high-precision load specifications in industrial applications.
Load Type Adaptability: Engineered specifically for combined radial and axial loads (taking radial loads as the main part), it demonstrates superior resistance to heavy and impact loads.

5. Performance Characteristics

Limiting Speed: A relatively lower limiting speed, compared to four-row cylindrical roller bearings, is a result of structural constraints and is accepted in exchange for higher load-carrying capacity.
Axial Load Capacity: Axial load capacity is provided in both directions, allowing for deployment as a bidirectional thrust bearing to fulfill requirements for two-way axial loading.

7. Application Fields

Primary Application: It addresses the specific needs of rolling mill work rolls and backup rolls, delivering a perfect solution for the high-precision and heavy-load challenges in European rolling mill equipment.
Other Applications: This product also effectively serves other heavy-duty applications like cranes, mining machinery, and wind turbines, where it is tasked with managing significant static and dynamic loads.
