3. Structural Features

Component Composition: Composite structure (2 double-raceway inner rings, 1 double-raceway outer ring, 2 single-raceway outer rings) ensures stable force distribution.
Clearance Adjustment: Special inter-ring spacers for precise clearance adjustment, adapting to various working conditions.
Load-Bearing Advantage: Optimized structure enables concurrent large radial and specific axial load resistance, enhancing overall load efficiency.

4. Load-Carrying Capacity

Radial Load Capacity: ~2.5–3.5x radial load capacity of single-row tapered roller bearings; stable under high loads.
Load Type Adaptability: Excels at combined radial-axial loads (radial primary); withstands heavy/impact loads in harsh environments.

5. Performance Characteristics

Limiting Speed: Its limiting speed is a bit lower than four-row cylindrical roller bearings because of its structure, but it’s completely suitable for your heavy-load operating needs.
Axial Load Capacity: It can handle axial loads from both sides and works reliably as a bidirectional thrust bearing in your harsh industrial environment.

6. Material & Manufacturing

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

7. Application Fields

Primary Application: The proposed product is specifically engineered for the work rolls and backup rolls of rolling mills, which perfectly aligns with the project’s requirement to match European rolling mill equipment’s high-precision and heavy-load standards.
Other Applications: It is widely applicable to the project’s heavy-duty mechanical equipment (cranes, mining machinery, wind turbines), as these devices demand excellent resistance to high loads and impact loads.
