3. Structural Features

Component Composition: The experimental component is composed of two inner rings with double raceways, one outer ring with a double raceway, and two outer rings with single raceways.
Clearance Adjustment: To achieve precise clearance tuning, spacers are arranged between the inner and outer rings of the component.
Load-Bearing Advantage: Structural optimization is adopted to realize the simultaneous bearing of large radial loads and a certain degree of axial loads, improving the overall load capacity.

4. Load-Carrying Capacity

Radial Load Capacity: How strong is its radial load capacity? About 2.5–3.5 times stronger than single-row tapered roller bearings, so it’s reliable under high loads.
Load Type Adaptability: What loads can it handle? Combined radial-axial (radial main), plus heavy and impact loads in harsh working environments.

5. Performance Characteristics

Limiting Speed: Structural design results in a limiting speed somewhat lower than four-row cylindrical roller bearings, but it’s fully compatible with the heavy-load operating scenarios common in industrial settings.
Axial Load Capacity: Ideal for harsh industrial environments, it can bear axial loads from both sides and functions reliably 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: Rolling mill work rolls and backup rolls are its primary target, with a design that perfectly aligns with European rolling mills’ high-precision and heavy-load requirements.
Other Applications: In industrial settings requiring heavy-duty performance, it is widely used in cranes, mining machinery, wind turbines, and similar equipment needing excellent high-load and impact load resistance.
