3. Structural Features

Component Composition: The advanced multi-raceway composite structure including two double-raceway inner rings, one double-raceway outer ring and two single-raceway outer rings guarantees superior stability.
Clearance Adjustment: Precision spacers are arranged between inner and outer rings, realizing flexible clearance adjustment for diverse working requirements.
Load-Bearing Advantage: With optimized structure, it boasts extraordinary load capacity and can withstand high radial loads and certain axial loads concurrently.

4. Load-Carrying Capacity

Radial Load Capacity: It features 2.5–3.5 times the radial load capacity of single-row tapered roller bearings, ensuring reliable and uninterrupted performance under extreme heavy loads.
Load Type Adaptability: It shows excellent capability to handle combined radial and axial loads dominated by radial loads, and endures heavy loads and impact forces in harsh working scenarios.

5. Performance Characteristics

Limiting Speed: Sliding contact between the rib and the roller end face, a key structural attribute, leads to elevated friction during operation. Accordingly, the limiting speed of four-row tapered roller bearings is relatively lower than other same-size bearing types.
Axial Load Capacity: Unlike single-row tapered roller bearings that provide only unidirectional axial load resistance, four-row tapered roller bearings are engineered to deliver strong bidirectional axial load capacity. This ensures precise axial positioning and effective handling of thrust produced during rolling. While offering excellent bidirectional thrust performance, it primarily supports heavy radial loads.
