3. Structural Features

Component Composition: An innovative composite raceway design — consisting of two double-raceway inner rings, one double-raceway outer ring, and two single-raceway outer rings — ensures superior operational stability.
Clearance Adjustment: Precision spacers placed between inner and outer rings give flexible clearance adjustment, making the bearing suitable for diverse operating scenarios.
Load-Bearing Advantage: Structural optimization grants outstanding load capacity, easily supporting heavy radial loads together with some axial loads simultaneously.

4. Load-Carrying Capacity

Radial Load Capacity: The radial load capacity is enhanced to 2.5–3.5 times that of single-row tapered roller bearings, delivering reliable performance even under extreme high-load conditions.
Load Type Adaptability: It adapts perfectly to combined radial and axial loads (mainly radial loads) and withstands heavy loads and impact forces in harsh industrial environments.

5. Performance Characteristics

Limiting Speed: The structural configuration featuring sliding contact between the rib and roller end face results in elevated friction during operation. Thus, the limiting speed of four-row tapered roller bearings is relatively lower than other similar-sized bearings.
Axial Load Capacity: In contrast to single-row tapered roller bearings with only one-way axial load capability, four-row tapered roller bearings are optimized to support heavy bidirectional axial loads. This performance guarantees accurate shaft positioning and efficient control of thrust produced during rolling. While excelling in bidirectional thrust resistance, it mainly carries heavy radial loads.
