3. Structural Features

Component Composition: The sophisticated composite raceway design with two double-raceway inner rings, one double-raceway outer ring and two single-raceway outer rings ensures reliable stability.
Clearance Adjustment: Built-in high-precision spacers allow flexible clearance adjustment between inner and outer rings, adapting to a variety of working conditions.
Load-Bearing Advantage: Through structural optimization, it achieves remarkable load-bearing performance and can carry heavy radial and certain axial loads at the same time.

4. Load-Carrying Capacity

Radial Load Capacity: The radial load capacity is 2.5–3.5 times that of single-row tapered roller bearings, guaranteeing unwavering reliability even under the most severe high-load scenarios.
Load Type Adaptability: It excels in supporting combined radial and axial loads with radial loads as the dominant part, and endures heavy loads and impact forces in tough operating environments.

5. Performance Characteristics

Limiting Speed: The presence of sliding contact between the rib and roller end face within the structural design raises friction levels during operation. For this reason, four-row tapered roller bearings have a relatively lower limiting speed than other bearings of equivalent size.
Axial Load Capacity: In contrast to single-row tapered roller bearings that resist only one-way axial loads, four-row tapered roller bearings are designed to endure heavy bidirectional axial loads. This performance ensures precise axial location and effective control of thrust generated during rolling. While providing excellent bidirectional thrust resistance, it mainly supports heavy radial loads, making it ideal for complex load conditions.
