Four Row Tapered Roller Bearings represent the highest load capacity design in the tapered roller bearing family, engineered for extreme heavy-duty applications with severe shock loads, high temperatures, and continuous 24/7 operation.
The multi-row integrated structure distributes load across four rows of tapered rollers, significantly increasing radial and axial load capacity compared to single-row and double-row designs. Optional high-strength alloy steel and advanced heat-treated materials ensure stable performance under extreme industrial conditions.
Structural Features
- Four-row tapered roller configuration with integrated high-rigidity housing design
- Superior load distribution for extreme radial, axial, and impact loads
- High resistance to fatigue, misalignment, and vibration
- Optional high-temperature lubrication and reinforced sealing systems
- Large diameter and custom-size manufacturing capability
Applications
- Steel rolling mills (work rolls and backup rolls)
- Heavy-duty mining and crushing equipment
- Large-scale rotary kiln support systems
- Port cranes and heavy lifting equipment
- Extreme-load industrial transmission systems
