Product Type: Double-Row Tapered Roller Bearing
1. Overview
Double-row tapered roller bearings are high-strength structural bearings engineered for rigorous heavy-duty industrial environments. They possess outstanding rigidity, smooth rotational performance and remarkable integrated load capacity, readily adapting to multi-load complex working scenarios, and function as critical supporting elements for metallurgical, mining and heavy-duty machinery.

3. Structural Features
Component Composition: It includes two sets of tapered rollers, double-row raceway inner ring, integrated outer ring and high-precision rigid cage, featuring compact and highly integrated structure.
Clearance Adjustment: Adjustable internal clearance structure enables precise preload and clearance control based on diverse working needs.
Load-Bearing Advantage: Double-row symmetric design enhances overall rigidity, supporting simultaneous heavy radial and bidirectional axial loads with evenly spread internal forces.
4. Load-Carrying Capacity
Radial Load Capacity: Its radial load bearing performance is far better than single-row tapered roller bearings, suitable for long-time heavy-load mechanical operation.
Load Type Adaptability: Specially optimized for mixed load scenes prioritizing radial loads and supplemented by two-way axial loads, able to continuously bear heavy pressure loads, alternating fatigue loads and impact vibration loads.
5. Performance Characteristics
Limiting Speed: Featuring reliable tapered roller contact structure and optimized friction matching, the bearing maintains stable operation under medium and low speed heavy-load working conditions for metallurgical equipment, with low running noise and minimal friction loss.
Axial Load Capacity: Compared with single-row tapered roller bearings only bearing unidirectional axial loads, its double-row symmetric structure bears steady bidirectional axial thrust. It realizes accurate shaft axial positioning and offsets axial shift and vibration generated in rolling production.
Operational Stability: Upgraded roller layout and excellent raceway fitting reduce running deviation and wear effectively, ensuring long-term stable continuous operation under severe high-load industrial working environments.
6. Material & Manufacturing
Inner & Outer Rings: Adopt high-purity bearing steel with high surface hardness and excellent non-deformation property.
Rolling Elements: Precisely shaped tapered rollers own uniform stress structure and premium wear resistance.
Cage: Heavy-duty rigid cage effectively limits roller offset and prevents internal collision.
Heat Treatment: Standard overall quenching and tempering process optimizes surface hardness, fatigue resistance and service life, suitable for long-cycle industrial heavy-duty use.
7. Application Fields
Primary Application: Main usage covers roll neck support, transmission support and auxiliary bearing mounting areas in steel rolling mills and metallurgical mechanical systems.
Other Applications: Suitable for heavy industrial machinery that needs outstanding rigidity and reliable bidirectional load performance, including mining equipment, engineering construction machinery, heavy gear transmission boxes and industrial power transmission systems.
