3. Structural Features
Component Composition: Structured with two sets of tapered rolling elements, double-row race inner ring, integrated outer ring and high-stability rigid cage, it owns compact volume and high structural integrity.
Clearance Adjustment: Designed with flexible internal clearance mechanism, it facilitates precise preload control and clearance adjustment catering to actual on-site service conditions.
Load-Bearing Advantage: Adopting balanced double-row symmetric structure, it gains superior overall rigidity, able to withstand combined heavy radial loads and bidirectional axial loads with evenly allocated internal forces.
4. Load-Carrying Capacity
Radial Load Capacity: It achieves superior radial load bearing capability compared with single-row tapered roller bearings, which makes it ideal for long-term heavy-load operational use.
Load Type Adaptability: Optimized to fit combined load environments dominated by radial loads and supplemented by bidirectional axial loads. It can steadily withstand heavy loads, alternating loads and mechanical impact loads for sustained continuous work.
5. Performance Characteristics
Limiting Speed: With rational tapered roller contact mode and optimized friction pairing, it keeps stable working performance under medium-low speed heavy-load scenarios, featuring low noise emission and minimal friction power loss.
Axial Load Capacity: Breaking the limitation of single-row tapered roller bearings with only unidirectional axial bearing capacity, the symmetric double-row structure endures reliable bidirectional axial thrust. It ensures precise shaft system positioning and relieves axial displacement and operational vibration effectively.
Operational Stability: Refined roller assembly design and close raceway cooperation effectively restrain running deviation and excessive wear, adapting to complex harsh industrial sites for long-term steady service.
6. Material & Manufacturing
Inner & Outer Rings: Adopting high-purity bearing steel material, these parts come with great hardness and stable anti-deformation capability.
Rolling Elements: Accurately machined tapered rollers realize balanced stress bearing and prominent anti-wear property.
Cage: High-rigidity and high-strength cage can efficiently stop roller displacement and internal collision.
Heat Treatment: Integral quenching and tempering process is applied to upgrade surface hardness, fatigue durability and working longevity, conforming to standard long-term industrial usage norms.
7. Application Fields
Primary Application: Widely utilized for roll neck support, transmission support and auxiliary bearing installation positions on rolling mills and metallurgical equipment.
Other Applications: Perfect for various heavy-duty machinery that requires high rigidity and bidirectional load bearing capacity, including mining devices, engineering machinery, heavy gearboxes and industrial transmission systems.
