3. Structural Features
Component Composition: Comprising two sets of tapered rollers, double-row race inner ring, one-piece molded outer ring and high-rigidity precision cage, it has compact layout and high-level structural integration.
Clearance Adjustment: Featuring adjustable internal clearance, the bearing supports precise preload and clearance optimization to adapt to all kinds of industrial working environments.
Load-Bearing Advantage: The refined double-row symmetric layout strengthens overall rigidity, with the capacity to bear substantial radial loads and bidirectional axial loads under evenly distributed internal force.
4. Load-Carrying Capacity
Radial Load Capacity: The radial load limit is greatly elevated when compared with single-row tapered roller bearings, ideal equipment for extended heavy-load production operations.
Load Type Adaptability: Scientifically designed for combined load scenarios with dominant radial loads and auxiliary bidirectional axial loads, it performs reliably under lasting heavy loads, cyclic alternating loads and mechanical impact pressure.
5. Performance Characteristics
Limiting Speed: The bearing adopts a mature tapered roller contact design and reasonably matched friction pairs to operate smoothly under medium-low speed heavy loads, running with little noise and low friction loss.
Axial Load Capacity: Single-row tapered roller bearings can only resist one-way axial loads, whereas the double-row symmetrical structure bears reliable bidirectional axial thrust. It realizes precise axial positioning for shaft systems and effectively mitigates axial displacement and vibration during machine operation.
Operational Stability: Enhanced roller arrangement and accurate raceway cooperation minimize running deflection and abrasion, delivering durable stable continuous performance amid complex harsh industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: Constructed from top-grade high-purity bearing steel, they deliver high hardness and reliable resistance to structural deformation.
Rolling Elements: Exquisitely machined tapered rollers achieve evenly distributed stress and exceptional wear resistance.
Cage: Robust high-tensile rigid cage efficiently limits roller shifting and prevents roller-to-roller collision.
Heat Treatment: The entire bearing undergoes integral quenching and tempering to raise surface hardness and overall fatigue resistance while prolonging service life, fully complying with standards for long-cycle industrial operation.
7. Application Fields
Primary Application: Mainly used for supporting roll necks, transmission parts and auxiliary bearing positions of rolling mill equipment and metallurgical production machinery.
Other Applications: Ideal for heavy industrial equipment in steel, mining and construction sectors that requires high rigidity and bidirectional load bearing capacity, including mining machinery, engineering equipment, heavy-duty gearboxes and factory industrial drive systems.
