3. Structural Features
Component Composition: It adopts two independent tapered roller assemblies, double-row inner race ring, integral outer ring and high-precision rigid retainer, featuring compact construction and high assembly compactness.
Clearance Adjustment: Internal clearance can be freely adjusted, which supports accurate preload control and reasonable clearance allocation based on real working situations.
Load-Bearing Advantage: Symmetrical double-row structure brings great improvement in overall rigidity, enabling simultaneous carrying of large radial and bidirectional axial loads with uniform internal stress dispersion.
4. Load-Carrying Capacity
Radial Load Capacity: Outperforming single-row tapered roller bearings in radial load capacity, it runs reliably under long-term heavy-load working conditions.
Load Type Adaptability: Perfectly compatible with combined loads led by radial loads and supported by bidirectional axial loads, it possesses excellent resistance to heavy loads, alternating dynamic loads and mechanical impact forces.
5. Performance Characteristics
Limiting Speed: Leveraging professional tapered roller contact construction and fine friction matching relation, this bearing delivers stable performance at medium and low speeds under heavy loads, with low running noise and tiny friction loss.
Axial Load Capacity: As opposed to single-row tapered roller bearings merely bearing single-direction axial loads, the symmetric double-row structure realizes stable bearing of bidirectional axial thrust, completes precise shaft axial positioning and offsets operational axial displacement and vibration efficiently.
Operational Stability: Advanced roller arrangement and superior raceway cooperation minimize running errors and surface wear, ensuring consistent long-term stable operation amid rigorous industrial working environments.
6. Material & Manufacturing
Inner & Outer Rings: Inner and outer rings are forged from high-purity bearing steel, presenting excellent hardness and strong ability to resist deformation.
Rolling Elements: Strictly processed tapered rollers make internal force distribution more reasonable and gain great wear resistance.
Cage: Scientific high-strength rigid cage design prevents roller shifting and collision during operation.
Heat Treatment: Entire bearing undergoes standardized quenching and tempering to strengthen surface hardness and fatigue performance, prolonging service life and complying with industrial application specifications.
7. Application Fields
Primary Application: Serving as core supporting components for roll neck, transmission assemblies and auxiliary bearing positions of various rolling mill and metallurgical mechanical systems.
Other Applications: An optimal choice for heavy machinery pursuing high rigidity and reliable two-way load bearing ability, widely used in mining, engineering machinery, heavy-duty gearboxes and complete industrial transmission lines.
