3. Structural Features
Component Composition: It is assembled from dual tapered roller units, double-row raceway inner ring, monolithic outer ring and high-precision rigid cage, boasting compact dimensions and high structural integration.
Clearance Adjustment: An internal adjustable clearance system is adopted, facilitating fine preload control and clearance setting based on real-world application needs.
Load-Bearing Advantage: This configuration markedly raises overall rigidity, capable of bearing primary radial loads and bidirectional axial loads concurrently while ensuring smooth, uniform internal force transfer.
4. Load-Carrying Capacity
Radial Load Capacity: Exhibiting excellent radial bearing capacity exceeding single-row tapered roller bearings, it fits long-cycle heavy-load industrial working conditions.
Load Type Adaptability: Optimized for compound load scenarios led by radial loads and assisted by bidirectional axial loads, it reliably copes with sustained heavy loads, cyclic alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Exclusive tapered roller contact construction and well-calibrated friction pairs deliver stable working performance for medium-low speed heavy-duty operation, alongside quiet running and limited friction power loss.
Axial Load Capacity: Separated from single-row bearings limited to single-way axial force bearing, the balanced double-row symmetric structure reliably endures bidirectional axial thrust. It achieves precise axial positioning of shaft assemblies and relieves axial displacement and equipment operational vibration efficiently.
Operational Stability: Scientifically optimized roller layout and seamless raceway matching greatly lower running offset and mechanical wear, adapting to all kinds of harsh industrial working scenes for sustained stable service.
6. Material & Manufacturing
Inner & Outer Rings: Premium high-purity bearing steel is adopted to manufacture ring assemblies, ensuring high hardness and stable load deformation resistance.
Rolling Elements: Delicately processed tapered rollers achieve balanced stress bearing and superior top-grade wear-proof performance.
Cage: Sturdy long-life high-rigidity cage efficiently restricts roller displacement and collision contact.
Heat Treatment: Monolithic quenching and tempering technology improves surface hardness and comprehensive fatigue resistance, extends service life and aligns with industrial long-cycle operation standards.
7. Application Fields
Primary Application: These bearings serve as core supporting parts at roll neck points, transmission support frameworks and auxiliary bearing seats of rolling mill and metallurgical production equipment.
Other Applications: A preferred choice for heavy industrial machinery pursuing superior rigidity and stable two-way load bearing performance, applicable to mining machinery, construction equipment, heavy-duty gear reducers and complete industrial drive parts.
