3. Structural Features
Component Composition: Constructed from dual tapered roller assemblies, double-groove inner ring, integral outer ring and high-precision rigid cage, the bearing features a compact, monolithic integrated structure.
Clearance Adjustment: An internal clearance adjustment mechanism is implemented to support fine-scale preload control and clearance trimming to satisfy practical operating parameters.
Load-Bearing Advantage: Such structural optimization elevates the overall stiffness significantly, enabling concurrent endurance of principal radial loads and bidirectional axial loads with well-distributed internal stress.
4. Load-Carrying Capacity
Radial Load Capacity: It comes with stronger radial bearing capability against single-row tapered roller bearings, catering to long-period heavy-duty operating needs.
Load Type Adaptability: Configured for mixed load environments where radial force is dominant and bidirectional axial force is supplementary, it endures continuous heavy loads, cyclic alternating loads and mechanical shock loads steadily.
5. Performance Characteristics
Limiting Speed: Adopting dedicated tapered roller contact design and appropriately calibrated friction pairs, this bearing maintains steady working performance during medium-low speed heavy-load operation, with quiet running and little friction power wastage.
Axial Load Capacity: Different from single-row tapered roller bearings that only resist single-direction axial loads, its symmetric double-row construction steadily withstands bidirectional axial thrust. It achieves precise axial positioning of shaft assemblies and offsets axial shift and operational mechanical vibration efficiently.
Operational Stability: Carefully distributed rollers and upgraded raceway contact greatly decrease running deflection and surface abrasion loss, supporting durable continuous stable service across various tough industrial working environments.
6. Material & Manufacturing
Inner and Outer Rings: Fabricated from high-purity bearing steel, they deliver exceptional hardness and outstanding structural stability to resist deformation.
Rolling Elements: Precisely machined tapered rollers boast uniformly distributed internal stress and excellent wear resistance.
Cage: The high-toughness rigid cage efficiently avoids roller offset and collision between rolling bodies.
Heat Treatment: Through integral quenching and tempering, the bearing gains enhanced surface hardness, superior fatigue resistance and extended service life, well suited for long-duration continuous industrial operation.
7. Application Fields
Primary Application: Primarily utilized for supporting roll necks, transmission structures and auxiliary bearing spots during the operation of steel rolling and metallurgical production machinery.
Other Applications: Capable of matching heavy industrial machinery requiring great rigidity and consistent bidirectional load performance, applicable to mining equipment, construction machinery, heavy-duty gear reducers and industrial power transmission assemblies.
