3. Structural Features
Component Composition: It consists of dual tapered roller units, double-path inner ring, unified integral outer ring and durable high-precision cage, achieving compact layout and perfect structural combination.
Clearance Adjustment: The independent adjustable internal clearance design ensures users can finely adjust preload and internal clearance in line with practical working environments.
Load-Bearing Advantage: Optimized symmetric double-row structure greatly strengthens integral stability, realizing simultaneous bearing of large radial and bidirectional axial loads with uniform force transmission inside.
4. Load-Carrying Capacity
Radial Load Capacity: Features stronger radial load bearing capacity than single-row tapered roller bearings, ideal for long-term heavy-load operation in metallurgical industry.
Load Type Adaptability: Perfectly fits steel mill composite loads with main radial loads and auxiliary bidirectional axial loads, steadily resisting heavy rolling loads, alternating loads and equipment impact loads.
5. Performance Characteristics
Limiting Speed: Thanks to the tapered roller contact design and scientifically matched friction structure, the bearing operates stably under medium and low speed heavy-load conditions with low running noise and low friction loss.
Axial Load Capacity: Different from single-row tapered roller bearings that only support one-way axial loads, its symmetrical double-row structure can steadily carry two-way axial thrust. It achieves accurate axial positioning of shaft parts and effectively offsets axial displacement and vibration generated during equipment operation.
Operational Stability: Optimized roller arrangement and precise raceway fit effectively reduce running deviation and wear, ensuring long-term continuous and stable operation in harsh industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: Premium bearing steel with high purity provides high hardness and strong structural anti-deformation capacity.
Rolling Elements: Meticulously machined tapered rollers ensure even stress distribution and excellent anti-wear property.
Cage: Sturdy rigid high-strength cage keeps rollers in place and avoids collision effectively.
Heat Treatment: The whole bearing is processed by quenching and tempering to strengthen surface hardness, fatigue resistance and working life, in line with industrial long-term service standards.
7. Application Fields
Primary Application: Mainly used for roll neck support, transmission support and auxiliary bearing parts of steel rolling mill and metallurgical equipment.
Other Applications: Applicable to heavy-duty machinery requiring high rigidity and bidirectional load resistance, including mining machinery, construction machinery, heavy gearboxes and industrial transmission systems.
