3. Structural Features
Component Composition: Equipped with two groups of tapered rollers, double-row race inner ring, integral single-piece outer ring and high-stiffness precision cage, it achieves compact layout and high structural integrity.
Clearance Adjustment: The internal clearance can be freely adjusted, which enables precise preload and clearance setting to fit different equipment working environments.
Load-Bearing Advantage: Upgraded double-row symmetrical layout reinforces overall rigidity, undertaking massive radial loads and two-way axial loads with well-distributed internal force.
4. Load-Carrying Capacity
Radial Load Capacity: This bearing’s radial load capacity sees a substantial rise over single-row tapered roller bearings, making it the optimal pick for long-running heavy-duty industrial applications.
Load Type Adaptability: Tailored for environments with combined radial and bidirectional axial loads (radial loads primary), it reliably carries persistent heavy loads, alternating fatigue loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Featuring exclusive tapered roller contact construction and properly calibrated friction assemblies, the bearing maintains consistent working performance at medium and low heavy-load speeds, with low noise generation and minor friction energy loss.
Axial Load Capacity: Separated from single-row models that only withstand one-way axial force, its symmetric double-row structure steadily bears bidirectional axial thrust. It realizes accurate axial fixation of shaft systems and suppresses axial shift and machine running vibration thoroughly.
Operational Stability: Improved roller distribution and optimized raceway matching greatly decrease operational offset and surface wear, perfectly fitting harsh industrial environments for prolonged stable continuous operation.
6. Material & Manufacturing
Inner & Outer Rings: Premium high-purity bearing steel material delivers stable high hardness and reliable structural anti-deformation capability.
Rolling Elements: Elaborately manufactured tapered rollers achieve uniform stress distribution and premium wear-resistant attributes.
Cage: Wear-resistant high-rigidity cage efficiently limits roller dislocation and collision contact between tapered rollers.
Heat Treatment: Integral quenching and tempering technology is utilized to strengthen surface hardness and overall fatigue resistance, extending service cycles and complying with industrial long-service standards.
7. Application Fields
Primary Application: Regularly deployed to provide reliable support for roll necks, transmission parts and auxiliary bearing spots equipped on rolling mill and metallurgical mechanical facilities.
Other Applications: Perfectly suited to heavy-duty mechanical machinery demanding high rigidity and two-way load endurance, including mining machines, construction equipment, heavy transmission gearboxes and industrial drive equipment.
