3. Structural Features
Component Composition: Comprising two matched tapered roller groups, double-row raceway inner ring, monolithic outer ring and high-precision firm cage, it features neat structure and high assembly integration.
Clearance Adjustment: Featuring tunable internal clearance structure, it achieves accurate preload regulation and gap calibration to adapt to various heavy-duty working states.
Load-Bearing Advantage: Double-row symmetrical construction effectively improves overall bearing rigidity, permitting stable bearing of heavy radial loads and two-way axial loads with well-proportioned internal stress.
4. Load-Carrying Capacity
Radial Load Capacity: Better radial load capacity than single-row tapered roller bearings, ideal for long-term heavy load usage.
Load Type Adaptability: Suitable for combined loads of main radial force and secondary bidirectional axial force, enduring heavy loads, alternating loads and mechanical impact loads continuously.
5. Performance Characteristics
Limiting Speed: Adopting reasonable tapered roller contact structure and matched friction configuration, the bearing maintains smooth operation at medium and low speeds under heavy loads, presenting quiet operation and small friction consumption.
Axial Load Capacity: While single-row bearings can only bear unidirectional axial force, this double-row symmetrical structure is capable of bearing stable bidirectional axial thrust. It realizes accurate shaft axial positioning and efficiently eliminates axial shift and running vibration of mechanical equipment.
Operational Stability: Improved roller distribution and excellent raceway contact greatly lower operational deflection and abrasion, securing durable and uninterrupted stable operation in severe industrial working conditions.
6. Material & Manufacturing
Inner & Outer Rings: Manufactured from high-purity bearing steel, they possess high hardness and excellent resistance to deformation.
Rolling Elements: Precisely fabricated tapered rollers deliver uniform force distribution and exceptional wear resistance.
Cage: Built with high-strength rigid cage structure to effectively prevent roller offset and mutual collision.
Heat Treatment: The whole bearing is treated by integral quenching and tempering, which boosts surface hardness, overall fatigue resistance and service life, fully meeting long-term industrial application requirements.
7. Application Fields
Primary Application: It is widely deployed in roll neck support, transmission support and auxiliary bearing positions for rolling mill and metallurgical equipment.
Other Applications: This bearing is applicable to all heavy-duty mechanical equipment requiring high rigidity and bidirectional load resistance, such as mining machinery, construction machinery, heavy gearboxes and industrial transmission systems.
