3. Structural Features
Component Composition: This bearing integrates two sets of tapered rollers, double-row race inner ring, monolithic outer ring and high-stiffness precision cage, achieving compact structural layout and high assembly integration.
Clearance Adjustment: Featured with an adjustable internal clearance system, it delivers precise preload and clearance tuning for adaptation to all types of working environments.
Load-Bearing Advantage: Carefully refined double-row symmetrical structure elevates overall rigidity, enabling stable bearing of substantial radial loads and two-way axial loads with evenly spread internal force.
4. Load-Carrying Capacity
Radial Load Capacity: Superior radial load endurance is obtained versus single-row tapered roller bearings, catering to long-duration heavy-load operating requirements.
Load Type Adaptability: Purpose-designed for mixed working loads dominated by radial loads and paired with bidirectional axial loads, it resists sustained heavy loads, cyclic alternating loads and mechanical impact loads effectively.
5. Performance Characteristics
Limiting Speed: Adopting heavy-duty exclusive tapered roller contact structure and metallurgy-grade matched friction components, the bearing maintains stable rotation under medium-low speed heavy rolling mill loads, featuring low running noise and low friction power loss.
Axial Load Capacity: Different from single-row tapered roller bearings only capable of unidirectional axial load bearing, the robust symmetric double-row structure steadily bears bidirectional axial thrust for rolling mill shafts. It realizes precise axial positioning of rolling mill shaft systems and efficiently counteracts axial displacement and vibration during rolling production.
Operational Stability: Refined roller distribution and high-precision optimized raceway contact greatly reduce running deflection and abrasion under high-temperature heavy loads, adapting to harsh metallurgical workshop environments for long-term uninterrupted stable operation.
6. Material & Manufacturing
Inner & Outer Rings: Premium high-purity bearing steel provides high hardness and stable anti-deformation performance.
Rolling Elements: Precision-made tapered rollers bear stress evenly and offer top-tier wear resistance.
Cage: Durable high-strength rigid cage stops roller displacement and collision contact effectively.
Heat Treatment: Integral quenching and tempering boosts surface hardness and fatigue resistance, extends service life and meets long-cycle industrial usage standards.
7. Application Fields
Primary Application: Widely used to provide support for roll necks, transmission structures and auxiliary bearing mounting spots on rolling mill and metallurgical production machinery.
Other Applications: Ideal for all heavy-duty mechanical facilities demanding high structural stiffness and steady dual-direction load endurance, covering mining machines, engineering equipment, heavy gearboxes and industrial drive assemblies.
