3. Structural Features
Component Composition: The bearing comprises dual tapered roller assemblies, a double-row raceway inner ring, an integrated outer ring and a high-precision rigid cage, delivering a compact, highly integrated overall layout.
Clearance Adjustment: Built with an internal adjustable clearance mechanism, it supports precise preload adjustment and clearance calibration to match on-site working conditions.
Load-Bearing Advantage: The optimized structure substantially enhances global stiffness, permitting simultaneous support of dominant radial loads plus bidirectional axial loads with uniform internal force transmission.
4. Load-Carrying Capacity
Radial Load Capacity: It provides greater radial load capacity than single-row tapered roller bearings to satisfy long-duration heavy-duty operation demands.
Load Type Adaptability: Crafted for mixed load conditions with dominant radial loads and supplementary bidirectional axial loads, it is capable of enduring persistent heavy loads, cyclic alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: With a one-of-a-kind tapered roller contact design and appropriately matched friction assemblies, the bearing operates steadily under medium-low speed heavy loads, creating low noise and minor friction power consumption.
Axial Load Capacity: Single-row tapered roller bearings are only fit for unidirectional axial loads, yet the symmetric double-row structure offers stable bidirectional axial thrust bearing capacity. It completes precise axial alignment of shaft systems and suppresses axial shift and mechanical running vibration thoroughly.
Operational Stability: Well-refined roller distribution and upgraded raceway contact minimize operational deflection and mechanical abrasion, supporting long-duration consistent stable operation in severe industrial working environments.
6. Material & Manufacturing
Inner & Outer Rings: High-purity premium bearing steel guarantees steady high hardness and stable anti-deformation performance under heavy-duty working loads.
Rolling Elements: Exactitude crafted tapered rollers deliver evenly spread internal stress and first-rate wear-resistant property.
Cage: Enduring high-strength rigid retainer effectively blocks roller dislocation and collision contact between rolling parts.
Heat Treatment: Integral thermal quenching and tempering process lifts surface hardness and whole-unit fatigue resistance, extends service lifespan and fits long-cycle industrial usage norms.
7. Application Fields
Primary Application: Mainly arranged at roll neck bearing supports, transmission load-bearing structures and auxiliary bearing positions equipped on steel rolling and metallurgical processing equipment.
Other Applications: Perfectly matched for heavy-load industrial machinery featuring high rigidity and consistent bidirectional load capacity, including mining devices, engineering construction machinery, heavy transmission reducers and industrial power transfer assemblies.
