3. Structural Features
Component Composition: Made up of dual tapered roller units, double-row raceway inner ring, integrated outer ring and high-precision rigid cage, its whole construction is compact and highly integrated.
Clearance Adjustment: Adopting adjustable clearance mechanism inside, it supports fine preload regulation and clearance calibration according to practical working requirements.
Load-Bearing Advantage: Such structural design significantly improves overall stiffness, enabling simultaneous bearing of major radial and bidirectional axial loads with uniform internal force delivery.
4. Load-Carrying Capacity
Radial Load Capacity: Possesses superior radial bearing capability over single-row tapered roller bearings, meeting the demands of long-duration heavy-load operation.
Load Type Adaptability: Tailored for mixed load environments dominated by radial loads and matched with bidirectional axial loads, capable of enduring persistent heavy loads, cyclic alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: With exclusive tapered roller contact construction and properly matched friction components, it maintains stable working performance at medium and low speeds under heavy loads, delivering low noise output and small friction power loss.
Axial Load Capacity: Distinct from single-row tapered roller bearings limited to unidirectional axial load bearing, the symmetric double-row structure supports stable bidirectional axial thrust bearing. It realizes accurate shaft system axial positioning and offsets axial displacement and running vibration efficiently.
Operational Stability: Refined roller distribution and optimized raceway contact greatly reduce operational deviation and mechanical wear, adapting to harsh industrial scenes for long-term steady continuous operation.
6. Material & Manufacturing
Inner & Outer Rings: Premium high-purity bearing steel material ensures high hardness and stable anti-deformation capability.
Rolling Elements: Precision crafted tapered rollers realize uniform stress bearing and top-grade wear-resistant property.
Cage: Durable high-strength rigid cage effectively restricts roller displacement and collision contact.
Heat Treatment: Adopt monolithic quenching and tempering process to boost surface hardness, overall fatigue resistance and extend service life, conforming to long-cycle industrial usage norms.
7. Application Fields
Primary Application: Mainly deployed in roll neck supporting points, transmission supporting structures and auxiliary bearing locations of steel rolling and metallurgical production equipment.
Other Applications: Applicable to heavy industrial machinery needing excellent rigidity and stable bidirectional load capacity, including mining machinery, engineering machinery, heavy gear reducers and industrial power transmission assemblies.
