3. Structural Features
Component Composition: The bearing is assembled by two tapered roller sets, double-row race inner ring, solid one-piece outer ring and high-rigidity precision cage, owning compact structural arrangement and excellent integration performance.
Clearance Adjustment: Adjustable internal clearance mechanism supports high-precision preload and clearance regulation to match diverse industrial working environments.
Load-Bearing Advantage: Scientific double-row symmetric structural design effectively lifts integral stiffness, allowing the bearing to withstand big radial loads and bidirectional axial loads with evenly balanced internal force.
4. Load-Carrying Capacity
Radial Load Capacity: The radial load resistance is greatly enhanced in comparison to single-row tapered roller bearings, a great fit for prolonged heavy-duty mechanical running.
Load Type Adaptability: Its structural design caters to compound working loads led by radial loads and accompanied by bidirectional axial loads, reliably sustaining continuous heavy loads, alternating loads and mechanical shock loads throughout operation.
5. Performance Characteristics
Limiting Speed: A special tapered roller contact framework plus harmonized friction component matching ensures stable rotation under medium-low speed heavy loads, offering silent running performance and reduced friction power loss.
Axial Load Capacity: Where single-row tapered roller bearings are confined to unidirectional axial load bearing, the double-row symmetric structure provides stable resistance to bidirectional axial thrust. It completes precise axial positioning of shaft components and offsets axial displacement and operational vibration efficiently.
Operational Stability: Scientific roller arrangement and seamless raceway contact restrain running deflection and mechanical wear significantly, guaranteeing long-term steady continuous work under rigorous industrial conditions.
6. Material & Manufacturing
Inner & Outer Rings: Made of top-tier high-purity bearing steel, these ring components possess great hardness and stable anti-deformation capacity under heavy loads.
Rolling Elements: Precision-shaped tapered rollers bear stress evenly and maintain top-level wear-resistant properties during long-term operation.
Cage: Sturdy high-strength rigid cage effectively suppresses roller displacement and mutual collision contact.
Heat Treatment: The complete bearing is treated via monolithic quenching and tempering to lift surface hardness and general fatigue endurance, prolonging service life and satisfying long-cycle industrial operating norms.
7. Application Fields
Primary Application: This bearing series is widely applied to support roll necks, transmission assemblies and auxiliary bearing mounting positions of metallurgical and steel rolling machinery.
Other Applications: It fits all kinds of heavy-load mechanical devices with high stiffness and dual-direction load bearing requirements, covering mining equipment, construction machinery, heavy gear boxes and industrial drive systems.
