3. Structural Features
Component Composition: It is configured with two groups of tapered rollers, double-path inner ring, seamless integral outer ring and high-precision rigid retainer, with neat overall structure and excellent combined performance.
Clearance Adjustment: Reasonable adjustable inner clearance structure facilitates accurate preload setting and flexible clearance adjustment based on real working status.
Load-Bearing Advantage: Scientific double-row symmetric layout strengthens overall structural rigidity, realizing synchronous bearing of heavy radial and bidirectional axial loads with evenly spread internal stress.
4. Load-Carrying Capacity
Radial Load Capacity: It owns stronger radial load bearing property than single-row tapered roller bearings, ensuring stable running throughout long-term heavy-load service.
Load Type Adaptability: Well-adjusted for mixed load working modes dominated by radial loads and equipped with bidirectional axial loads, it maintains continuous stable performance under heavy loads, alternating loads and shock loads.
5. Performance Characteristics
Limiting Speed: Optimized tapered roller contact and friction structure ensure stable operation at medium and low heavy-load speeds with low noise and low friction loss.
Axial Load Capacity: It supports stable bidirectional axial thrust unlike single-row tapered roller bearings, achieves precise shaft axial positioning and reduces operational axial displacement and vibration.
Operational Stability: Optimized roller and raceway structure reduces running deviation and wear, ensuring long-term stable operation in harsh industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: Produced from high-purity bearing steel, featuring high surface hardness and strong deformation resistance for heavy load work.
Rolling Elements: High-precision machined tapered rollers ensure uniform force bearing and strong wear resistance under harsh working conditions.
Cage: High-strength rigid cage effectively prevents roller offset and collision in high-load operation.
Heat Treatment: Overall quenching and tempering treatment improves surface hardness and fatigue resistance, prolongs service life and meets long-term service demands of metallurgical and heavy industry equipment.
7. Application Fields
Primary Application: Widely fitted for roll neck supporting work, transmission supporting work and auxiliary bearing arrangement positions of metallurgical processing and steel rolling equipment.
Other Applications: Capable of meeting the usage needs of various heavy machinery with high rigidity and two-way load resistance, suitable for mining machinery, construction machinery, heavy gearboxes and industrial transmission operating systems.
