3. Structural Features
Component Composition: Assembled from two groups of tapered rollers, double-row track inner ring, seamless integral outer ring and high-rigidity precision cage, the structure is concise and highly unified.
Clearance Adjustment: It adopts flexible internal clearance construction, making it easy to realize precise preload control and clearance modification according to actual operation demands.
Load-Bearing Advantage: Rational double-row symmetric layout reinforces overall structural rigidity, which can bear big radial force and bidirectional axial force synchronously with balanced internal stress distribution.
4. Load-Carrying Capacity
Radial Load Capacity: Outperforms single-row tapered roller bearings in radial load capacity, ensuring stable operation under long-term heavy-load working status.
Load Type Adaptability: Highly adaptable to combined loads with radial loads as main force and bidirectional axial loads as auxiliary force, featuring great endurance to heavy loads, variable alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Properly arranged tapered roller contact structure and reasonable friction collocation enable stable operation under medium-low speed heavy loads, achieving quiet operation and low friction loss.
Axial Load Capacity: Beyond the unidirectional axial load limit of single-row tapered roller bearings, this symmetric double-row structure undertakes stable two-way axial thrust, realizes precise shaft axial positioning and weakens operational axial displacement and vibration.
Operational Stability: Perfect roller arrangement and high-precision raceway cooperation effectively avoid running deviation and excessive wear, supporting long-duration stable continuous operation in harsh industrial surroundings.
6. Material & Manufacturing
Inner & Outer Rings: Composed of high-purity bearing steel, characterized by high hardness and superb deformation resistance.
Rolling Elements: High-precision tapered rollers realize uniform stress bearing and exceptional wear resistance.
Cage: High-strength rigid retainer effectively avoids roller deviation and internal collision friction.
Heat Treatment: Integrated thermal treatment including quenching and tempering improves surface hardness, integral fatigue performance and service life, adapting to long-cycle industrial working environment.
7. Application Fields
Primary Application: Primarily applied in roll neck supporting positions, transmission supporting parts and auxiliary bearing locations within steel rolling and metallurgical industry.
Other Applications: Compatible with all kinds of heavy-load mechanical equipment pursuing high rigidity and dual-direction load stability, including mining machinery, building machinery, heavy-duty gearboxes and industrial transmission facilities.
