3. Structural Features
Component Composition: Equipped with dual tapered roller assemblies, double-row raceway inner ring, monolithic outer ring and high-rigidity precision cage, it achieves compact structure and outstanding assembly integration.
Clearance Adjustment: Featured with adjustable internal clearance mechanism, it supports precise preload control and clearance calibration adapting to practical operation requirements.
Load-Bearing Advantage: Optimized symmetric double-row design elevates overall rigidity significantly, which can withstand large radial loads and bidirectional axial loads concurrently with even internal stress dispersion.
4. Load-Carrying Capacity
Radial Load Capacity: It shows prominent advantages in radial load bearing performance against single-row tapered roller bearings, ideal for sustained heavy-duty operational work.
Load Type Adaptability: Highly flexible to cope with combined loads taking radial loads as main force and bidirectional axial loads as auxiliary force, with great stability to bear heavy loads, alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Optimized tapered roller contact structure and professional friction matching make the bearing run stably under medium and low speed heavy load in metallurgical industry, with low noise and small friction loss.
Axial Load Capacity: Different from single-row bearings only bearing single-side axial loads, its double-row symmetric structure bears stable two-way axial thrust, realizes precise shaft positioning and reduces axial displacement and vibration during rolling equipment operation.
Operational Stability: Reasonable roller arrangement and close raceway fit lower running deviation and wear, ensuring long-term stable continuous operation under high-load harsh working conditions of steel mills.
6. Material & Manufacturing
Inner & Outer Rings: Inner and outer rings adopt high-purity bearing steel, with remarkable hardness and excellent capability to resist pressure deformation.
Rolling Elements: Exquisitely crafted tapered rollers distribute operating force evenly and own superior wear-proof performance.
Cage: Solid integrated high-strength cage effectively avoids roller position deviation and internal collision friction.
Heat Treatment: Systematic integral quenching and tempering enhances surface hardness and overall fatigue strength, making it fully qualified for long-term continuous industrial application.
7. Application Fields
Primary Application: Primarily applicable to roll neck supporting points, transmission supporting positions and auxiliary bearing mounting spots of all types of rolling mills and metallurgical devices.
Other Applications: Suited for heavy-duty mechanical products featuring high structural strength and bidirectional load resistance, covering mining machinery, building machinery, heavy-load gearboxes and industrial transmission equipment.
