3. Structural Features
Component Composition: Equipped with twin tapered roller assemblies, double-row raceway inner ring, monolithic outer ring and rigid high-precision cage, it achieves compact size and superior structural integrity.
Clearance Adjustment: The built-in adjustable internal clearance structure allows users to precisely control preload and gap size matching various service scenarios.
Load-Bearing Advantage: Symmetrical double-row layout strengthens overall rigidity prominently, which withstands heavy radial loads and dual-direction axial loads with steady internal force dispersion.
4. Load-Carrying Capacity
Radial Load Capacity: Shows obvious advantages in radial load bearing compared with single-row structures, applicable to long-term stable heavy-load operation.
Load Type Adaptability: Adapted to compound load working modes with primary radial loads and secondary bidirectional axial loads. It maintains stable performance under heavy loads, varying alternating loads and impact loads.
5. Performance Characteristics
Limiting Speed: Reasonable tapered roller contact mode and matched friction design ensure stable operation of the bearing under medium-low speed heavy-duty conditions, along with low running noise and reduced friction loss.
Axial Load Capacity: Different from single-row products merely bearing one-way axial loads, this double-row symmetric structure bears reliable bidirectional axial thrust. It locks the shaft in accurate axial position and relieves axial displacement and vibration arising from equipment running.
Operational Stability: Well-designed roller arrangement and fine raceway matching cut down running deviation and wear significantly, supporting long-time uninterrupted stable operation in tough industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: Constructed with high-purity bearing steel, possessing great hardness and strong structural stability against deformation.
Rolling Elements: Finely machined tapered rollers feature evenly distributed internal stress and superior wear-proof performance.
Cage: High-toughness rigid cage effectively prevents roller running deviation and mutual striking.
Heat Treatment: Overall thermal quenching and tempering treatment improves surface hardness, fatigue resistance and working longevity, perfectly fitting long-term continuous industrial working demands.
7. Application Fields
Primary Application: Widely utilized at roll neck supports, transmission supports and auxiliary bearing positions for rolling mill and metallurgical industry equipment.
Other Applications: Fit for various heavy-duty mechanical units that require high structural rigidity and bidirectional load endurance, ranging from mining machinery, construction machinery to heavy gearboxes and industrial transmission equipment.
