3. Structural Features
Component Composition: Consisting of two tapered roller groups, double-row raceway inner ring, unified outer ring and high-precision rigid retainer, it presents neat compact structure and high integration level.
Clearance Adjustment: It comes with adjustable inner clearance structure to achieve accurate preload configuration and clearance adaptation for actual working status.
Load-Bearing Advantage: Improved rigidity is achieved via double-row symmetric structure, so it can carry combined large radial loads and two-way axial loads with well-distributed internal forces.
4. Load-Carrying Capacity
Radial Load Capacity: Upgraded radial load bearing strength against single-row tapered roller bearings, fully fit for continuous heavy-load industrial operation.
Load Type Adaptability: Optimized structure fits composite loads focusing on radial force and complemented by double-direction axial force, resisting long-term heavy loads, alternating dynamic loads and mechanical collision loads effectively.
5. Performance Characteristics
Limiting Speed: Thanks to rational tapered roller contact structure and proper friction coordination, the bearing operates smoothly under medium and low speed heavy-load working modes, with low noise level and little friction loss.
Axial Load Capacity: Single-row tapered roller bearings only take unidirectional axial loads, whereas this double-row symmetric structure can bear stable two-way axial thrust. It completes precise axial positioning for shaft systems and effectively balances axial displacement and operational vibration.
Operational Stability: Optimized roller assembly layout and close raceway fit effectively restrain running offset and abrasion, securing long-term continuous stable operation amid complicated and harsh industrial conditions.
6. Material & Manufacturing
Inner & Outer Rings: High-purity bearing steel raw material grants high hardness and excellent deformation resisting ability.
Rolling Elements: High-precision processed tapered rollers ensure balanced stress bearing and outstanding abrasion-proof effect.
Cage: Reinforced high-strength rigid cage avoids roller deflection and collision efficiently.
Heat Treatment: Integrated quenching and tempering procedure enhances surface hardness, comprehensive fatigue resistance and service cycle, reaching industrial long-term use specifications.
7. Application Fields
Primary Application: Serving as core supporting bearings for roll neck, transmission components and auxiliary bearing areas of steel rolling mills and metallurgical plants.
Other Applications: Perfect match for heavy machinery featuring high rigidity demand and bidirectional load bearing needs, including mining facilities, road construction machinery, heavy-duty gearboxes and industrial transmission lines.
