3. Structural Features
Component Composition: Assembled from two groups of tapered rolling bodies, double-row race inner ring, integrated outer ring and high-precision sturdy cage, it features compact layout and high structural integration.
Clearance Adjustment: Built-in adjustable inner clearance design allows users to precisely adjust preload and clearance to match diverse on-site working conditions.
Load-Bearing Advantage: Double-row symmetrical construction greatly improves integral stiffness, capable of undertaking heavy radial loads and two-way axial loads at the same time with balanced internal force distribution.
4. Load-Carrying Capacity
Radial Load Capacity: Effectively raises the limit of radial load bearing compared with single-row structures, adapting seamlessly to long-term high-load steady running.
Load Type Adaptability: Engineered for comprehensive composite loads mainly bearing radial loads with auxiliary bidirectional axial loads, it keeps stable performance under heavy loads, frequent alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Scientific combination of tapered roller contact structure and friction matching enables steady operation under medium-low speed heavy loads, characterized by low operating noise and economical friction loss.
Axial Load Capacity: The unique double-row symmetric structure enables it to bear bidirectional axial thrust steadily, overcoming the defect that single-row tapered roller bearings can only bear one-way axial loads. It ensures accurate axial positioning and effectively suppresses axial displacement and working vibration.
Operational Stability: Optimized internal roller layout and excellent raceway fitting greatly restrain running deviation and component wear, guaranteeing continuous stable operation for a long time in complex industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: High-quality high-purity bearing steel guarantees high hardness level and reliable deformation resistance of ring parts.
Rolling Elements: Professionally processed tapered rollers enable uniform force bearing and maintain excellent wear resistance for long time.
Cage: Rigid high-strength cage effectively restricts irregular movement and collision of tapered rollers.
Heat Treatment: Adopting whole-piece quenching and tempering technology, it elevates surface hardness and fatigue resistance, extends service cycle and reaches industrial long-term use standards.
7. Application Fields
Primary Application: Frequently deployed to bear loads for roll necks, transmission units and auxiliary bearing structures equipped on rolling mill and metallurgical operational machinery.
Other Applications: Ideal selection for heavy industrial equipment with high rigidity standard and bidirectional load bearing needs, applicable to mining industry, construction machinery, heavy gearboxes and industrial transmission overall systems.
