3. Structural Features
Component Composition: This product adopts two groups of tapered rollers, double-row race inner ring, unified outer ring and high-precision reinforced cage, featuring compact overall design and reliable integrated structure.
Clearance Adjustment: It is fitted with adjustable internal clearance to achieve fine preload tuning and reasonable clearance control suitable for various working environments.
Load-Bearing Advantage: The balanced double-row symmetric structure upgrades integral bearing rigidity, allowing it to bear heavy radial force and bidirectional axial force simultaneously with well-distributed internal stress.
4. Load-Carrying Capacity
Radial Load Capacity: Superior radial load bearing efficiency is realized on this bearing over single-row types, enabling stable long-term heavy-load operation.
Load Type Adaptability: It is refined to suit operating conditions with major radial loads and subordinate bidirectional axial loads, delivering stable endurance to heavy loads, alternating loads and all kinds of mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Equipped with well-engineered tapered roller contact structure and optimized friction matching, the bearing operates smoothly under medium-low speed heavy-load conditions, featuring low noise output and minimal friction loss.
Axial Load Capacity: Unlike single-row bearings limited to unidirectional axial force bearing, the symmetrical double-row structure stably withstands bidirectional axial thrust. It delivers precise axial positioning for shaft assemblies and efficiently eliminates axial displacement and mechanical operating vibration.
Operational Stability: Refined roller layout and high-precision raceway fit greatly reduce operational deflection and abrasion, guaranteeing long-lasting stable continuous operation in harsh industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: Produced from premium high-purity bearing steel, these components own great hardness and strong structural stability against deformation.
Rolling Elements: Elaborately polished tapered rollers bear force evenly and possess exceptional abrasion-proof properties.
Cage: Adopting high-stiffness and high-toughness cage design, it efficiently avoids roller deflection and contact abrasion between rolling bodies.
Heat Treatment: Monolithic quenching and tempering process is utilized to enhance surface hardness, long-term fatigue performance and service lifespan, catering to prolonged industrial continuous operation.
7. Application Fields
Primary Application: Mainly used for roll neck support, transmission support and auxiliary bearing installation of steel rolling mills and metallurgical production equipment.
Other Applications: Suitable for heavy industrial machinery in need of high rigidity and bidirectional load resistance, including mining equipment, construction machinery, heavy-duty gearboxes and factory industrial transmission systems.
