3. Structural Features
Component Composition: Made up of two matched tapered roller units, double-row raceway inner ring, whole-type outer ring and high-precision firm cage, the product owns compact outline and high integration level.
Clearance Adjustment: The adjustable internal clearance layout ensures precise preload matching and clearance optimization for different industrial operating scenarios.
Load-Bearing Advantage: Symmetrical double-row framework greatly boosts structural stability and rigidity, supporting simultaneous heavy radial load and bidirectional axial load bearing with uniform internal stress transmission.
4. Load-Carrying Capacity
Radial Load Capacity: It has higher radial load bearing capacity than single-row tapered roller bearings, perfectly fitting long-term heavy-load operation in metallurgical industry.
Load Type Adaptability: Optimized for steel mill composite loads with radial loads as the main force and bidirectional axial loads as auxiliary force, it can steadily bear rolling heavy loads, alternating loads and equipment impact loads.
5. Performance Characteristics
Limiting Speed: With a well-engineered tapered roller contact structure and properly matched friction components, this bearing operates smoothly under medium-low speed heavy-load conditions, featuring quiet operation and minimal friction loss.
Axial Load Capacity: Unlike single-row bearings limited to unidirectional axial force bearing, its symmetrical double-row structure withstands stable bidirectional axial thrust. It delivers precise axial positioning for shaft assemblies and efficiently eliminates axial displacement and mechanical running vibration.
Operational Stability: Optimized roller layout and high-precision raceway fit greatly reduce operational deflection and wear, enabling long-lasting, steady continuous operation in harsh industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: High-purity bearing steel is adopted, offering high hardness and good deformation resistance.
Rolling Elements: Precisely made tapered rollers ensure uniform force and excellent wear resistance.
Cage: High-strength rigid cage effectively prevents roller deflection and collision.
Heat Treatment: Integral quenching and tempering improves surface hardness, fatigue resistance and service life, in line with long-term industrial use standards.
7. Application Fields
Primary Application: Widely fitted for roll neck supporting work, transmission supporting work and auxiliary bearing arrangement positions of metallurgical processing and steel rolling equipment.
Other Applications: Capable of meeting the usage needs of various heavy machinery with high rigidity and two-way load resistance, suitable for mining machinery, construction machinery, heavy gearboxes and industrial transmission operating systems.
