3. Structural Features
Component Composition: Structured with dual tapered roller units, double-row race inner ring, seamless integral outer ring and high-rigidity precision cage, the bearing owns compact arrangement and high structural integration.
Clearance Adjustment: It comes with adjustable internal clearance construction, enabling precise preload and clearance fine-tuning to cope with diverse working conditions.
Load-Bearing Advantage: Polished double-row symmetric structure effectively upgrades overall stiffness, capable of carrying heavy radial loads and bidirectional axial loads with balanced internal stress distribution.
4. Load-Carrying Capacity
Radial Load Capacity: This bearing delivers significantly stronger radial load support than single-row tapered roller bearings, perfectly matching prolonged heavy-duty industrial running requirements.
Load Type Adaptability: Optimized layout adapts seamlessly to composite loads dominated by radial loads and supported by bidirectional axial loads, reliably enduring continuous heavy loads, alternating loads and all forms of mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Featuring a logically optimized tapered roller contact structure and balanced friction pairing, the bearing maintains smooth operational performance at medium and low heavy-load speeds, with quiet running and low friction consumption.
Axial Load Capacity: Different from single-row tapered roller bearings that merely carry one-way axial force, its double-row symmetric structure withstands consistent bidirectional axial thrust. It achieves precise shaft axial alignment and offsets axial displacement and equipment vibration during continuous operation.
Operational Stability: Refined roller placement and seamless raceway fit reduce operational deflection and abrasion levels, enabling durable stable continuous work under harsh heavy industrial conditions.
6. Material & Manufacturing
Inner & Outer Rings: Forged high-purity bearing steel endows inner and outer rings with high hardness and outstanding anti-distortion performance.
Rolling Elements: Precision finishing of tapered rollers delivers evenly balanced stress bearing and exceptional abrasion resistance.
Cage: Rigid high-strength retainer prevents roller shifting and reduces impact friction efficiently.
Heat Treatment: Full-component quenching and tempering technology is used to increase surface hardness, fatigue durability and service life, matching the operating needs of long-term industrial facilities.
7. Application Fields
Primary Application: Largely installed at roll neck supporting points, transmission supporting parts and auxiliary bearing mounting spots of various steel rolling mill and metallurgical machinery.
Other Applications: Perfect choice for all heavy-duty mechanical products with high stiffness and dual-direction load bearing demands, covering mining equipment, construction machinery, heavy gear boxes and industrial drive systems.
