3. Structural Features
Component Composition: Consisting of two groups of tapered rolling elements, double-row race inner ring, one-piece integrated outer ring and high-rigidity precision cage, the bearing boasts compact layout and high structural integration performance.
Clearance Adjustment: Built-in adjustable internal clearance allows precise preload matching and clearance calibration to adapt to multiple mechanical service environments.
Load-Bearing Advantage: Advanced symmetric double-row design effectively strengthens overall bearing stiffness, reliably undertaking large radial loads and bidirectional axial loads with balanced internal force delivery.
4. Load-Carrying Capacity
Radial Load Capacity: Its radial load capacity outperforms single-row tapered roller bearings, fulfilling the needs of long-period heavy-load industrial operation.
Load Type Adaptability: Customized for composite working loads where radial force takes precedence and bidirectional axial force serves as auxiliary, it can bear persistent heavy loads, cyclic alternating loads and mechanical impact loads reliably.
5. Performance Characteristics
Limiting Speed: Built with exclusive tapered roller contact construction and perfectly matched friction components, the bearing sustains reliable working performance at medium and low heavy-load speeds, outputting low noise and small friction power waste.
Axial Load Capacity: Distinguished from single-row bearings that merely support single-direction axial force, its symmetric double-row layout steadily withstands bidirectional axial thrust. It enables accurate axial alignment of shaft systems and eliminates axial shift and operational mechanical vibration effectively.
Operational Stability: Delicately arranged rollers and refined raceway contact greatly cut down running deflection and mechanical wear loss, suitable for long-cycle steady continuous operation in complex industrial harsh environments.
6. Material & Manufacturing
Inner & Outer Rings: The inner and outer rings utilize premium high-purity bearing steel to secure high hardness and stable resistance to deformation under complex loads.
Rolling Elements: Precision engineered tapered rollers achieve evenly balanced stress bearing and superior top-tier abrasion resistance.
Cage: Tough durable high-rigidity cage structure efficiently controls roller offset and collision contact.
Heat Treatment: Integral quenching and tempering procedures enhance surface hardness and whole-component fatigue resistance, extending service cycles and meeting long-term industrial production norms.
7. Application Fields
Primary Application: Mainly tasked with supporting roll necks, transmission parts and auxiliary bearing seats for all types of steel rolling equipment and metallurgical machinery.
Other Applications: Well adapted to heavy-duty mechanical facilities with strict high-stiffness and bidirectional load bearing standards, including mining machines, engineering equipment, heavy gear boxes and industrial power transmission systems.
