3. Structural Features
Component Composition: It is assembled with two groups of tapered rollers, double-row raceway inner ring, integral outer ring and high-precision rigid cage, with compact structure and high integration for heavy industrial use.
Clearance Adjustment: The adjustable internal clearance structure supports accurate preload and clearance adjustment to adapt to harsh heavy-load operating conditions.
Load-Bearing Advantage: Symmetrical double-row structure greatly enhances overall rigidity, suitable for bearing heavy radial loads and bidirectional axial loads synchronously with evenly distributed internal stress.
4. Load-Carrying Capacity
Radial Load Capacity: Its radial load resistance is vastly improved relative to single-row tapered roller bearings, well suited for extended heavy-load industrial operation.
Load Type Adaptability: The structural design caters to mixed load environments dominated by radial forces and supplemented by two-way axial forces, delivering stable endurance against persistent heavy loads, alternating dynamic loads and mechanical shock forces.
5. Performance Characteristics
Limiting Speed: Utilizing rationally constructed tapered roller contact surfaces and well-matched friction pairs, the bearing runs smoothly under medium-low speed heavy-load working status, boasting quiet operation and low friction power loss.
Axial Load Capacity: Single-row tapered roller bearings are restricted to one-way axial force bearing, yet the symmetric double-row structure delivers reliable endurance against two-way axial thrust. It locks shaft assemblies in precise axial positions and offsets axial displacement and machine vibration during operation.
Operational Stability: Enhanced roller placement and tight raceway fit reduce running deviation and wear levels effectively, meeting the demand for long-term stable continuous operation under harsh industrial circumstances.
6. Material & Manufacturing
Inner & Outer Rings: Fabricated using high-purity bearing steel, the rings come with elevated hardness and powerful protection against deformation under heavy loads.
Rolling Elements: Precisely shaped tapered rollers balance internal stress effectively and maintain excellent resistance to surface abrasion.
Cage: High-rigidity heavy-duty cage structure avoids roller dislocation and mutual impact friction during running.
Heat Treatment: The integral quenching and tempering procedure improves surface hardness and anti-fatigue property, prolonging service life for uninterrupted long-term industrial service.
7. Application Fields
Primary Application: Widely deployed as supporting bearings for roll necks, transmission assemblies and auxiliary bearing seats of steel rolling mills and metallurgical machinery.
Other Applications: Perfectly fit all heavy-duty mechanical units requiring high rigidity and bidirectional load capacity, including mining equipment, construction machinery, heavy-duty gearboxes and industrial drive systems.
