3. Structural Features
Component Composition: Comprising two groups of tapered rollers, double-row raceway inner ring, integral outer ring and high-precision rigid cage, it delivers compact structure and excellent overall integration effect.
Clearance Adjustment: Adjustable inner clearance construction enables accurate preload adjustment and clearance control to satisfy actual industrial operating demands.
Load-Bearing Advantage: Double-row symmetrical structural design effectively raises overall rigidity, which can bear heavy radial loads and bidirectional axial loads together with uniform internal stress distribution.
4. Load-Carrying Capacity
Radial Load Capacity: It can bear larger radial loads than single-row tapered roller bearings, which satisfies the working needs of long-term heavy-load continuous running.
Load Type Adaptability: Matched with compound load environments where radial loads prevail and bidirectional axial loads assist, it operates steadily while undertaking heavy loads, alternating loads and external mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Reasonably designed tapered roller contact geometry and balanced friction pairing enable consistent smooth running at medium and low speeds under heavy loads, offering quiet operation and reduced friction energy consumption.
Axial Load Capacity: Single-row tapered roller bearings merely support one-way axial loads, whereas this double-row symmetric construction bears stable two-way axial thrust. It realizes precise axial fixation of shafts and effectively suppresses axial shift and vibration generated during machine operation.
Operational Stability: Optimized roller distribution and seamless raceway coordination cut down running deviation and wear significantly, supporting reliable long-term continuous service amid rigorous industrial working scenarios.
6. Material & Manufacturing
Inner & Outer Rings: High-purity bearing steel serves as raw material for inner and outer rings, granting them high hardness and reliable deformation resistance.
Rolling Elements: Accurately processed tapered rollers ensure balanced stress bearing and long-lasting resistance to abrasion.
Cage: The high-rigidity high-strength cage structure limits roller shifting and eliminates impact friction efficiently.
Heat Treatment: Integral thermal treatment combining quenching and tempering elevates surface hardness and fatigue durability, extending service life to fit long-term industrial working scenarios.
7. Application Fields
Primary Application: It is widely used for roll neck, transmission and auxiliary bearing supporting positions of rolling mills and metallurgical machinery.
Other Applications: It is suitable for heavy machinery requiring high rigidity and bidirectional load resistance, including mining machinery, engineering machinery, heavy gearboxes and industrial transmission systems.
