3. Structural Features
Component Composition: Made up of two tapered roller groups, double-row raceway inner ring, one-piece formed outer ring and high-precision reinforced cage, the overall structure is compact and highly cohesive.
Clearance Adjustment: Its adjustable inner clearance layout enables accurate preload matching and clearance optimization according to different working requirements.
Load-Bearing Advantage: The symmetrical double-row framework significantly upgrades structural rigidity, allowing concurrent bearing of large radial loads and two-way axial loads with smooth and uniform internal force distribution.
4. Load-Carrying Capacity
Radial Load Capacity: This bearing boasts better radial load endurance than single-row counterparts, well qualified for prolonged heavy-duty running applications.
Load Type Adaptability: It is structurally optimized for composite loads where radial force acts as the main load and two-way axial force serves as auxiliary load, capable of enduring heavy loads, alternating loads and mechanical shock loads stably in long-term operation.
5. Performance Characteristics
Limiting Speed: The well-designed tapered roller contact structure and balanced friction matching enable stable operation in medium and low speed heavy-duty occasions, with low operational noise and reduced friction loss.
Axial Load Capacity: Distinguished from single-row products limited to one-way axial load bearing, this bearing adopts double-row symmetrical layout to bear steady bidirectional axial thrust. It locks the shaft in accurate axial position and buffers axial displacement and vibration arising from equipment running.
Operational Stability: Scientific roller arrangement and high-precision raceway matching cut down running deviation and wear significantly, supporting long-hour uninterrupted stable operation in tough industrial surroundings.
6. Material & Manufacturing
Inner & Outer Rings: Constructed with premium high-purity bearing steel, featuring reliable high hardness and powerful deformation resistance.
Rolling Elements: Finely finished tapered rollers ensure evenly spread force and superb wear-resistant performance.
Cage: Reinforced rigid cage with high strength effectively limits roller deviation and avoids contact collision.
Heat Treatment: Through overall thermal quenching and tempering, surface hardness and comprehensive fatigue resistance are improved, extending service life and satisfying long-cycle industrial operating standards.
7. Application Fields
Primary Application: Commonly installed to support roll necks, transmission components and auxiliary bearing parts of steel rolling mills and metallurgical plants.
Other Applications: Well-suited for all kinds of heavy-load mechanical facilities with high rigidity and dual-direction load resistance requirements, such as mining machinery, construction equipment, heavy-duty gear boxes and industrial drive assemblies.
