3. Structural Features
Component Composition: Two sets of tapered rollers, double-row race inner ring, one-piece outer ring and high-stiffness precision cage form this bearing, presenting compact structural layout and superior integrated performance.
Clearance Adjustment: The adjustable internal clearance layout makes precise preload and clearance adjustment achievable for different on-site working environments.
Load-Bearing Advantage: Advanced optimized double-row symmetrical structure reinforces integral rigidity, supporting stable bearing of major radial loads and two-way axial loads with evenly allocated internal force.
4. Load-Carrying Capacity
Radial Load Capacity: Its ability to bear radial loads is greatly boosted relative to single-row tapered roller bearings, excellent for long-time heavy-duty continuous service.
Load Type Adaptability: Well adjusted for compound load operation with radial loads as the main bearing force and bidirectional axial loads as secondary force, it steadily resists persistent heavy loads, alternating loads and mechanical shock forces.
5. Performance Characteristics
Limiting Speed: Rationally configured tapered roller contact surfaces and calibrated friction pairing keep the bearing running smoothly under medium-low speed heavy-duty loads, with silent operation and restrained friction loss.
Axial Load Capacity: Single-row bearing models are only fit for one-way axial force, but the double-row symmetrical structure provides stable bearing capacity for bidirectional axial thrust. It completes precise axial positioning for shafts and suppresses axial shift and mechanical operation vibration effectively.
Operational Stability: Scientific roller distribution and high-precision raceway matching lower running deviation and wear extent, securing long-term stable continuous service under rigorous industrial working requirements.
6. Material & Manufacturing
Inner & Outer Rings: Utilizing high-purity bearing steel as core material, the rings possess high hardness and powerful deformation resistance under complex loads.
Rolling Elements: Accurate finishing on tapered rollers ensures balanced internal stress and superior abrasion-resistant property.
Cage: High-stiffness high-strength cage structure can efficiently eliminate roller offset and mutual impact friction during equipment running.
Heat Treatment: Integral thermal quenching and tempering upgrades surface hardness and fatigue durability, fully satisfying the long-cycle operation requirements of various industrial machinery.
7. Application Fields
Primary Application: Broadly adopted to undertake supporting work for roll necks, transmission parts and auxiliary bearing seats in metallurgical and steel rolling machinery.
Other Applications: Well-matched for heavy-load mechanical installations needing great stiffness and bidirectional load endurance, involving mining machines, engineering construction machinery, heavy-duty gear boxes and industrial transmission equipment.
