3. Structural Features
Component Composition: Assembled with dual tapered roller units, double-row inner ring, integrated outer ring and high-precision rigid cage for compact, highly integrated construction.
Clearance Adjustment: Internal adjustable clearance supports fine preload tuning and clearance calibration as required by field operation.
Load-Bearing Advantage: The structure lifts overall stiffness, taking primary radial and bidirectional axial loads simultaneously with evenly transferred internal forces.
4. Load-Carrying Capacity
Radial Load Capacity: It has superior radial load capacity compared with single-row tapered roller bearings, meeting requirements of long-duration heavy-load operation.
Load Type Adaptability: Tailored for mixed load environments dominated by radial loads and paired with bidirectional axial loads, it can endure persistent heavy loads, cyclic alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Built around exclusive tapered roller contact geometry and properly matched friction parts, the bearing retains reliable working status under medium-low speed heavy-duty working conditions, generating low noise and minimal friction power consumption.
Axial Load Capacity: Single-row tapered roller bearings can only bear one-way axial force; the symmetric double-row structure breaks this limit and stably endures bidirectional axial thrust. It completes precise axial alignment of shaft assemblies and mitigates axial shift and equipment vibration effectively.
Operational Stability: Upgraded roller distribution and refined raceway coordination greatly cut operational offset and mechanical abrasion, adapting to severe industrial working environments for prolonged steady continuous running.
6. Material & Manufacturing
Inner & Outer Rings: Top-quality pure bearing steel forms the inner and outer rings, delivering high hardness and steady resistance to mechanical deformation.
Rolling Elements: High-precision fabricated tapered rollers achieve balanced internal stress and premium anti-wear attributes.
Cage: Tough long-lasting high-rigidity cage structure restricts roller offset and collision contact efficiently.
Heat Treatment: Integral quenching paired with tempering enhances surface hardness and whole-component fatigue durability, lengthens service lifespan and conforms to long-cycle industrial operation norms.
7. Application Fields
Primary Application: Largely installed on roll neck supporting seats, transmission bearing structures and auxiliary bearing locations of all types of steel rolling mill and metallurgical production equipment.
Other Applications: Qualified for various heavy-load mechanical devices that need prominent rigidity and steady bidirectional load endurance, involving mining machines, engineering construction machinery, heavy gearboxes and industrial power transmission equipment.
