3. Structural Features
Component Composition: It consists of two sets of tapered rolling bodies, double-row race inner ring, single-piece outer ring and high-rigidity precision cage, achieving compact structural arrangement and high integration degree.
Clearance Adjustment: Built-in adjustable internal clearance mechanism facilitates accurate preload and clearance adjustment to match different industrial operation environments.
Load-Bearing Advantage: Improved double-row symmetrical layout effectively strengthens overall rigidity, which bears substantial radial loads and bidirectional axial loads with uniformly balanced internal force.
4. Load-Carrying Capacity
Radial Load Capacity: Superior radial load carrying capability is achieved over single-row tapered roller bearings, satisfying the demands of prolonged heavy-load mechanical operation.
Load Type Adaptability: Perfectly constructed for composite loads where radial loads play the leading role and bidirectional axial loads act as complement, maintaining stable performance under continuous heavy loads, alternating dynamic loads and shock loads.
5. Performance Characteristics
Limiting Speed: Designed with industrial-grade tapered roller contact structure and perfectly matched friction pairs, the bearing runs smoothly under medium-low speed heavy-load working conditions of rolling mills, delivering quiet operation and low friction consumption.
Axial Load Capacity: Single-row bearings can only bear one-way axial force, while the double-row symmetric structure endures stable bidirectional axial thrust for metallurgical equipment. It achieves precise shaft axial positioning and eliminates axial shift and vibration during rolling production.
Operational Stability: Optimized roller layout and precise raceway fit reduce running deviation and wear, guaranteeing long-term stable continuous operation under high-temperature, heavy-load harsh metallurgical working environments.
6. Material & Manufacturing
Inner & Outer Rings: Made of high-purity bearing steel, they have high hardness and strong deformation resistance.
Rolling Elements: Accurately finished tapered rollers bear stress evenly and offer great abrasion resistance.
Cage: High-rigidity high-strength cage effectively prevents roller offset and impact friction.
Heat Treatment: Integral quenching and tempering improves surface hardness, fatigue durability and service life, meeting demands of long-term industrial operation.
7. Application Fields
Primary Application: These bearings serve as core supporting elements for roll necks, transmission fittings and auxiliary bearing locations equipped on steel rolling mills and metallurgical devices.
Other Applications: An excellent match for heavy-duty machinery pursuing high structural rigidity and stable dual-direction load capacity, applicable to mining equipment, engineering machinery, heavy gear boxes and complete industrial drive lines.
