Product Type: Double-Row Tapered Roller Bearing
1. Overview
Double-row tapered roller bearings are high-strength bearings optimized for heavy-load metallurgical industrial scenarios. Featuring high rigidity, smooth operation and strong overall load capacity, they adapt to complex combined load working conditions and are core supporting components for steel rolling, mining and large heavy-duty mechanical equipment.

3. Structural Features
Component Composition: Constructed by two sets of tapered rollers, double-row raceway inner ring, integral outer ring and high-precision stable cage, it features compact overall construction and excellent comprehensive integration performance.
Clearance Adjustment: Professional adjustable internal clearance structure ensures high-precision preload and clearance adjustment for different practical working situations.
Load-Bearing Advantage: Advanced double-row symmetric structure enhances whole-body rigidity remarkably, enabling stable simultaneous bearing of heavy radial loads and bidirectional axial loads with uniform internal stress distribution.
4. Load-Carrying Capacity
Radial Load Capacity: It boasts significantly higher radial load bearing capacity compared with single-row tapered roller bearings, making it perfect for long-term heavy-duty service scenarios.
Load Type Adaptability: Optimized for compound load operating conditions with radial loads as the primary stress and bidirectional axial loads as secondary stress. It reliably withstands continuous heavy loads, cyclic alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Scientific collocation of tapered roller contact structure and friction pairs ensures smooth operation for the bearing in medium-low speed heavy-load states, characterized by low running noise and little friction consumption.
Axial Load Capacity: Where single-row bearings can only bear unidirectional axial thrust, the double-row symmetrical structure supports stable bidirectional axial loads. It achieves precise axial positioning for shafts and mitigates axial shift and mechanical operational vibration effectively.
Operational Stability: Advanced roller layout design and accurate raceway cooperation restrain running deflection and abrasion, enabling durable steady continuous service in complicated severe industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: Premium high-purity bearing steel is selected for ring production, characterized by high hardness and excellent deformation resisting performance.
Rolling Elements: High-precision finished tapered rollers achieve uniform stress bearing and outstanding abrasion resistance.
Cage: Reinforced rigid cage with great strength and stiffness can effectively block roller offset and impact wear.
Heat Treatment: We adopt integral quenching and tempering craftsmanship to raise surface hardness, fatigue durability and service life, which perfectly matches the needs of long-period industrial equipment operation.
7. Application Fields
Primary Application: Focusing on metallurgy and steel rolling industry, it is extensively used for roll neck support, transmission support and auxiliary bearing installation work.
Other Applications: It matches the application demands of high-rigidity heavy machinery with bidirectional load resistance, covering mining facilities, construction machinery, heavy transmission boxes and industrial power delivery systems.
