Product Type: Double-Row Tapered Roller Bearing
1. Overview
Double-row tapered roller bearings are high-strength structural bearings optimized for heavy industrial operation. With high rigidity, stable rotation and strong combined load capacity, they can steadily operate under complicated load conditions, being vital supporting components for steel metallurgy, mining and heavy engineering machinery.

3. Structural Features
Component Composition: Constructed with two sets of tapered rollers, double-row raceway inner ring, integral outer ring and high-precision rigid cage, it has compact structure and high integration for heavy-duty use.
Clearance Adjustment: Adjustable internal clearance design ensures precise preload and clearance tuning to fit harsh on-site working conditions.
Load-Bearing Advantage: Double-row symmetric structure raises structural rigidity greatly, perfectly bearing large radial loads and bidirectional axial loads with uniform internal force distribution.
4. Load-Carrying Capacity
Radial Load Capacity: Achieves higher radial load endurance than single-row tapered roller bearings, reliable for long-period heavy-load service.
Load Type Adaptability: Perfectly matches combined load working conditions led by radial loads and supported by bidirectional axial loads, with excellent resistance to heavy loads, alternating loads and mechanical impact forces.
5. Performance Characteristics
Limiting Speed: Designed with standard tapered roller contact structure and scientific friction matching relation, it keeps stable running under medium-low speed heavy load, characterized by low operational noise and low friction energy loss.
Axial Load Capacity: Breaking the limit of single-row bearings that only bear one-way axial force, the double-row symmetric structure provides stable bidirectional axial bearing capacity. It ensures accurate shaft axial positioning and buffers axial displacement and vibration during mechanical operation.
Operational Stability: Rational roller arrangement and precise raceway matching greatly decrease running deflection and wear loss, making it suitable for long-term stable continuous work in all kinds of harsh industrial sites.
6. Material & Manufacturing
Inner & Outer Rings: Selected high-purity bearing steel offers high hardness and reliable anti-deformation performance.
Rolling Elements: Accurate manufacturing tapered rollers achieve uniform stress transmission and strong wear resistance.
Cage: Solid high-strength rigid cage effectively controls roller position and eliminates roller collision.
Heat Treatment: Through integral quenching and tempering treatment, surface hardness and overall fatigue resistance are greatly promoted, prolonging service life and meeting standard long-term industrial application needs.
7. Application Fields
Primary Application: Popularly installed on roll neck support, transmission support and auxiliary bearing positions of metallurgical and steel rolling processing equipment.
Other Applications: Adaptable to multiple heavy-load mechanical equipment with high rigidity and two-way load resistance requirements, such as mining machines, construction machinery, heavy transmission gearboxes and industrial drive systems.
