Product Type: Double-Row Tapered Roller Bearing
1. Overview
Double-row tapered roller bearings belong to high-strength bearing products oriented at heavy-duty industrial scenarios. With stable running performance, superior rigidity and powerful comprehensive load-bearing strength, they adapt efficiently to complex combined load working modes and support the normal operation of metallurgical, mining and multiple heavy mechanical facilities.

3. Structural Features
Component Composition: Fitted with two tapered roller groups, double-row raceway inner ring, solid integrated outer ring and high-precision rigid cage, it has compact structure and superior structural integration property.
Clearance Adjustment: Its internal clearance can be adjusted freely, realizing precise preload positioning and clearance setting conforming to actual working conditions.
Load-Bearing Advantage: The rational symmetric double-row structure greatly increases overall bearing rigidity, realizing simultaneous bearing capacity for heavy radial loads and bidirectional axial loads with evenly distributed internal pressure.
4. Load-Carrying Capacity
Radial Load Capacity: Enhanced radial load performance makes it more reliable than single-row tapered roller bearings for long-term heavy-duty running.
Load Type Adaptability: Specially optimized for dual combined loads of main radial force and auxiliary bidirectional axial force, it maintains stable working status under heavy loads, alternating loads and mechanical collision loads.
5. Performance Characteristics
Limiting Speed: Thanks to a logically structured tapered roller contact design and properly matched friction components, the bearing maintains smooth performance under medium-low speed heavy-duty working modes, with silent operation and low friction wastage.
Axial Load Capacity: Distinct from single-row models that only endure single-direction axial force, its symmetric double-row layout holds steady bidirectional axial thrust. It completes accurate axial positioning of shaft systems and removes axial displacement and equipment running vibration efficiently.
Operational Stability: Upgraded roller arrangement and precise raceway matching minimize operational offset and wear loss, securing sustained stable continuous operation under tough industrial working conditions.
6. Material & Manufacturing
Inner & Outer Rings: Inner and outer rings are made of refined high-purity bearing steel, with prominent hardness and robust ability to resist distortion.
Rolling Elements: Finely manufactured tapered rollers deliver evenly dispersed internal stress and superior anti-wear effect.
Cage: High-strength rigid cage restricts abnormal roller movement and reduces collision friction between tapered rollers.
Heat Treatment: Standard full-piece quenching and tempering technology upgrades surface hardness, fatigue endurance and overall service cycle, satisfying long-duration industrial operation standards.
7. Application Fields
Primary Application: This bearing is largely applied in roll neck support, transmission support and auxiliary bearing fixing positions for rolling mill and metallurgical industrial machinery.
Other Applications: It can be used on different heavy-duty machines which demand high rigidity and stable bidirectional load performance, such as mining tools, engineering devices, heavy gearboxes and industrial transmission assemblies.
