Product Type: Double-Row Tapered Roller Bearing
1. Overview
Double-row tapered roller bearings are sturdy structural bearings built for heavy industry. High rigidity, stable rotation and strong overall load bearing enable them to fit complex combined load environments perfectly, widely used as key support parts for metallurgical, mining and heavy mechanical devices.

3. Structural Features
Component Composition: This bearing is fitted with double sets of tapered rollers, double-row race inner ring, all-in-one outer ring and high-standard rigid cage, featuring compact outline and high integration degree.
Clearance Adjustment: Equipped with adjustable inner gap structure, it supports accurate preload setting and clearance matching for different industrial application scenarios.
Load-Bearing Advantage: Enhanced overall rigidity is realized through double-row symmetric structure, capable of coping with heavy radial loads and dual-direction axial loads while keeping internal forces evenly distributed.
4. Load-Carrying Capacity
Radial Load Capacity: Markedly improves radial load bearing performance relative to single-row tapered roller bearings, applicable to sustained heavy-duty running work.
Load Type Adaptability: Optimized structure adapts well to integrated load situations dominated by radial loads and equipped with bidirectional axial loads, capable of continuous operation under heavy loads, alternating dynamic loads and shock loads.
5. Performance Characteristics
Limiting Speed: With well-designed tapered roller contact structure and balanced friction matching, the bearing operates steadily in medium-low speed heavy-load scenarios, presenting low running noise and small friction consumption.
Axial Load Capacity: Unlike single-row structures that only support one-way axial bearing, double-row symmetrical layout carries stable bidirectional axial thrust, completes accurate shaft system axial positioning and relieves axial displacement and mechanical vibration efficiently.
Operational Stability: Scientific roller distribution and optimized raceway contact greatly lower operational deflection and abrasion degree, meeting the demand of long-term stable continuous operation under harsh industrial working conditions.
6. Material & Manufacturing
Inner & Outer Rings: Composed of high-purity bearing steel, characterized by high hardness and superb deformation resistance.
Rolling Elements: High-precision tapered rollers realize uniform stress bearing and exceptional wear resistance.
Cage: High-strength rigid retainer effectively avoids roller deviation and internal collision friction.
Heat Treatment: Integrated thermal treatment including quenching and tempering improves surface hardness, integral fatigue performance and service life, adapting to long-cycle industrial working environment.
7. Application Fields
Primary Application: Extensively fitted for roll neck support, transmission support and auxiliary bearing positions of various steel rolling mills and metallurgical devices.
Other Applications: Available for heavy machinery equipment with strict requirements on rigidity and bidirectional load resistance, applicable to mining, engineering machinery, heavy gearboxes and complete industrial transmission systems.
