Product Type: Double-Row Tapered Roller Bearing
1. Overview
Double-row tapered roller bearings are high-strength structural bearings engineered for rigorous heavy-duty industrial environments. They possess outstanding rigidity, smooth rotational performance and remarkable integrated load capacity, readily adapting to multi-load complex working scenarios, and function as critical supporting elements for metallurgical, mining and heavy-duty machinery.

3. Structural Features
Component Composition: Formed by two tapered roller assemblies, double-groove inner ring, solid outer ring and high-precision sturdy cage, it boasts compact structure and outstanding structural integration.
Clearance Adjustment: Built with an adjustable internal clearance system, it allows accurate preload configuration and gap regulation to suit diverse field working conditions.
Load-Bearing Advantage: The symmetric double-row design markedly elevates overall stiffness, enabling it to sustain substantial radial loads and two-way axial loads with evenly spread internal stress.
4. Load-Carrying Capacity
Radial Load Capacity: Effectively elevates radial load bearing limit compared with single-row tapered roller bearings, adapting to long-term high-load stable operation.
Load Type Adaptability: Designed for comprehensive composite loads mainly bearing radial loads and auxiliary bidirectional axial loads, it can stably withstand heavy loads, frequent alternating loads and sudden mechanical impact loads.
5. Performance Characteristics
Limiting Speed: The matched tapered roller contact structure ensures stable performance at medium and low speeds under heavy loads, with low noise and low friction loss.
Axial Load Capacity: It can bear steady bidirectional axial thrust different from single-row bearings for one-way axial load only, achieving precise shaft positioning and reducing operational axial displacement and vibration.
Operational Stability: Optimized roller and raceway structure reduces deviation and wear, enabling long-term stable continuous operation in harsh industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: High-grade pure bearing steel ensures stable high hardness and strong resistance to pressure deformation.
Rolling Elements: Elaborately processed tapered rollers bear force evenly and feature long-lasting wear resistance.
Cage: Robust high-strength cage structure effectively prevents roller dislocation and mutual collision.
Heat Treatment: Entire bearing adopts quenching and tempering heat treatment to elevate surface hardness, fatigue endurance and service life, fully meeting long-term industrial operating criteria.
7. Application Fields
Primary Application: Broadly used to bear loads for roll necks, transmission parts and auxiliary bearing structures on rolling mill and metallurgical operational equipment.
Other Applications: Designed for diverse heavy-duty machinery requiring high stiffness and bidirectional load bearing capability, involving mining machinery, construction machinery, heavy gear assemblies and industrial transmission mechanism.
