Product Type: Double-Row Tapered Roller Bearing
Model No.: 372952X2-1
1. Overview
Classified as high-strength structural bearings, double-row tapered roller bearings are developed to handle harsh heavy-duty service conditions. Boasting high rigidity, consistent operation and robust combined load bearing capability, they are widely adopted as core supporting components within metallurgy, mining and heavy industry machinery.

3. Structural Features
Component Composition: Featuring dual tapered roller sets, double-row raceway inner ring, one-piece outer ring and high-precision rigid cage, the bearing is compact and highly integrated.
Clearance Adjustment: Its internal adjustable clearance design allows precise preload regulation and clearance calibration for specific working scenarios.
Load-Bearing Advantage: Improved overall rigidity comes from this design; it handles main radial and bidirectional axial loads together with uniform internal force delivery.
4. Load-Carrying Capacity
Radial Load Capacity: It delivers far stronger radial load bearing capacity than single-row tapered roller bearings, satisfying the long-duration heavy-load operation requirements of rolling mills and metallurgical equipment.
Load Type Adaptability: Optimized for metallurgical compound load environments dominated by radial loads and matched with bidirectional axial loads, it reliably withstands sustained heavy rolling loads, cyclic alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Proprietary tapered roller contact framework and harmonized friction component matching maintain consistent stable performance at medium and low heavy-load speeds, featuring silent rotation and small friction power loss.
Axial Load Capacity: Distinct from single-row tapered roller bearings confined to unidirectional axial loads, the double-row symmetric layout steadily carries two-way axial thrust. It realizes precise axial positioning for shaft parts and eliminates axial displacement and running vibration of industrial machinery efficiently.
Operational Stability: Elaborate roller arrangement and high-quality raceway fit minimize running deviation and mechanical wear loss, perfectly suited for long-term uninterrupted stable operation in complex harsh industrial sites.
6. Material & Manufacturing
Inner & Outer Rings: Premium high-purity bearing steel material offers reliable high hardness and stable anti-deformation capacity for heavy-load applications.
Rolling Elements: Carefully crafted tapered rollers support evenly distributed stress bearing and excellent top-class wear-resistant property.
Cage: Long-service rigid cage with high tensile strength efficiently limits roller displacement and collision contact.
Heat Treatment: We apply monolithic quenching and tempering to upgrade surface hardness and overall fatigue resistance, extend service life and satisfy standardized long-cycle industrial usage requirements.
7. Application Fields
Primary Application: Mainly fitted to undertake supporting work at roll neck positions, transmission supporting structures and auxiliary bearing mounting points for steel rolling and metallurgical production facilities.
Other Applications: Compatible with diverse heavy industrial equipment with strict standards for high rigidity and stable dual-direction load capacity, including mining machinery, road construction equipment, heavy gear reducers and industrial drive assemblies.
