3. Structural Features
Component Composition: Made up of two matched tapered roller groups, double-row race inner ring, integral formed outer ring and high-rigidity precision cage, it features compact layout and high assembly integration.
Clearance Adjustment: Featured with adjustable inner clearance structure, accurate preload configuration and clearance control can be completed to adapt to varied mechanical working environments.
Load-Bearing Advantage: Rational double-row symmetric design enhances overall bearing rigidity efficiently, undertaking large radial loads and bidirectional axial loads while maintaining balanced internal force distribution.
4. Load-Carrying Capacity
Radial Load Capacity: A dramatic improvement in radial load bearing strength is realized against single-row tapered roller bearings, fitting all kinds of extended heavy-load working occasions.
Load Type Adaptability: Refined for mixed load states with primary radial loads and secondary bidirectional axial loads, it provides reliable endurance to sustained heavy loads, frequent alternating loads and mechanical vibration impact loads.
5. Performance Characteristics
Limiting Speed: The combination of well-designed tapered roller contact structure and properly matched friction pairs delivers smooth rotation for the bearing under medium-low speed heavy-load states, alongside low noise and low friction consumption.
Axial Load Capacity: While single-row tapered roller bearings only handle unidirectional axial loads, the symmetric double-row construction endures steady two-way axial thrust. It ensures accurate axial positioning of shaft assemblies and effectively removes axial displacement and vibration from running machinery.
Operational Stability: Upgraded roller layout and precise raceway contact minimize operational deflection and abrasion, offering durable stable continuous operation in all types of severe industrial working environments.
6. Material & Manufacturing
Inner & Outer Rings: Inner and outer rings are crafted from pure high-quality bearing steel, featuring excellent hardness and reliable capability to resist structural deformation.
Rolling Elements: Exquisitely finished tapered rollers disperse stress evenly and maintain remarkable abrasion-proof performance over long service times.
Cage: High-rigidity reinforced cage efficiently limits roller deflection and cuts down impact friction between rollers.
Heat Treatment: We apply monolithic quenching and tempering technology to enhance surface hardness and fatigue resistance, extending service life for prolonged industrial production operation.
7. Application Fields
Primary Application: Their core usage covers load support for roll necks, transmission components and auxiliary bearing positions of steel rolling mills and metallurgical machinery sets.
Other Applications: Compatible with diverse heavy-duty mechanical equipment with requirements for high rigidity and dual-way load resistance, such as mining machinery, road construction equipment, heavy gear boxes and industrial drive assemblies.
