3. Structural Features
Component Composition: Fitted with two groups of tapered rollers, double-row race inner ring, monolithic outer ring and high-stiffness precision cage, the bearing features neat compact layout and superior structural integration property.
Clearance Adjustment: Independent adjustable internal clearance structure realizes accurate preload and clearance adjustment for different mechanical operation environments.
Load-Bearing Advantage: Optimized symmetrical double-row structure improves integral bearing rigidity effectively, enduring heavy radial loads and two-way axial loads with balanced internal force spread.
4. Load-Carrying Capacity
Radial Load Capacity: It possesses far stronger radial load bearing capacity than single-row tapered roller bearings, perfectly fit for long-term heavy-load operation of metallurgical and rolling mill equipment.
Load Type Adaptability: Optimized for steel mill composite loads with radial loads as primary stress and bidirectional axial loads as auxiliary stress, it reliably withstands continuous rolling heavy loads, alternating loads and equipment shock loads.
5. Performance Characteristics
Limiting Speed: Equipped with dedicated tapered roller contact geometry and well-matched friction assemblies, the bearing maintains stable performance under medium-low speed heavy-load conditions, featuring quiet operation and minimal friction energy consumption.
Axial Load Capacity: Unlike single-row tapered roller bearings that only support unidirectional axial loads, its symmetrical double-row construction steadily withstands bidirectional axial thrust. It enables precise axial positioning of shaft assemblies and effectively counteracts axial shift and operating vibration.
Operational Stability: Optimized roller layout and high-precision raceway contact drastically cut running deflection and component abrasion, supporting long-term uninterrupted stable operation in severe industrial environments.
6. Material & Manufacturing
Inner & Outer Rings: High-purity premium bearing steel is selected as raw material, granting superior hardness and stable anti-distortion performance.
Rolling Elements: Precisely fabricated tapered rollers support balanced load stress and feature premium anti-abrasion characteristics.
Cage: Heavy-duty high-strength rigid retainer restrains roller displacement and eliminates collision contact between rolling bodies.
Heat Treatment: A full-piece quenching and tempering thermal process is applied to enhance surface hardness and comprehensive fatigue durability, extending service lifespan and meeting long-term industrial application specifications.
7. Application Fields
Primary Application: Widely used to support roll necks, transmission parts and auxiliary bearing positions of steel rolling mills and metallurgical machinery.
Other Applications: Suitable for all heavy-load machinery requiring high stiffness and bidirectional load bearing, such as mining machines, construction equipment, heavy gear boxes and industrial drive systems.
