3. Structural Features
Component Composition: The bearing unit includes dual tapered roller groups, double-row raceway inner ring, seamless integrated outer ring and high-precision rigid cage with compact and highly integrated construction.
Clearance Adjustment: The built-in adjustable clearance structure enables accurate preload regulation and clearance resetting to adapt to varied working conditions.
Load-Bearing Advantage: The design greatly improves structural rigidity, allowing simultaneous bearing of dominant radial and bidirectional axial loads with consistent internal force transmission.
4. Load-Carrying Capacity
Radial Load Capacity: Outstanding radial load bearing capacity is achieved over single-row tapered roller bearings, to meet the demands of extended heavy-load operation.
Load Type Adaptability: Precisely designed for compound load conditions with primary radial loads and secondary bidirectional axial loads, it reliably sustains persistent heavy loads, cyclic alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Special tapered roller contact structure and perfectly coordinated friction components grant the bearing stable working performance at medium and low heavy-load speeds, marked by low noise emission and minor friction power loss.
Axial Load Capacity: Where single-row tapered roller bearings are restricted to unidirectional axial load bearing, the symmetric double-row layout delivers reliable bidirectional axial thrust bearing capacity. It enables precise axial alignment of shaft systems and efficiently counteracts axial displacement and vibration produced during equipment operation.
Operational Stability: Scientific refined roller distribution and high-precision optimized raceway fit minimize operational deviation and mechanical wear, adapting to harsh industrial working scenes for long-cycle uninterrupted stable operation.
6. Material & Manufacturing
Inner & Outer Rings: Made of high-purity bearing steel, these components offer high hardness and robust structural stability with excellent deformation resistance.
Rolling Elements: Our precision-machined tapered rollers come with evenly balanced internal stress and remarkable anti-wear properties.
Cage: A high-toughness rigid cage serves to effectively stop roller misalignment and mutual impact.
Heat Treatment: Integrated quenching and tempering processes raise surface hardness, boost fatigue endurance and prolong service life, meeting the requirements of prolonged continuous industrial operation.
7. Application Fields
Primary Application: Specially applied to roll neck support points, transmission load-bearing frames and auxiliary bearing seats of various rolling mill stands and metallurgical continuous production equipment.
Other Applications: Optimized for heavy metallurgy, mining and construction machinery that demands ultra-high rigidity and stable bidirectional load capacity, including mining heavy equipment, engineering machinery, large heavy gear reducers and factory industrial power transmission assemblies.
