3. Structural Features
Component Composition: This bearing includes two sets of tapered rollers, double-row race inner ring, one-piece outer ring and high-stiffness precision cage, featuring compact layout and high structural integration.
Clearance Adjustment: It adopts adjustable internal clearance design to achieve precise preload and clearance adjustment for various working environments.
Load-Bearing Advantage: Optimized double-row symmetrical structure improves overall rigidity, capable of bearing large radial loads and two-way axial loads with balanced internal force distribution.
4. Load-Carrying Capacity
Radial Load Capacity: Great progress in radial load bearing performance is made compared with single-row tapered roller bearings, applicable to any extended heavy-duty working application.
Load Type Adaptability: Suited for comprehensive mixed loads that take radial force as the core load and two-way axial force as assistance, it provides reliable bearing capacity against sustained heavy loads, alternating loads and mechanical impact loads.
5. Performance Characteristics
Limiting Speed: Utilizing unique tapered roller contact structure and rationally matched friction pairs, this bearing retains stable working performance during medium-low speed heavy-duty operation, with low noise emission and limited friction power wastage.
Axial Load Capacity: Different from single-row tapered roller bearings restricted to single-direction axial loads, the symmetric double-row layout stably endures two-way axial thrust. It achieves precise axial alignment for shaft systems and mitigates axial shift and mechanical vibration effectively.
Operational Stability: Polished roller distribution and upgraded raceway contact greatly lower running deviation and abrasion loss, adapting to complicated harsh industrial sites for long-cycle consistent operation.
6. Material & Manufacturing
Inner & Outer Rings: Inner and outer rings are forged with high-purity premium bearing steel, boasting high hardness and steady ability to resist load deformation.
Rolling Elements: Ultra-precision processed tapered rollers realize balanced internal stress transmission and superior abrasion resistance.
Cage: Tough high-strength rigid cage controls roller movement range and stops collision contact efficiently.
Heat Treatment: We adopt integral quenching and tempering craftsmanship to upgrade surface hardness and whole-piece fatigue resistance, extending service life and matching long-cycle industrial working standards.
7. Application Fields
Primary Application: Commonly arranged at roll neck supports, transmission supports and auxiliary bearing spots for stable operation of steel rolling and metallurgical machinery.
Other Applications: Adaptable to heavy-load mechanical equipment featuring high structural stiffness and stable bidirectional load resistance, such as mining machines, engineering construction machinery, heavy-duty gear boxes and industrial transmission drive systems.
