3. Structural Features
Component Composition: This bearing consists of two sets of tapered rollers, double-row raceway inner ring, one-piece outer ring and high-precision rigid cage, presenting compact overall structure and superior integrated performance.
Clearance Adjustment: It adopts adjustable internal clearance structure, which realizes accurate preload configuration and clearance regulation according to actual operating conditions.
Load-Bearing Advantage: The symmetrical double-row structure effectively enhances overall rigidity, enabling simultaneous bearing of heavy radial loads and bidirectional axial loads with uniformly distributed internal stress.
4. Load-Carrying Capacity
Radial Load Capacity: Remarkably upgraded radial load carrying performance makes it far superior to single-row tapered roller bearings, suitable for long-time heavy-load mechanical operation.
Load Type Adaptability: Suited for diversified combined load scenes centered on radial loads and assisted by two-way axial loads, it can steadily take heavy loads, alternating fatigue loads and impact vibration loads for continuous production.
5. Performance Characteristics
Limiting Speed: Equipped with optimized tapered roller contact structure and matched friction components, it keeps stable operation under medium and low speed heavy-duty working conditions, owning low noise and energy-saving friction performance.
Axial Load Capacity: It can bear stable bidirectional axial thrust relying on double-row symmetrical structure, different from single-row bearings that only carry unidirectional axial loads. It realizes precise axial fixation of shafts and reduces axial displacement and vibration during mechanical operation.
Operational Stability: Delicately designed roller arrangement and fitted raceway structure greatly improve running smoothness and reduce wear, enabling long-term reliable operation in harsh industrial working scenes.
6. Material & Manufacturing
Inner & Outer Rings: Made of refined high-purity bearing steel, the rings boast high mechanical hardness and superb anti-distortion performance.
Rolling Elements: Precision manufactured tapered rollers feature even stress distribution and strong durable wear resistance.
Cage: High-toughness rigid cage structure effectively solves the problems of roller deflection and mutual collision.
Heat Treatment: Overall quenching plus tempering improves comprehensive performance, increases surface hardness and fatigue resistance, and meets all standards for long-period industrial equipment use.
7. Application Fields
Primary Application: Its main application scenarios include roll neck support, transmission support and auxiliary bearing installation areas within steel rolling and metallurgical industries.
Other Applications: Compatible with diverse heavy-load equipment that needs excellent rigidity and bidirectional load adaptability, including mining facilities, engineering machinery, heavy gear transmission boxes and industrial power transmission equipment.
