3. Structural Features
Component Composition: Assembled by two matched tapered roller parts, double-row race inner ring, whole-piece outer ring and high-precision sturdy retainer, it has compact exterior and highly integrated internal structure.
Clearance Adjustment: Featured with flexible adjustable clearance inside, it can complete precise preload configuration and clearance adaptation for diverse mechanical operation environments.
Load-Bearing Advantage: Scientific double-row symmetric structure enhances overall bearing stiffness greatly, capable of enduring heavy radial loads and two-way axial loads with balanced internal force operation.
4. Load-Carrying Capacity
Radial Load Capacity: It provides more powerful radial load support than single-row tapered roller bearings, perfectly matching the demands of long-term heavy-load continuous operation.
Load Type Adaptability: Optimized structure adapts well to integrated load conditions with radial loads as priority and bidirectional axial loads as complement, ensuring stable service while bearing heavy loads, alternating loads and impact loads.
5. Performance Characteristics
Limiting Speed: Reasonable friction coordination together with tapered roller contact design ensures stable operation of the bearing in medium-low speed heavy-load working states, with outstanding mute effect and low friction loss.
Axial Load Capacity: This bearing features bidirectional axial load bearing capacity via double-row symmetric design, which single-row tapered roller bearings cannot achieve. It accurately positions shaft components axially and mitigates axial displacement and equipment running vibration effectively.
Operational Stability: Streamlined roller layout and high-precision raceway assembly effectively reduce operational deviation and wear loss, fully satisfying long-cycle continuous stable operation demands.
6. Material & Manufacturing
Inner & Outer Rings: Premium high-purity bearing steel ensures stable hardness and excellent deformation resisting effect for inner and outer rings.
Rolling Elements: Meticulously polished tapered rollers realize balanced force bearing and outstanding anti-abrasion effect.
Cage: Heavy-duty rigid cage effectively controls roller movement and prevents abnormal collision between rollers.
Heat Treatment: Integral heat treatment including quenching and tempering greatly promotes surface hardness and integral fatigue resistance, fully fitting long-term heavy-duty industrial working demands.
7. Application Fields
Primary Application: Greatly popular for roll neck load support, transmission part support and auxiliary bearing assembly places of rolling mills and related metallurgical machinery.
Other Applications: Designed to match heavy-duty working machinery requiring high stiffness and bidirectional pressure resistance, involving mining machines, road construction machinery, heavy gear components and industrial transmission mechanisms.
