Product Type: Double-Row Tapered Roller Bearing
Model No.: 372952X2
1. Overview
Double-row tapered roller bearings are high-strength structural bearings built to withstand rigorous heavy-duty working environments. With outstanding rigidity, stable running characteristics and reliable resistance to combined loads, they are extensively used as key support parts in metallurgical, mining and heavy industrial equipment.

3. Structural Features
Component Composition: Composed of dual tapered roller units, double-row raceway inner ring, integrated outer ring and high-precision rigid cage, it has a compact, highly integrated structure.
Clearance Adjustment: Fitted with internal adjustable clearance, it enables fine preload and clearance adjustment per actual working requirements.
Load-Bearing Advantage: The structure greatly increases overall rigidity, supporting simultaneous dominant radial and bidirectional axial loads with even internal force distribution.
4. Load-Carrying Capacity
Radial Load Capacity: Its radial load bearing capability surpasses single-row tapered roller bearings, perfectly meeting the requirements for prolonged heavy-load operation.
Load Type Adaptability: Tailored for mixed load environments with radial loads as the main load and bidirectional axial loads as complement, it maintains stable performance under persistent heavy loads, cyclic alternating loads and mechanical shock loads.
5. Performance Characteristics
Limiting Speed: Specially designed tapered roller contact structure and rationally fitted friction components keep the bearing running smoothly under medium-low speed heavy loads, with low noise output and negligible friction energy waste.
Axial Load Capacity: While single-row tapered roller bearings merely withstand unidirectional axial thrust, the symmetric double-row construction provides stable bidirectional axial load resistance. It enables accurate axial fixation of shaft systems and counteracts axial shift and mechanical vibration during continuous operation.
Operational Stability: Polished roller distribution and precision-optimized raceway contact drastically reduce operational deflection and surface abrasion, guaranteeing long-cycle steady continuous work amid rigorous industrial operating conditions.
6. Material & Manufacturing
Inner & Outer Rings: Inner and outer ring components adopt premium pure bearing steel, possessing high hardness and consistent anti-distortion capability.
Rolling Elements: Precision polished tapered rollers realize uniform stress transmission and top-tier abrasion-resistant characteristics.
Cage: Durable reinforced high-strength rigid cage prevents roller shifting and direct collision contact.
Heat Treatment: Entire-bearing quenching and tempering treatment boosts surface hardness and integral fatigue endurance, prolongs service cycles and complies with long-term industrial working norms.
7. Application Fields
Primary Application: Extensively deployed to bear loads for roll necks, transmission supporting fittings and auxiliary bearing installation sites of steel rolling and metallurgical production machinery.
Other Applications: Well-suited for heavy-duty mechanical apparatus requiring excellent stiffness and reliable bidirectional load resistance, such as mining machines, engineering machinery, heavy gear reduction boxes and industrial power transmission mechanisms.
