Product Overview

Double Row Taper Roller Bearings are heavy-duty precision bearings engineered to accommodate high combined radial and bidirectional axial loads within a compact arrangement. Featuring two rows of tapered rollers running between a common double-outer ring (cup) and two inner rings (cones), or vice versa, these bearings offer enhanced structural rigidity and substantial load ratings. Manufactured from high-purity GCr15 Chrome Steel or premium case-hardened alloy steel, they are designed with predetermined internal axial clearances to ensure precise shaft alignment and rotational performance under dynamic stresses. Double row tapered roller bearings are widely specified across automotive wheel hubs, industrial gearboxes, rolling mills, mining machinery, heavy hoisting equipment, and agricultural machinery.

Key Features & Advantages

Superior Combined & Bidirectional Axial Load Capacity: Designed to support heavy radial loads while simultaneously handling substantial axial forces acting in both directions.

High Rigidity & Moment Resistance: The wide effective bearing distance provided by the double-row arrangement delivers high moment stiffness, resisting tilting forces and structural shaft deflections.

Preset Internal Clearance: Precision-engineered factory spacer settings eliminate the need for complex manual clearance adjustments during installation, streamlining assembly and maintenance.

High Shock & Impact Resistance: Premium case-hardened steel options offer a hard wear-resistant surface combined with a ductile inner core, providing high resistance to heavy shock loads.

Long Service Life & Low Friction: Optimized roller-to-raceway contact geometry reduces edge stress concentrations, ensuring smooth running accuracy and extended operational lifespan.
