Performance & Characteristics

High Load-Bearing Capacity

Engineered to reliably withstand both the static vehicle weight (radial load) and dynamic lateral cornering and braking forces (axial load).

Dynamic Operational Stability

Optimized structural design dampens road shocks and harsh vibrations under severe conditions, rough terrain, or emergency braking.

Low Friction Coefficient

Precision-finished raceways and premium rolling elements minimize operational friction, ensuring smooth wheel rotation and maximizing vehicle fuel economy.

High Rotational Precision

Maintains strict coaxiality and perpendicularity of the wheel hub assembly, reducing cabin noise, vibration, and harshness (NVH) while driving.

Superior Reliability & Longevity

Manufactured using premium vacuum-degassed chrome bearing steel (GCr15) with dedicated heat treatment for enhanced hardness and wear resistance.

Application & Fitment

Widely Applicable Vehicle Models

Commonly applied to passenger cars, compact vehicles, and commercial platforms including Foton Midi, Great Wall Mini, Fengxing S500, Jingyi X3/X5, and equivalent global automotive platforms requiring dependable wheel-end performance.

Streamlined Installation

Engineered as a direct-fit unit that mounts directly to the vehicle hub spindle. Eliminates complicated clearance adjustments during assembly, significantly lowering maintenance time and labor costs.

Structural Features

Double-Row Structure

Built with double-row angular contact ball or tapered roller construction to support bidirectional thrust and heavy radial loads with enhanced rigidity.

Multi-Lip Seal Design

Equipped with heavy-duty contact rubber seals (2RS/DDU) to lock lubricant inside while locking out road grime, water, salt, and abrasive contaminants.

Integrated System Readiness

Compatible with modern electronic vehicle systems, accommodating integrated ABS sensor rings and magnetic encoders for accurate wheel speed measurement.
