Features and characteristics

  • High Precision Adopts advanced precision machining technology to deliver extremely high dimensional accuracy (e.g., inner diameter 42mm, outer diameter 82mm, height 36mm). This guarantees accurate guidance for wheel hub rotations and ensures overall vehicle stability.
  • Double Row Angular Contact Structure Features a double row angular contact ball bearing setup designed to support complex combined radial and axial loads simultaneously, making it highly adaptable to extreme cornering and road forces.
  • High-Quality Materials Manufactured from high-carbon chromium bearing steel (GCr15), providing superior strength, exceptional hardness, and outstanding wear resistance for reliable performance under heavy usage.
  • Advanced Seal Design Equipped with a highly effective composite sealing system consisting of premium nitrile rubber and an SPCC steel skeleton. This keeps lubricating grease securely sealed inside while blocking moisture, dust, and other external contaminants to prolong operational lifespan.

Performance Advantages

Strong Load Capacity

Handles demanding static and dynamic loads effortlessly, supporting the overall weight of the vehicle, cargo, and passengers under varying driving conditions.

Low Friction Torque

Designed with an optimized internal geometry that lowers friction torque, aiding in vehicle fuel efficiency and reducing internal heat build-up.

Superb Rotation Accuracy

Provides highly accurate rotation at high velocities, minimizing system vibration, dropping cabin noise, and optimizing ride comfort.

High Durability

Maintains solid, consistent performance even in challenging environmental factors like high humidity, elevated temperatures, and sandy terrains.

Target Application Models

Widely applicable to modern sedan structures, specifically optimizing front-wheel performance across various compatible European and regional platforms.

Maintenance & Operational Guidelines

Regular Inspection

  • Rotation Check Raise the vehicle's axle and spin the wheel manually. Inspect for tight spots or abnormal grinding noises. Uneven rotation usually points to standard bearing wear or misalignment.
  • Play/Swing Check Grasp the tire firmly from the top and bottom and apply reciprocal force. Any noticeable wiggle or structural play calls for immediate hub disassembly and adjustment.
  • Visual Inspection Check the interior tire wall for grease or oil spots. Wet residues can indicate failed hub seals or brake fluid leakage, both requiring timely troubleshooting.

Correct Maintenance Process

  • Safety & Clean Prep Secure the vehicle on solid jack stands. Remove the tire, dust cover, axle nut, and brake assembly to gain clear access to the hub housing.
  • Cleaning & Inspection Extract the old bearing, thoroughly cleaning all old grease from the hub cavity and shaft spindle. Look closely for spalling, micro-cracks, or pitting on the raceways; replace if detected.
  • Grease Application Apply premium high-temperature bearing grease deep into the roller elements and the central hub cavity. Avoid over-greasing to prevent heat traps.
  • Re-installation Carefully press-fit components, and tighten all lock plates and spindle nuts to the precise manufacturer-specified torque limits before lowering the vehicle.
