IV. Appearance & Detail Description

Overall Structure

• Flange: Made of high-strength matte gray cast iron, with a fine granular casting texture on the surface, ensuring excellent load-bearing capacity and corrosion resistance.
• Bearing Part: Made of high-quality bright bearing steel, processed by precision turning and polishing, showing a smooth metallic luster, reducing friction during operation and ensuring stable rotation.

Flange Details

• The flange surface is designed in a standard circular shape, with 4 evenly distributed internal threaded holes, which are used to connect with wheels or suspension components. The edges of the holes are chamfered to avoid thread damage during installation and facilitate quick assembly.
• A small positioning hole is reserved on the flange surface, which can realize precise positioning during installation, avoid deviation, and improve installation efficiency.
• The surface of the flange is laser-engraved with HJDP brand logo, model code and production batch information, which is convenient for product traceability and genuine authentication, ensuring that customers can use it with confidence.

Bearing Assembly Details

• The bearing adopts a double-row angular contact structure, which can bear both radial and axial loads, effectively improving the stability and service life of the bearing, and adapting to the driving needs of different road conditions.
• A black high-elasticity rubber seal ring is embedded between the inner and outer rings of the bearing, and the production batch number is printed on the surface of the seal ring for quality traceability. The seal ring can effectively lock the internal pre-filled high-temperature resistant lubricating grease and prevent the intrusion of muddy water, dust and other pollutants.
• The inner hole of the bearing is a smooth cylindrical surface, which is closely matched with the half shaft or hub shaft, ensuring stable power transmission and reducing driving vibration and noise.
• The bearing and flange are combined by interference press-fitting, with a uniform metal cutting step at the transition position, ensuring firm connection and no looseness during long-term use.

V. Product Advantages

• Precise Compatibility: Covers multiple classic models of Volkswagen and Audi, with multiple interchangeable OE numbers, ensuring OE-level fitment, no modification required, and direct replacement of old parts.
• Superior Quality: Made of high-strength cast iron and bearing steel, through strict heat treatment and precision machining, with excellent wear resistance, anti-fatigue performance and corrosion resistance, meeting the long-term use needs of vehicles.
• Easy Installation: Integrated design with precise positioning hole, pre-installed structure, no additional pressing operation required, which can greatly reduce installation man-hours and labor costs, suitable for professional repair shops and individual replacement.
• Stable & Quiet Performance: Double-row angular contact bearing and high-quality seal ring design, ensuring smooth rotation, reducing driving noise and vibration, and improving driving comfort.
• Cost-Effective: With competitive reference price and OE-level quality, it is a cost-effective choice for automotive aftermarket replacement, balancing quality and cost.
