IV. Detailed Description

High-Quality Construction & Materials

This hub bearing assembly is made of high-strength steel alloy, processed by precision machining to ensure durability and fatigue resistance when bearing vehicle loads. The surface is treated with anti-rust technology (presenting a metallic luster as shown in the picture), and the flange part has excellent structural strength.

Integrated ABS Sensor Technology

The product is pre-installed with a high-performance integrated ABS wheel speed sensor (the black cover part shown in the picture).
  • Connector Type: 2-pin rectangular socket, ensuring seamless connection with the original vehicle wiring harness.
  • Protection Design: The sensor is encapsulated in a dust-proof and waterproof black composite material housing, effectively preventing the intrusion of muddy water and road debris, and ensuring accurate and stable signal transmission of the ABS system.

Precision Sealing Design

The bearing is equipped with a multi-lip seal design inside and pre-filled with high-temperature resistant grease at the factory. This maintenance-free design effectively prevents lubricating oil leakage, blocks external pollutants, and significantly extends the service life of the bearing.

Plug-and-Play Installation

The assembly includes a complete hub flange, precision bearing, and 5 pre-pressed wheel studs. The 4-bolt flange mounting design complies with original factory specifications, no additional pressing operation is required, and it can directly replace old parts, reducing installation man-hours.
