Description

Manufacturing Process of DAC Wheel Bearing

  1. Material Selection

    • High-quality bearing steel (e.g., SAE 52100) is chosen for durability and wear resistance.

  2. Forging

    • Raw steel is heated and forged into the desired ring shape.

  3. Turning (Machining)

    • The inner and outer rings are precisely machined to meet design specifications.

  4. Heat Treatment

    • Rings are hardened using heat treatment to increase strength and wear resistance.

  5. Grinding & Superfinishing

    • Precision grinding ensures smooth surfaces and accurate dimensions.

  6. Bearing Assembly

    • Rolling elements (balls) and cages are inserted, and the bearing is assembled with seals and grease.

  7. Quality Inspection

    • Bearings undergo rigorous testing for dimensional accuracy, load capacity, and durability.

  8. Packing & Distribution

    • Final products are cleaned, lubricated, packed, and distributed to automotive manufacturers or aftermarket suppliers.
