Auto Ball Joint Wholesale

Auto Ball Joints are pivotal components in a vehicle’s suspension system, acting as the movable connection between control arms and steering knuckles. They enable smooth rotational movement, absorb road shocks, and maintain proper wheel alignment, directly affecting steering precision, handling, and safety. Anhui Tianyu Auto Parts Manufacturing Co., Ltd. produces high-quality Auto Ball Joints engineered for durability and consistent performance.

1. Core Definition & Function

• Definition: A ball joint is a spherical bearing that connects suspension components, allowing controlled movement in multiple directions.

• Function: Transfers loads between control arms and wheel knuckles, supports vehicle weight, absorbs shocks, and maintains alignment during steering and suspension movement.

2. Materials & Manufacturing

• Materials: Alloy steel, carbon steel, and precision bearing components.

• Manufacturing Process: Heat-treated for strength, anti-corrosion coatings for durability, precision machining for exact tolerances.

• Quality Control: Tianyu uses modern workshops and a multi-million RMB R&D lab to ensure OEM-compliant dimensions and performance.

3. Structure Types & Design

Auto Ball Joints are classified based on load capacity and installation type:

4. Key Components & Connection Points
