What is the weight of BMW 3 Series wheel hubs?
1 Answers
Due to the numerous models of the BMW 3 Series, the sizes of its wheel hubs vary, with weights approximately ranging from 9.2 to 13 kilograms. Overview of automotive wheel hubs: Automotive wheel hubs refer to the components used to bear the rigid rotational inertia between the vehicle and the tires, also known as rims or steel rings. A complete wheel hub unit includes the automotive bearing, also known as the flange, which works with the tire to support the wheel. Types of automotive wheel hubs: Depending on the characteristics and requirements of different vehicle models, the surface treatment processes for wheel hubs also vary, mainly divided into painting and electroplating. For ordinary vehicle models, less consideration is given to the appearance of the wheel hubs, with good heat dissipation being a basic requirement. The process generally involves painting treatment, which means spraying first and then baking, offering economical costs, bright colors, and long-lasting durability. Even if the vehicle is scrapped, the color of the wheel hubs remains unchanged.
