Introduction of suspension ball joint：
Suspension ball joint is a common joint device in automobiles, also known as a ball hinge. It consists of a steel ball and a ball bowl. The steel ball can rotate freely in the ball bowl. Our suspension ball joint is widely used in parts such as the steering lever and suspension swing arm of the automobile to achieve flexible connection. The role of ball joint for BMW is to connect two objects and allow them to rotate relative to each other within a certain range, which is different from a simple hinge; The use of ball joint for BMW can achieve rotation movement. The structure of ball joint for BMW is simple and efficient, so that all parts of the car can move smoothly.
Parameters of ball joint for BMW：
| Category | Parameter value |
| Material | High-carbon chromium alloy steel (quenching process) or zinc alloy metallurgical technology |
| Tensile strength | ≥800 MPa |
| Improved wear resistance | More than 50% |
| Lubrication system | Built-in special grease (lithium-based or PTFE), temperature resistance range: -30℃~120℃, waterproof and dustproof |
| Surface treatment | Galvanized/phosphated treatment or stainless steel material, suitable for salt spray, humid environment, extend life |
| Friction design | Low friction joints (precision polishing), steering resistance is reduced by 20%, and the steering wheel is responsive |
| Load capacity | Dynamic load bearing capacity ≥2000 kg, suitable for heavy-duty scenarios (such as SUVs and commercial vehicles) |
Attribute advantage：
The attribute advantages of our lower ball joint are reflected in its high-carbon chromium alloy steel material and quenching process. The tensile strength of this ball joint is ≥800MPa, which guarantees the ultra-high strength and wear resistance of the ball joint. Our lower ball joint's long-lasting lubrication system uses lithium-based or PTFE grease, with a temperature range of -30℃~120℃, waterproof and dustproof, to avoid abnormal noise of ball joint dry grinding. Our lower ball joint anti-rust and anti-corrosion treatment such as galvanized process can extend the life of front ball joint for BMW.
Product advantage：
The low-friction design of our front ball joint for BMW reduces steering resistance by 20% through precision polishing of the joints and improves the response sensitivity of the front ball joint for BMW. The high load capacity is up to 2000kg, making front ball joint for BMW suitable for heavy-duty scenarios such as SUV. The internal structure of front ball joint for BMW can absorb shock and buffer, reducing transmission bumps. The anti-shedding structure of our lower ball joint, such as the locking circlip process, prevents the ball joint from prolapse out of control and ensures the safety of the lower ball joint. Ourlower ball joint uses a multi-layer sealed dust cover to block sediment moisture and reduce lower ball joint wear. The fatigue test of our lower ball joint passed 100,000 swings without deformation.
