  There are mainly two types of ball pin structures: one is the combined type of ball pin and integral ball socket, and the other is the combined type of hemispherical ball pin and spherical component
In the past, spiral springs were used for preloading and wear compensation
Now, synthetic resin ball seats with elasticity and lubrication are widely used, which not only reduces the cost, but also improves the handling stability
In addition, the material and shape of the dust cover and the type of grease have been greatly improved
The grease nozzle has been eliminated and the maintenance free structure has been realized

 
The ball head pin is mainly composed of end cap, ball pin, ball seat and dust cover
The end cap is mostly made of steel plate stamping parts, which are mainly made of carbon steel, and some are also made of aluminum alloy or nodular cast iron

High machining accuracy is required for the ball pin surface
Alloy steel with good hardenability is mostly used
The surface of the ball pin matched with the metal ball needs high-frequency quenching and other surface hardening treatments to improve the wear resistance
At present, ball pins and non-metallic ball seats are mostly used to match, so only the ball pins need to be tempered
The diameter of the ball pin shall be selected according to the tensile strength, durability and other factors

 
The ball seat is made of case hardened steel, powder metallurgy, nylon, polyacetal resin, polyurethane and polyester elastomer
Because the material and shape of the ball socket have a great influence on the wear and fatigue life, molybdenum disulfide or oil is immersed in the material to improve the wear resistance
Reinforcing ribs or composite materials can also be added to the ball seat

 
The tightness of dust cover has a great influence on the wear and fatigue life of ball joint pin
Its materials are mostly polyurethane or neoprene with high temperature resistance, oil resistance and aging resistance
In addition, the deformation during its movement shall be considered in the design to prevent the dust from entering the ball joint pin from the mating moth after deformation
At the same time, the fitting accuracy of the dust cover and related parts also has a great impact on the sealing performance and service life
