What is Head?
Head can also be called bearing end cap, is used to close the top of the apparatus four, so that the inside and outside of the quality isolation components. According to the different appearance of the surface layer, the head can be divided into convex, who-type, flat-plate computer type and combination type.
Plate computer type and combination type, in which convex head can be divided into hemispherical type,Oval type, disk type and so on. Heads include the main types currently on the market and are used in aerospace, national defense, petrochemical and chemical industries.
