●Introduce the latest stable airend with high efficiency and durability. It is famous for 0 fault and the least maintenance cost.
●The air-inlet port uses the ball bearing which bears averaged force and has high stability
●The air outlet port uses back to back duplex taper roller bearing, which suffers thrust load by line contact and offsets radial force and axial force
●Due to the unique design of the oil tank, it avoided dry friction of the bearing and prolonged its service life. Without this structure, the dry friction would take about one hour each year which is deadly damage to bearing.
