A parts suction head having a non-contact sealing head is disclosed. The head includes: a moving block having first air passages on its upper surface and having a first hollow unit in a longitudinal direction; a spacer having second air passage connected to the first air passage for air flow, and having a second hollow unit in a longitudinal direction; a rotation shaft being inserted into the second hollow unit of the spacer at interval and having third air passage connected to the second air passage for air flow, and having a third hollow unit in a longitudinal direction; and flanges for sealing up an interval between the spacer and the rotation shaft. The rotation shaft is installed in the moving block in a non-contact type by using the spacer to prevent the non-linear frictional force.
