The ordering guide:
Users need to specify when customizing the inflatable shaft type : appearance size, valve position and type such as the pointed air nozzle or the flat air nozzle, along with the specified external diameter of the thread and the pitch of the teeth. or the default type is a pointed air nozzle. Mark important shaft head size tolerance.If the axial inlet, gas mouth shaft head when installation need more than 35 mm diameter.All inflatable axis are required to issue a formal drawings, the two sides confirmed rear can production.
