Manufacturer pneumatic expanding air shaft
The inflating operation time of the air expanding shaft is short. It takes only 2 seconds to separate and place the inflatable shaft from the paper tube to complete the inflation and deflation, and it does not need to separate any parts at the end of the shaft to tightly engage with the paper tube; The paper tube is placed simply: with the action of inflation and deflation, it can move and fix any position of the paper tube on the shaft surface.

Large bearing capacity of the inflatable bearing: the size of the shaft diameter can be determined according to the actual needs of customers, and high strength steel can be used to increase the bearing capacity. High economic efficiency: the shaft is designed for special functions, which can be used for all kinds of paper tubes that are thick, thin, wide and narrow.
Introduction:
The contraction part of the plate type inflatable shaft is the plate, usually the expansion height can reach 4mm to 5mm, for example, the diameter before contraction is 74mm to 75mm, and the diameter after contraction can reach 78mm to 79m. The special contraction height is separately required and determined by the customer. The 3 inch plate type inflatable shaft usually uses a coil with an inner diameter of 76mm. The plate type inflatable shaft shrinks from the entire plate, the fulcrums are evenly dispersed, and the force is average. It can be used for machinery with higher winding precision or winding Light items.
