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.
