The cantilever type is a cantilever air shaft or mechanical shaft. Compared to the double-supported type, it has some disadvantages in rigidity and deflection, but it offers advantages that the double-supported type does not, such as ease of workpiece attachment and detachment, excellent workability, and ease of automation. 1. Extremely easy workpiece (core roll) extraction Since it is a cantilever type, extracting the workpiece is extremely easy. This also improves work efficiency. 2. Possible to fully automate The shaft extraction work is unnecessary as the workpiece can be pulled out directly. Automation is easy because a shaft attachment and detachment mechanism is not required. 3. Choice between air type and mechanical type Air type offers excellent cost performance. Mechanical type excels in runout accuracy. We propose the optimal solution tailored to your specifications.

At Pneumatic Industry, we leverage our experience as an air shaft manufacturer to offer consultations for the repair and maintenance of various air shafts. While it may be difficult to repair depending on the manufacturer, structure, and condition, there are cases where we can handle products from other manufacturers as well. We will first check the condition and specifications of the actual item and then propose whether repair is possible and the appropriate methods. ■ Consultation Examples - Air leaks - Punctures - Not expanding - Weak expansion - Core (paper tube/plastic tube) slipping - Vibration during rotation - Increased core wobble - Safety inspection (wanting to check the condition after many years of use) - Requesting regular maintenance Please feel free to consult with us.

The air shaft applies an expansion holding mechanism used for holding paper tubes and unwind/reel cores, and can also be utilized for positioning applications. By setting holders, collars, spacers, jigs, and other components with an inner diameter on the shaft and expanding the outer circumference through air supply, it contributes to the efficiency of attachment, replacement, and setup by holding multiple parts collectively from the inner diameter side. We can propose solutions for applications where parts need to be positioned and fixed on the shaft, such as aligning slitter blade holders, inspection jigs, and interchangeable units. It can be used not only for manual setup changes but also as a holding mechanism during automation equipment and robot transport.
