PNEUMATIC INDUSTRIES CO., LTD. Company Overview

Please feel free to consult us about any issues or discomforts such as air leaks, core slippage, difficulty in removing the core, weak bulging, or increased core wobble.

While using air shafts and core chucks, have you experienced any unclear issues or discomfort such as "the core (paper tube/plastic tube) is slipping more than before," "the core has become difficult to remove," "the bulge is weak," "it feels like there is air leakage," "the vibration during rotation has increased," or "I am concerned about the core and shaft misalignment"? At Pneumatic Industry, we offer consultations regarding the condition of core holding components used around winding and unwinding devices, such as air shafts, mechanical shafts, air chucks, and mechanical chucks. Even if the drawings or model numbers are unknown, we may be able to estimate the cause and solutions based on the symptoms and photos provided. Please feel free to reach out to us for assistance.

An expansion retention mechanism for the air shaft that securely holds the holder, collar, spacer, and jig together on the shaft.

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.
