PNEUMATIC INDUSTRIES CO., LTD. List of Products and Services

The PNEUMATIC MECHANICAL SHAFT eliminates core runout through a screw-expansion mechanism, not air pressure. Unlike air shafts that rely on rubber tubes, its lugs expand by rotating the central screw, ensuring perfect concentricity between the core and the shaft. This delivers stable and reliable performance in today’s high-speed unwinding and winding operations. Key Advantages 1. Eliminates Core Runout 　Screw-driven lugs maintain perfect concentricity between the core and the shaft, preventing wobble even at high speeds. 2. Protects Core Interior 　Multi-point lug support minimizes damage to the inner surface of paper, steel, and plastic cores. 3. Quick & Easy Operation　 　One-touch core mounting and removal with an impact wrench, with manual operation also available. 4. Lightweight, Strong, and Customizable 　Available in high-strength materials such as duralumin or steel. 　Shaft diameter, length, and shape can be tailored to customer requirements.

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.
