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

The Pneumatic Shaft is widely used in winding and unwinding operations. By simply inserting the shaft into a core and inflating with air, the internal rubber tube expands and projects the lugs, securely gripping the core. Pneumatic Industries’ shafts are renowned for their durability and trusted reliability. Key Features ・Easy Core Loading and Removal for Increased Efficiency 　Core loading and removal are streamlined by supplying and exhausting air. Positioning is simple and precise, ensuring effortless centering. ・High Precision and High Tension Capacity 　Designed to withstand high torque and high-speed rotation, preventing raw material misalignment and core slippage. ・Prevents Core Damage for Cost Savings 　Lugs apply pressure at multiple points along the core’s inner surface, minimizing damage and extending core life. Backed by decades of expertise in unwinding and rewinding technology, PNEUMATIC INDUSTRIES CO., LTD. delivers proven reliability and long service life.

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.

High strength and durability Proven in demanding fields such as aerospace and sports equipment, CFRP offers robustness, long service life, and maintenance-free operation. 3. Superior precision Reduced inertia (GD²) enables higher operating speeds with minimal deflection, preventing core slip and ensuring accurate winding. 4. Flexible options Available in pneumatic type for high workability or mechanical type for ultra-high precision with minimal runout. If you are looking for CFRP shafts, trust PNEUMATIC INDUSTRIES CO., LTD., where technology meets reliability. Contact us at: sales@pneumatic.co.jp

The characteristics of the leaf-type shaft are that, unlike a typical shaft where a long, slender rod called a "lug" expands and contracts to grip the core, a semi-circular plate called a "leaf" expands and contracts to hold the core. This results in a larger surface contact area compared to the lug, allowing for the gripping of thin-walled paper tubes without damaging the core. 1. Compatible with thin-walled paper tubes The leaf clamps the core with surface contact, ensuring reliable torque transmission. The leaf does not damage the core even with thin-walled paper tubes due to surface contact. 2. With the direct winding clamp function, the raw material can be clamped with one touch There is also a version with a direct winding clamp function that allows for one-touch clamping of the raw material. 3. You can choose the drive method. It can be manufactured in either air-operated or mechanical types.

The Air Shaft Adapter is designed to be mounted on an air shaft to change the core diameter it can grip. A common application is to attach the adapter to a 3-inch paper tube or plastic core shaft, enabling it to handle 6-inch paper tubes or plastic cores. This eliminates the need to manufacture a dedicated 6-inch shaft, making your existing shafts more versatile. Even if you typically use 3-inch cores but occasionally require 6-inch cores, the Air Shaft Adapter provides a practical and cost-effective solution. 　1）Compatible with 6-inch cores using your 3-inch shaft 　　・Much lighter and more economical compared to manufacturing a dedicated 6-inch shaft. 　　・Easier handling than a 6-inch shaft, improving work efficiency. 　2）Effective utilization of existing shafts 　　・Use your current shafts as they are—no additional processing required. 　　・Available for a wide range of core sizes, from 4 inches up to 12 inches.

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.

The PNEUMATIC SHAFT integrates two critical functions into a single design: 1.　Core clamping by expanding lugs, securing paper, plastic, or metal cores. 2.　Blade positioning for separator discs and slitter knives, with quick and precise adjustment. This dual capability greatly reduces setup time and simplifies changeovers. Because blade positions can be adjusted without replacing the shaft, integration with NC systems is straightforward, enabling efficient automation. Unlike conventional air or mechanical shafts that only clamp cores, this shaft also provides advanced blade fixing, significantly enhancing equipment productivity and value. Key Advantages ・Quick Position Adjustment Clamp and unclamp separator discs and slitter blades with ease, reducing downtime. ・Automation-Ready Blade positions can be adjusted without shaft replacement, supporting NC-based automation. ・Dual Functionality Combines reliable core clamping and precise blade positioning in one shaft, cutting setup time and maximizing efficiency.

The hanger type is an air shaft specialized for transporting roll-type materials. By simply inserting air into the core of the roll, the serrated lugs securely clamp the paper tube, making it easy and efficient to move the roll without gripping the outside, thus preventing damage to the wound product. 1. Easy handling of roll-type materials Just insert air into the core. Since it clamps from the inside, it is easy to retrieve products that are deep inside. 2. Highly effective in preventing product scratches There is no worry about damaging the product since it does not grip from the outside. The serrated lugs securely clamp the paper tube.

Our company manufactures and sells air shafts and air chucks that grip the core (core paper tube) during the expansion and contraction of rubber tubes. By utilizing the property of rubber balloons that expand when compressed air is added and contract when the air is released, we can easily and securely fix the core by moving the claws, called lugs, that are incorporated into the air shaft and air chuck. In addition to air-operated systems, we have also responded to customer needs with various mechanisms, including mechanical (screw-driven) and high-precision cylinder types, as well as cam systems. By leveraging these mechanisms, we can not only secure the core but also use them for applying seals to products, as fixtures for lathes and machining processes, and more recently, as shafts for tool mounting, where they are used for clamping after NC control has positioned the tools. If you have any inquiries about potential uses for these systems, please feel free to reach out to us if you think it could lead to improvements for your company.
