PNEUMATIC INDUSTRIES CO., LTD. Product Lineup

The Pneumatic Air Chuck (Shaftless Air Core Chuck – End-Grip Type) eliminates the need for inserting and removing a full-length shaft, making it ideal for shaftless machines. By gripping the core ID at both ends, it prevents the end-face damage often caused by tapered cones while ensuring secure torque transmission for heavy-duty winding and unwinding. Key Features ・Compact Body, Strong Grip 　A compact cylinder diameter delivers high clamping force, and V-groove machining ensures reliable torque transmission even under heavy loads. No side pressure is required. ・Lightweight, Excellent Tension Control 　Its small diameter minimizes rotational inertia, making it ideal for applications requiring low or precise tension control. ・Easy Automation 　The shaftless structure simplifies automated roll loading and removal. One-touch air charging makes clamping easy, with an air-injection option also available. Backed by decades of experience in unwinding and rewinding technology, PNEUMATIC INDUSTRIES CO., LTD. delivers proven reliability and long service life.

The MC-3 is a shaftless, lug-type mechanical chuck that grips from inside both core ends. It prevents end-face damage common with taper cones, eliminates air-shaft insertion and removal steps, and supports long-term reuse of paper tubes, contributing to a lower total cost of ownership. It also accommodates deformation at the core opening. Key Features and Benefits 　1. Easy retrofit, higher throughput 　　• Simple mechanism for quick changeovers. 　　• Secure, non-slip holding ensures complete core fixation and stable winding. 　2. Broad core compatibility 　　• Large lug expansion range covers wide ID tolerance. 　　• Grip point set back from the end face for reliable clamping, even with end fittings. 　3. Automation-ready, high-quality winding 　　• Shaftless, lightweight, compact body simplifies automated attach/detach. 　　• Surface contact rather than cone line contact improves torque transmission. 　　• Minimal runout supports high-precision, high-speed winding and unwinding. Backed by decades of experience in unwinding and rewinding technology, PNEUMATIC INDUSTRIES CO., LTD. delivers proven reliability and long service life.

The Pneumatic Mechanical Chuck eliminates the need for inserting and removing full-length shafts, while also preventing the end-face damage often caused by tapered cones. By gripping the core ID at both ends, it extends core reusability and supports stable, cost-effective operation. The MH-3 Type incorporates a leaf-type design that provides an exceptionally wide contact area, delivering secure torque transmission and contributing to high-quality, consistent winding. Key Features ・Reliable torque transmission with wide-area contact 　The leaf design offers greater surface contact than the MC-3 Type, preventing paper tube deformation and preserving product quality. ・Compatible with various core sizes 　Suitable for core inner diameters starting from 2 inches. ・Automation-ready 　A fixed end cap prevents sliding, making core insertion smoother and facilitating automated handling. Backed by decades of experience in unwinding and rewinding technology, PNEUMATIC INDUSTRIES CO., LTD. delivers proven reliability and long service life.

Unlike air chucks or conventional mechanical chucks, Fine Lock clamps the core using only rotational force. It combines high concentricity with an ultra-compact, lightweight design and delivers outstanding performance in high-speed winding and unwinding operations. Key Features ・No Pressing Force Required; Supports Heavy Loads 　It clamps solely by rotational force. The compact body is engineered to support heavy loads. ・Ultra-lightweight and Compact 　Its minimal mass reduces rotational inertia (GD²), enabling ultra-high-speed rotation. The non-pressing mechanism avoids power loss and allows precise torque control. ・Always Concentric with the Winding Shaft 　Each lug (claw) deploys in sync with rotation to maintain concentricity. It clamps in both clockwise and counterclockwise directions, enabling both forward and reverse winding. Backed by PNEUMATIC INDUSTRIES CO., LTD.’s long-standing expertise in unwinding and rewinding technology, Fine Lock is built for durability and long service life.
