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.

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.

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 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.

A mechanical shaft, unlike an air shaft that uses rubber tubes to extend the lugs, raises the lugs by rotating the screw of the central axis, ensuring excellent concentricity between the paper tube and the shaft, thereby eliminating core runout! This is a pneumatic mechanical shaft that reliably performs high-speed feeding and winding operations. 1. Suitable for high-precision feeding and winding operations The lugs expand and contract with the rotation of the central axis screw, maintaining constant concentricity with the shaft in a stepless manner. 2. Easy core attachment and detachment with simple position adjustment Can be attached and detached with one touch using an impact wrench (manual operation is also possible). Positioning the core is easy. 3. Lightweight, robust structure that can be customized Materials such as duralumin and steel can be selected according to your requirements. We can accommodate specifications such as diameter, length, and shaft shape according to your needs.
