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.

At Pneumatic Industry, we develop and manufacture air shafts, air chucks, and related devices that use the expansion and contraction of rubber tubes to grip and release cores (paper tubes). Just like a balloon inflates and deflates with air pressure, our mechanism drives built-in lugs that expand outward to clamp and inward to release — enabling secure, repeatable attachment and detachment of the core. We offer not only air-operated systems but also mechanical (screw-driven), cam, and high-precision cylinder types, designed to match each customer’s specific needs. These core technologies are already in use far beyond conventional winding applications: 　• as fixtures and positioning tools in machining and lathe operations, 　•for labeling or seal attachment systems, 　•as tool-mounting shafts in NC-controlled equipment. If your process requires gripping, expanding, or locking — our technology might be the key. Share your idea with us, and let’s explore what’s possible together. PNEUMATIC INDUSTRIES CO., LTD.

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.

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.
