PNEUMATIC MECHANICAL SHAFT (Mechanical Expanding Shaft – Screw-Driven Type, developed by PNEUMATIC INDUSTRIES CO., LTD.)
Fast, precise, and damage-free gripping of paper, steel, and plastic cores. Custom-built to fit your machinery.
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.
