Fine Lock (Rolling Type Core Chuck)
A new type of core chuck – clamps using only rotational force, no pressing force required.
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’ long-standing expertise in unwinding and rewinding technology, Fine Lock is built for durability and long service life.
