Torque Activated Core Chucks

Montalvo’s flange-mounted steel GR-Series torque-activated core chucks incorporate leaves that self-expand through reel rotation combined with web tension. They are ideal for high weight, speed, and tension unwind or rewind applications (i.e., sheeting, paper, laminating, etc.) for precise, consistent tension control from full roll to the core. The GR Series is also available in a Step Design or with bolt-on Adapters when working with multiple core sizes from 3″ to 16″.
