Mechanical chucks

Product catalog summary

Introduction
Mechanical chucks are essential in shaftless applications for controlling reels during unwinding and rewinding processes. They are particularly useful when reels are too heavy for expanding shafts, machines are wide, or reel core diameters vary.

Specifications
Re chucks are made from durable materials, ensuring high performance, longevity, and minimal maintenance. They are available in various types, including classic TM/A - TM/B axial thrust chucks, Rotogrip rotating chucks, and pneumatic-mechanical chucks (MX16.3 - Pneumogrip), in both mono and double diameter versions.

Rotogrip Rotation Chucks
Rotogrip chucks use torque from braking force and web tension to expand sector elements, automatically centering the roll core. They offer flexibility with different dimensions and are suitable for cores from 3” to 12”. These chucks are ideal for large, heavy reels, such as those used in corrugated cardboard production.

TM Axial Thrust Mechanical Chucks
TM chucks use a spring system to expand keys for reel grip. They offer a good quality-to-price ratio and are available in mono and double diameter versions, supporting loads up to 300,000 N. Special versions include central bore for photoelectric sensor centering and ejection flange.

Pneumo-Mechanical Chucks
The MX 16.3 and Pneumogrip chucks use air pressure to expand keys for secure reel fixing. The MX 16.3 is compact and robust, suitable for converting sectors, and supports reels up to 20,000 N. Pneumogrip chucks are flexible, supporting cores from 70 mm to 12” and loads up to 40,000 N, making them suitable for industries using large reels.

Technical Data
Technical drawings and data tables provide detailed specifications for each chuck type, including dimensions, load capacities, and torque transmission capabilities. These details are crucial for selecting the appropriate chuck for specific applications.

Conclusion
Re chucks offer a comprehensive solution for automated machining processes, optimizing production while reducing costs and errors. For precise product selection, consulting with sales engineers is recommended.

Mechanical chucks are used in shaftless applications to guarantee a perfect control on the reel in unwinding and rewinding stations. The mechanical chucks are usually used when: • the reel is too heavy to be supported by an expanding shaft, • the machine is very wide, • the diameter of the reel core is often different. Re chucks are designed and produced with sturdy materials and comply with high quality standards to ensure you elevated performaces, long-life span and almost zero maintenance costs also in difficult working conditions. We offer our clients a wide range of chucks: • classic TM/A...
