Tidland Raptor Series Torque Chucks

Tidland’s shaftless Chucks are ideal for continuous-duty shaftless applications in corrugating, sheeting, paper finishing or laminating. The unique design is extremely robust, easy to maintain and core-friendly. Ease of removal and insertion improve overall throughput while reducing waste associated with jammed cores.

Routine maintenance and core size changes can be made without removing the entire chuck from the machine, reducing downtime and the risk of injury due to heavy lifting.
