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.

Tidland’s Raptor Series torque chucks also offer unique ergonomic benefits to operators. 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. The toolless adapter allows users to switch core sizes in two steps, taking less than five seconds overall.
