A sliding chuck allows the shaft to be locked in position while transferring torque at High RPM. Dual holding mechanism for Square for Torque transferring & Round for load Handling and designed for higher speed applications.
It is automatic locking upon Rotation and offers precise concentricity than the standard square type safety chuck. It is better concentricity means less noise & vibration during the run, and greater life and very little damage to shaft journals.
A chuck is a specialized type of clamp used to hold an object with radial symmetry, especially a cylinder. In a drill, a mill and a transmission, a chuck holds the rotating tool; in a lathe, it holds the rotating workpiece.
Chucks commonly use jaws to hold the tool or workpiece. The jaws (sometimes called dogs) are typically arranged in a radially symmetrical pattern like the points of a star. Jawed chucks may require a wrench-like device called a chuck key to be tightened or loosened, but other jawed chucks may be tightened or loosened by hand force alone, offering convenience at the expense of gripping force.
Chucks on some lathes have jaws that move independently, allowing them to hold irregularly shaped objects. More complex designs might include specially shaped jaws, greater numbers of jaws, or quick-release mechanisms.
