Tight tolerances between the roll shaft journal and the pocket of the Safety Chuck make for smooth operation. Tighter tolerances result in less movement in the pocket of the Safety Chuck. Reduction of movement results in greater life of those parts and less stress to the operation quality control sensors.

The triangular shape of the VT-6 provides for self-centering loading. The design is wider at the top allowing faster, easier loading and unloading. This creates faster turnaround and greater confidence for the operator in his equipment.

This triangular shape only allows movement insider the pocket two times per revolution instead of four times per revolution with a square shape. A roll shaft journal falls inside the pocket every revolution, that distance which is the tolerance. With less movement in the pocket, you get greater life for your roll shaft journal and greater life for the pocket of the Safety Chuck. The aggressive action between the journal and the pocket is not as severe because of the tight fit! Easier loading... smoother operation... get the full value of the Boschert VT-6 Safety Chuck.
