Round/square geometry for safety chucks

Boschert offers a new round/square seat geometry for its safety chucks, called the VT-7 style. The seat geometry is a square, triangle, or other geometry. This new seat geometry separates the load of the roll from the torque of the roll, offering the customer longer life for the roll shaft journal and for the seat of the safety chuck. Because the load of the roll is on the round portion of the seat, the bar rides in the bottom of the seat during operation. This means a smoother vibration-free run every time. The VT-7 is easily retrofitted by simply removing the existing Boschert VT insert and installing the VT-7 style. Turnaround time for this change is five minutes or less.
