Cores, Shafts, and Chucks in a Digital World

This style of replaceable insert is easily retrofitted into existing Boschert safety chucks that have VT inserts by simply unbolting the existing insert and installing the new round/square style. The VT-7's highly efficient design provides longer life between roll shaft journal changes and replaceable insert changes, more precise quality control of the web during the life of the insert, and fewer quality problems associated with high-speed runs.
