Center holes on roll journals often take a beating during the installation process in a mill or printing plant. Depending on the repair process, refurbished rolls can end up with journals that are misaligned with the center holes making future repairs problematic.  Finding the true centerline on a roll with a damaged or misaligned center hole can be very difficult and time-consuming.

The Live Chuck Mandrel from Riten Industries solves this problem by chucking on the bearing journals of the part. The design features a "quick-true" system which makes it easy to locate the roll on the machine's centerline through simple touch-off indication. Compared with live center-supported rolls, users report improved part quality and throughput increases up to 25 percent, according to the company's press release.

Typical models feature an extra heavy duty bearing assembly coupled with either a three-jaw scroll chuck or a four-jaw independent chuck.  Standard Morse tapers and chuck sizes from 6" to 18" are available. Other configurations can be custom engineered for unique applications. Live Chuck Mandrels, along with all other Riten workholding products, will be on display in Booth #W-1336 at IMTS 2010 in Chicago.
