ABSTRACT A bearing for a mill roll is forced to and held in the proper position on the neck of the roll by a clamp up device that fits around the roll neck between the bearing and a conventional split hinged ring which serves as a backing for the device. The clamp-up device in- cludes inner and outer rings which together form an an- nular fluid chamber, and when this chamber is pressurized, the outer ring extends, forcing the bearing to its proper position on the roll neck. Within the chamber, each ring is provided with ramps which align and come against each other when the outer ring is turned to the proper angular relationship with respect to the inner ring, and when the outer ring is so disposed it will remain axially extended to hold the bearing in its proper position on the roll neck during operation of the mill roll. A locking plate is provided to lock the rings against rotation relative to each other once they are in the proper angular re- lation. The clamp-up device is particularly useful in connection with bearings designed to fit tightly over tapered roll necks.
