Dougherty, John, Morgoil bearings used in rolling mills, thesis, Wollongong University College, University of Wollongong, 1968. http://ro.uow.edu.au/theses/2978
This subject is introduced with a description of the function of the bearings in rolling mills and the requirements of the bearings.
A description of the bearing parts is given in the next section. The next section describes the steps in the assembly of the bearing parts followed by a section on the preparation of the roll and the assembly of the bearing to the roll.
A section on lubrication of the bearings follows. It deals with the oil requirements and describes the action of the components in a typical lubricating system. The method of calibrating the oil flow to the bearing is also described.
The next section discusses the maintenance requirements of the bearings. This includes the responsibilities of both the mill and shop personnel in relation to the life of the bearings.
Some of the outstanding features found in the design of the modern bearing is given in the next section. This includes the sealing arrangement, the quick change assembly and hydrostatic lubrication.
The effect of the oil film in relation to mill performance and gauge control is discussed in the next section.
The last section involves the testing of bearings in relation to seal wear, position of oil inlets and bearing clearance. The results of some of these tests is given.
