Ball Mill Maintenance & Installation Procedure
Where "starting jacks" are provided for the trunnion bearings of the larger sized mills, they should be filled with the same oil that is used for the lubrication of the trunnion bearings. Before starting the mill they should be pumped so as to insure having an oil film between the journal and the bushing. Ball Mill Relining

What Is a Journal Bearing and Why Are They Important?
What Is a Journal Bearing. A journal bearing is one of the simplest types of bearing. A journal bearing is a bearing that allows a shaft to rotate freely within a supporting sleeve or shell. The part of the shaft which fits in the bearing is the journal, giving rise to the name. Unlike roller and ball bearings, journal bearings do not have …
