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
WhatsApp: +86 18203695377The bearings in smaller mills may be grease lubricated, but oil lubrication is favored in large mills, via motordriven oil pumps. The effectiveness of normal lubrication protection is reduced when the mill is shut down for any length of time, and many mills are fitted with manually operated hydraulic starting lubricators, which force oil between the trunnion and trunnion bearing, preventing ...

If you look closely at them you will notice that they have holes in them. As the rings revolve with the bearing these holes pick up oil from the SUMP in the bearing base and carries it to the top of the bearing.
