Ball Mill Trunnion Bearing Lube System

On a 11'-6" x 22'-0" Ball Mill, the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings, and high pressure oil for hydrostatic lift of the feed and discharge trunnions during start-up of the mill. System monitors including pressure switches and flow monitors are provided, along with temperature sensors that monitor ...

What are recirculating linear bearings?

Recirculation does present some challenges though. First, as the balls or rollers circulate through the bearing, they move from a non load-carrying zone (sometimes referred to as the return zone) to a load-carrying zone. This variation of the balls (or rollers) from a ...
