Lubrication and Seals
‘Directed Lubrication’ minimizes power loss and oil flow while keeping pad temperatures low. Oil flow is controlled by nozzles between each pad with the oil exits from each end of the bearing having only large clearance baffles.
While the standard system described above is ideal for the bearing itself, the machine location in which a bearing is installed sometimes requires restriction of the end flow, either at one or both sides.
Floating seals reduce the flow along the shaft to a minimum; if two floating seals are used, the main flow is directed through an orifice outlet usually at the bottom of the bearing.
Knife edge endplates, while less effective than floating seals, offer some control of end leakage.
