摘要
Rolling mill bearings incorporate bearing bushings (20) with pluralities of hydrostatic pad recesses (30 40) that are preferably in conjunction hydrodynamic bearings also formed within the bushing. Each recess (30 40) has an isolated lubricant passage (136 146) that is adapted for coupling to a separate isolated source of pressurized lubricant (50). In some embodiments herein the isolated pressurized lubricant source is supplied by a dedicated outlet of a pressure pump. In this manner each hydrostatic pad recess has a dedicated pressurized lubricant supply that is not interrupted by loss of lubricant pressure events in other bearing pads or elsewhere within the rolling mill lubrication system.
