Kingsbury's CH Bearing System consists of a NDE unit featuring a flange-mounted housing with an equalized thrust bearing and a journal bearing shell, and a DE unit without a thrust bearing. The CH System is unique because it is completely self-contained, thereby eliminating the need for an external lube skid, emergency pump, accumulator, rundown tank or other special arrangements for oil lubrication.
Since no separate lubrication system is required, the cost savings are significant. Lubrication of the bearings is autonomous, as the NDE unit acts as a viscosity pump driven by shaft rotation. The system's oil circulator, working in tandem with the rotating collar, draws oil up from the sump as soon as the pump is switched on and therefore assures lubrication whenever the machine is in operation.
