Unlike any other bearing on the market, Kingsbury's CH Bearing System is a complete self-contained equalizing unit. The system eliminates the need for an electric motor/pump, emergency pump, accumulator, rundown tank, or other special arrangements for oil lubrication. No additional motor control system or any electric power is required to circulate the oil. And since no separate lube system is required, the cost savings is significant.
System lubrication is autonomous, provided by means of a viscosity pump driven by shaft rotation. This pump consists of the combination of the built-in mechanical oil circulator and the rotating collar, which draws oil up from the sump as soon as the shaft begins to rotate. As long as the shaft rotates, pumping action is achieved. No priming is necessary since the pump inlets are always submerged. Pumping action is bidirectional and automatically adjusts with shaft rotation. The pressure and flow generated by this pump force the oil out through passages in the housing to lubricate both thrust bearings and the internal journal bearing. The pressure in the thrust cavity then drives the hot oil through the oil cooler and then back into the oil sump. The fewer the restrictions in the system, the more the circulator can pump.
Sufficient flow and pressure are developed by this pump to send oil to a separate, remote journal bearing and — if required — additional equipment, for example, the system prime mover.
