Kingsbury combined flange-mounted, horizontal equalizing thrust bearings and journal bearings with a remote journal bearing, and a self-contained lubrication system to create the CH Bearing System.

The CH System is unique because it is completely self-contained and equalizing. It eliminates the need for an electric motor/pump, emergency pump, accumulator, rundown tank or other special arrangements for oil lubrication.

Since no separate lubrication system is required, the cost savings are significant. System lubrication is autonomous, provided by a viscosity pump driven by shaft rotation. This pump consists of the combination of a built-in mechanical oil circulator and a rotating collar, which draws oil up from the sump as soon as the shaft begins to rotate.

The self-contained CH System is economical for industrial pump applications because it:

• Eliminates the need for an oil pump
• Does not require a separate lubrication system
• Provides lubrication for other bearings in pump system
• Simplifies engineering and maintenance
• Uses fresh water or sea water for cooling
