Abstract: A bearing with an integral diverted lantern ring for installation into the seal cavity of a rotary mechanical device to provide a bearing surface and allow for flush fluid to engage the shaft closer to the motor end is provided. The bearing eliminates whip in a rotating shaft and is split to allow easy installation over an installed shaft. The bearing is substantially cylindrical with an inner bore closely approximating the outer diameter of the shaft. The diverted lantern ring includes an outer groove at the impeller end on the outer surface at a flush port and a groove on the inner surface at a location closer to the motor end. Flush fluid channels are provided between the outer groove and inner groove of the bearing. The purpose is to redirect the external flush from the impeller end on the OD to the motor end on the ID, thus repositioning the flush deposit on the sleeve, under the bearing. This allows the throttling characteristic of the close clearance bearing surface to increase.

Abstract: A seal-bearing assembly to be inserted into the seal cavity of a mechanical device to provide a seal and a bearing surface to eliminate whip in a rotating, reciprocal, or rotating and reciprocal cylindrical member. The seal-bearing assembly is particularly well suited for use in a reciprocal pump or a piston-driven valve, or between the steam lance and fixed steam tube in a sootblower. The assembly includes at least a pair of outer substantially rigid cylindrical bearings having an inner bore to be positioned over the cylindrical member and at least one complimentary flexible textile packing ring substantially comprised of carbon disposed between the two outer bearing members. In assemblies including an additional bearing, the additional bearing is surrounded by at least one flexible packing on each side. The inner bore of the bearing members provides a bearing surface for eliminating whip of the moving elements in the device.
