A journal bearing having a working surface for contacting a shaft, and channels provided on the working surface and being configured to collect lubricant and redirect lubricant across the bearing working surface. A method for lubricating a bearing assembly is provided where lubricant is delivered to the working surface of the bearing, the lubricant is collected on the surface and directed to areas of the bearing surface which are in need of lubricant to provide an even coverage of lubrication across a bearing working surface.

A thrust bearing for use with a shaft having a collar mounted thereon, comprises a base ring, a series of thrust bearing shoes positioned on the base ring, each shoe having a leading edge connected to a trailing edge by an inner diameter edge and an outer diameter edge, each thrust bearing shoe having a working face with a bearing liner on its surface, a shoe pivot member on each shoe allowing the shoe to pivot in any direction, an oil distribution groove formed in the working face of each shoe near the leading edge of each shoe and extending radially for substantially the entire distance between the inner and outer diameter edges of each shoe, each oil distribution groove having an inner end and an outer end connected by a leading edge and a trailing edge, an oil feed line leading to each oil distribution groove for feeding oil to each oil distribution groove, and a recess formed in the working face of each shoe commencing at the trailing edge of the oil distribution groove and extending rearwardly therefrom to develop hydrodynamic film pressure on the leading edge of each shoe to ensure that each shoe tilts properly at light loads.

A thrust bearing for use with a shaft having a collar mounted the shaft and rotatable therewith has a base ring , a series of shoes positioned on the base ring , and a compressible resilient spacing member positioned between the base ring and a housing for the thrust bearing. The spacing member supports the thrust bearing when the shaft is rotating during no-load operating conditions, as well as dampens the forces placed on the thrust bearing by the shaft when the shaft is rotating during no-load conditions. The spacing member is sufficiently stiff that it supports the thrust bearing when the shaft is rotating under no-load conditions, but is sufficiently compressible to be compressed to the extent that the gap between the base ring and the housing is eliminated due to the forces placed on the thrust bearing by the shaft bringing the base ring into contact with the housing during normal load operating conditions.
