A compressor includes a shell, a motor assembly, a driveshaft, and a bearing assembly. The bearing assembly is disposed within the shell and supports the driveshaft for rotation. The bearing assembly includes a bracket, a hub, and a bushing. The bracket is coupled to the shell and includes an aperture. The hub is disposed within the aperture and defines a bore having a radially inwardly extending lip. The bushing includes a proximal portion and a distal portion. The distal portion of the bushing includes a plurality of radially extending engagement features. The distal portion of the bushing is disposed within the bore of the hub such that the engagement features engage the lip of the hub. 1. A compressor comprising:a shell;a compression mechanism disposed within the shella motor assembly disposed within the shell;a driveshaft drivingly engaged with the motor and the compression mechanism for rotation about an axis, the driveshaft extending from a proximal end to a distal end, the distal end having an axially extending passage; a bracket coupled to the shell and having an aperture;', 'a hub disposed within the aperture and extending from a proximal end to a distal end, the hub defining a bore extending from the proximal end of the hub to the distal end of the hub, the bore including a proximal portion defining a first diameter, a distal portion defining a second diameter that is greater than the first diameter, and a radially inwardly extending lip defining a third diameter that is less than the first and second diameters; and', 'a bushing having a proximal portion and a distal portion, the distal portion of the bushing having a plurality of radially extending engagement features, the proximal portion of the bushing disposed within the distal portion of the bore, the distal portion of the bushing disposed within the distal portion of the bore such that the engagement features engage the lip of the hub., 'a bearing assembly disposed within the shell and supporting ...

A bearing housing may include a body portion, a hub, and a thrust bearing. The body portion may include a radially inwardly facing first annular surface. A structure may extend radially outward from the body portion. The hub may extend axially from the body portion and may include a radially inwardly facing second annular surface adapted to rotatably support a shaft. The thrust bearing may extend axially from the body portion and may include an outer surface, a thrust surface, an inner surface, and an undercut feature formed in one of the inner and outer surfaces. The undercut feature may define a cantilevered portion of the thrust bearing. 1. A thrust bearing for a compressor having first and second working members , the thrust bearing comprising:an axially facing thrust surface configured to support one of the first and second working members;a first surface adjacent said thrust surface;a second surface adjacent said thrust surface;an annular undercut feature formed in only one of said first and second surfaces, said one of said first and second surfaces including a first radially facing portion disposed axially between said thrust surface and a first axial end of said undercut feature and a second radially facing portion disposed adjacent a second axial end of said undercut feature, said second radially facing portion being spaced apart from a drive shaft bearing.2. The thrust bearing of claim 1 , wherein said first and second surfaces are annular surfaces.3. The thrust bearing of claim 1 , wherein said undercut feature is formed in said first surface claim 1 , and wherein said first surface is disposed radially inward relative to said second surface.4. The thrust bearing of claim 1 , wherein said undercut feature includes an axially extending surface that is substantially parallel to and coaxial with said first and second surfaces.5. The thrust bearing of claim 1 , wherein said undercut feature includes a V-shaped cross section.6. The thrust bearing of claim 1 , ...

A compressor includes a shell, a bearing housing, an orbiting scroll, a non-orbiting scroll and a spacer. The bearing housing includes a central body and a plurality of arms extending radially outwardly from the central body. Each of the arms has a first aperture. The non-orbiting scroll is meshingly engaged with the orbiting scroll and includes a plurality of second apertures. Each second aperture receives a bushing defining a first longitudinal axis and a fastener defining a second longitudinal axis. The fastener extends through the bushing and into a corresponding one of the first apertures in the bearing housing. The spacer is disposed between the bushing and the fastener of each second aperture and is configured to engage one of the bushing and the fastener to restrict radial misalignment between the first longitudinal axis of the bushing and the second longitudinal axis of the fastener. 1. A compressor comprising:a shell;a bearing housing supported within the shell, the bearing housing including a central body and a plurality of arms extending radially outwardly from the central body, each of the arms having a first aperture;an orbiting scroll supported on the bearing housing;a non-orbiting scroll meshingly engaged with the orbiting scroll and including a plurality of second apertures, each second aperture receiving a bushing defining a first longitudinal axis and a fastener defining a second longitudinal axis, the fastener extending through the bushing and into a corresponding one of the first apertures in the bearing housing to rotatably secure the non-orbiting scroll relative to the bearing housing; anda spacer disposed between the bushing and the fastener of each second aperture and configured to engage one of the bushing and the fastener to restrict radial misalignment between the first longitudinal axis of the bushing and the second longitudinal axis of the fastener.2.
