A core assembly is disclosed to form a hub (12) for a single bearing skate wheel (10). The core assembly includes a unitary core member (14) having a radially inner portion defining an axial opening (24) extending therethrough. An annular shoulder (58) surrounds the axial opening and defines a socket which is sized and shaped to receive a single selfcontained bearing (34) therein. The socket is positioned to align the center line of the bearing with the center line of the core member when the bearing is disposed within the socket. A bearing retainer member (38) is also provided for removably securing the bearing within the socket. Finally, a member is disposed axially outwardly of the socket for securely locking the retainer mechanism in place within the core assembly.
