A core assembly is disclosed to form a hub for a single bearing skate wheel. The core assembly includes a unitary core member having a radially inner portion defining an axial opening extending therethrough. An annular shoulder surrounds the axial opening and defines a socket which is sized and shaped to receive a single self-contained bearing 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 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.

A core assembly to form a hub for a single bearing skate wheel, said core assembly including: a core member having a body member having an axis and a radially inner cylindrical portion defining an axial opening extending through said body member to define a first end opening and a second end opening

A core assembly to form a hub for a single bearing skate wheel, said core assembly including: a core member having a body member having an axis and a radially inner cylindrical portion defining an axial opening extending through said body member to define a first end opening and a second end opening, said core member having a center line which is transverse to said axial opening and intermediate said first end opening and said second end opening; an annular shoulder within said axial opening and defining a socket which is open to said first end opening and is sized and shaped to receive a single self contained bearing assembly having a center line, said shoulder being positioned to align the center line of such a single self contained bearing assembly with said center line of said core member when such a single self contained bearing assembly is disposed within said socket; bearing retainer means for removable connection at said first end opening of said core member for removably securing such a single self contained bearing assembly within said socket; said bearing retainer means including a pressure ring having an upper surface, a lower surface adapted to maintain a single self contained bearing assembly within said socket with the center line of such a single self contained bearing assembly aligned with the center line of said core member when disposed in said socket, an outer circumferential edge, and a plurality of annually spaced elongated ears having an upper surface and extending from said circumferential edge; and locking means disposed axially outwardly of said socket at said first end opening of said core member for securely locking said bearing retainer means in place within said core assembly, said locking means including a plurality of annular lips spaced radially inwardly from the body of said core member to form a plurality of annularly spaced slots sized and shaped to receive said ears as said ring is rotated about the axis of said core member, said locking means further including pressure increasing means in the form of a button disposed inwardly of each said lip surface adapted to engage the upper surface of said ears as said ring is rotated to increase axial pressure of said pressure ring against such a single self contained bearing assembly as said ring is rotated.
