ABSTRACT

A separator is provided for a ball bearing including inner and outer rings and
a plurality of balls disposed between the inner and outer rings. The separator
includes an annular body having a centerline, opposing first and second axial
ends spaced apart along the centerline, an inner circumferential surface
defining a central pocket sized to receive one of the plurality of balls and
an outer circumferential surface defining an outer perimeter. A plurality of
inner axial channels extend radially outwardly from the inner circumferential
surface and a plurality of outer axial channels extend radially inwardly from
the outer circumferential surface, each inner axial channel and each outer
axial channel being configured to contain lubricant. Preferably, both the
inner and outer axial channels are spaced circumferentially about the
centerline and each channel extends entirely axially between the first and
second axial ends of the annular body.
