1. A rolling element bearing retention arrangement comprising:
an outer ring including:
a first inner radial surface having an outer rolling element raceway;
an outer radial surface having a first circumferential groove configured with a first cavity;
a housing including:
a coefficient of thermal expansion greater than a coefficient of thermal expansion of the outer ring;
a bore with a second inner radial surface for receiving the outer ring, the second inner radial surface having a second circumferential groove configured with a second cavity; and,
a retaining ring received partially by the first and second circumferential grooves, the retaining ring including:
a radially inward directed protrusion at a first end engaged with the first cavity; and
a radially outward directed protrusion at a second end engaged with the second cavity; and
in a first retained state at a first temperature:
the outer radial surface is axially and rotationally retained by the second inner radial surface by an interference fit; and,
in a second retained state at a second temperature greater than the first temperature:
the outer radial surface is axially and rotationally retained by the retaining ring, the first and second circumferential grooves, and the first and second cavities; and, the outer radial surface is separated from the second inner radial surface.
