Abstract

A coupler is for selectively coupling a first bearing ring with a first backing ring or a second bearing ring with a second backing ring and includes a flexible annular body disposeable simultaneously within the first bearing ring and first backing ring or within the second bearing ring and second backing ring. A first bearing projection and a first backing ring projection extend radially from a first circumferential surface and are axially spaced apart and a second bearing projection and a second backing ring projection extend radially from a second circumferential surface and are axially spaced apart. The body is invertible between a first orientation in which the first bearing ring and backing ring projections are disposeable within the first bearing and backing ring openings and a second orientation in which the second bearing ring and backing ring projections are disposeable within the second bearing and backing ring openings.
