The fixture, adapted to receive and contain the inner race member for grinding, is engageable with, and rotatable between, headstock and tailstock members of a grinding machine. In a preferred embodiment, the fixture incorporates a slide assembly which is reciprocated between two offset parallel centerlines during grinding of a race member contained within the fixture.
