The bearing members (22) are rotatably engaged in their apertures (24) by cooperating retaining portions (28,30,34) on the bearing holder (16) and bearing members (22). A method of making such a turntable element (10) with the bearing holder (16) and bearing members (22) formed as an integral body is also disclosed.
