ABSTRACT:
An outer sleeve of a rotary table deck bushing has an axial passage extending therethrough and within which is disposed an inner core, which has an axial passage extending therethrough to receive a drill string of a drilling tool. The inner surface of the outer sleeve and the outer surface of the inner core have cooperating bearing races to form raceways within which are disposed ball bearings to rotatably support the inner core within the outer sleeve. Each of the raceways communicates with an access passage extending through the outer sleeve to enable ball bearings to be supplied to the raceway and removed therefrom. The outer sleeve supports a slidable key for blocking each of the access passages when the slidable key is in its blocking position. The slidable key is retained in its blocking position on the outer sleeve by a set screw.
