A bushing for retaining and supporting at least one tool, spindle or the like includes at least two component parts which are constructed to together define therebetween an insertion seat for receiving a particularly tool, spindle or the like. The parts are adjustably movable with respect to each other between a plurality of differently spaced positions, to thereby adjust the size of the insertion seat as a function of the size of the particular tool, spindle or the like to be received therein. The parts each have retaining devices for matingly engaging each other in each of the plurality of positions, and for thereby fixing the relative spacing between the parts and the size of the insertion seat at each of the plurality of positions. |
