A blind hole bearing puller of general utility is disclosed. A bearing puller extractor tool 2, as shown in the figure, enables pulling of bearings out of blind holes 3 in driver hubs 1, for example, of magnetic roll racks as found in certain electrophotographic development subsystems. The tool is operated by inserting the puller 2 into the blind hole 3 residing in hub 1. Next, a threaded T-handle 4 is inserted to engage the puller 2 which in turn grips the bearing housing 5 by outwardly spreading the jaws 6 of the puller 2. Bearing housings may be removed from driver hubs quickly and without damaging the tool or bearing components.
