Abstract

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.

Bearing housings may be removed from driver hubs quickly and without damaging the tool or bearing components.

A similar, but mechanically distinct bearing puller tool is commercially available as CG-40-C from Snap-On@ Tools Corporation.
