START—
A bearing separator and puller set clamps split jaws behind the part, then a yoke and forcing screw pull it straight off the shaft.
For the full breakdown, see our best Bearing Separator And Puller Set guide.
A press-fit bearing rarely slides off a shaft by hand, and a conventional three-jaw puller often slips because it can’t get a grip behind the part. Knowing how to use bearing separator and puller set tools stops that problem: the split jaws lock behind the bearing, and the yoke-and-screw assembly pushes against the shaft center so the pulling force stays straight and controlled.
The routine below follows the factory manuals for common kits, including Harbor Freight’s Pittsburgh set and Eastwood’s 12-piece splitter/puller kit.
What a Bearing Separator and Puller Set Does
A bearing separator and puller set turns wrench force into a straight, even pull instead of a prying action. The core parts are the same across most kits: split separator jaws that clamp around the shaft behind the component, a yoke that bridges the jaws, extension screws for recessed work, and a forcing screw that turns through the center of the yoke.
