The gear and bearing puller is designed to remove both gears and bearings from a shaft. It uses arms that grip behind the gear teeth or around the outer race of a bearing, and a central screw that you tighten to apply an axial pulling force. As the screw turns, the force is transmitted through the arms to pull the gear or bearing straight off the shaft without twisting or marring the shaft shoulder. This dual capability—removing gears and removing bearings—is why this tool is the right fit. Other pullers target different tasks: a universal gear puller is adaptable for various gears but not specifically optimized for bearings; a push and pull set handles pressing in or pulling out items but isn’t the go-to for extracting gears or bearings from shafts; a cotter pin puller is for removing cotter pins, not gears or bearings.
