The bearing puller is a device that takes out the inner bearing from the bearing seat. It is an internal bearing puller that includes a mounting plate, tension bolts, and threaded bolts; There are no less than two tension bolts, each with a claw at the bottom that can hang the bottom of the built-in bearing. A fastening nut is installed on each tension bolt, and there is no less than one long hole in the middle of the installation plate. The width of the long hole is greater than the diameter of the tension bolt. The lower end of each tension bolt passes through the long hole and extends below the installation plate, and the fastening nut can be clamped on the installation plate at the long hole; There are no less than two positioning nuts fixed on the installation plate outside the long hole.


Product Advantage
