Bearing puller is a device that takes out the inner bearing from the bearing housing, which is a kind of internal bearing puller, which includes mounting plates, tension bolts and thread bolts; There are no less than two tensile bolts, the bottom of each tensile bolt has a pull claw that can hang the bottom of the inner bearing, a fastening nut is installed on each tensile bolt, there is no less than one long hole in the middle of the mounting plate, the width of the long hole is greater than the diameter of the tensile bolt, the lower end of each tensile bolt passes through the long hole and extends to the bottom of the mounting plate, and the fastening nut can be stuck on the mounting plate at the long hole; No less than two locating nuts are fixed on the mounting plate on the outside of the long hole. The utility model has a reasonable and compact structure, can quickly and easily disassemble graphite and silicon carbide bearings of different diameters and lengths, and will not cause damage to the inner bearing when dismantling, thus greatly reducing the increase in product cost caused by damage to the inner bearing, and also greatly improving the work efficiency of dismantling the inner bearing.
Axle hub inner bearing puller, including pull-out, guide post and guide block, the guide block is threaded on the guide post, the guide post is fixed on the pull-out, and the guide block has bolts in the same direction as the guide post. The utility model can be used to easily pull out the bearing in the truck axle hub without damaging the axle shell and other valuable parts.
