This is designed according to the bearing size. In addition, there are a 3-hook puller (See Fig. 31) and a 2- hook puller for wide-range use.PressFig. 31In addition to these, when it is difficult to remove the inner ring due to high shoulders, several holes for removal pins are made through the shoulder, or sev-eral hook grooves are cut in the shoulder as shown in Fig. 32 and Fig. 33.When a bearing is not to be used again after removal, it may be removed by heating with a torch lamp.Fig. 29Fig. 32Fig. 30Fig. 33A60ABCDEFGHIJKLM
