The opening of the cylindrical hole bearing is the most simple to disassemble the inner ring. At this moment; pay attention to let the inner ring accept its pulling force. (Fig. 12)
Moreover; the puller shown in Figures 13 and 14 is often used; whatever it is; its claws must be firmly stuck on the end face of the inner ring. To do this; Machining grooves at the shoulder; for use with a puller (Figure 14)
The inner ring of the large bearing is disassembled and selected by the hydraulic method. The oil hole is arranged on the shaft; the high-pressure oil is introduced into the cooperation surface; the bearing with large width is easy to be pulled; and the puller can be used together for the opening operation.
The inner ring of NU type and NJ type cylindrical roller bearings can be opened by induction heating. This method is to heat the part in a short time; the inner ring is expanded and then pulled out. (Fig. 15) When the inner ring of the bearing is used; the induction heating method is also used.
