A.無帽緣式固定襯套
                                                  A.HEADLESS PRESS FIT BUSH




          ●  無帽緣固定式襯套,其外徑是p6孔請用H7公差,以利壓入配合。
          ●  如需要高精度的場合,襯套外徑由實測而得,而襯套承板孔徑比
             襯套外徑小0.004~0.006mm。
          ●  In case of normal precision(general):
             Bore a hole in bush plate at  H7in which the bush is straight fitted.
          ● In case of requiring high precision:
              Bore in bush plate with diameter less some0.004~0.006 of bush   thanO.D.
              actually measured.
