Fig. 2.99. Marking of dimensional group of inserts of radical bearings

When replacing inserts of the standard size it is necessary to use inserts of one dimensional group specified on a bearing cover. There are dimensional groups of inserts designated by "1", "2", "3" (fig. 2.99).

Internal diameter of the lower head of a rod:

marking "1"..... 51,000–51,007 mm;

marking "2"..... 51,008–51,013 mm;

marking "3"    ..... 51,014–51,020 mm.

The standard sizes of inserts on their thickness:

marking "1"    ..... 1,485–1,488 mm;

marking "2"    ..... 1,488–1,491 mm;

marking "3"    ..... 1,491–1,494 mm.

Remove the remains of a calibration wire from the working surfaces of a neck and an insert.
