at 117,000 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone the annular envelope between 440 mm bore and 560 mm OD is about 94,248 mm² in cross section, which sets the 117,000 g mass at steel density for the 361 mm-long slit bush the OD-to-bore ratio is 1.27: the 560 mm sleeve OD is only 60 mm of section beyond the 440 mm seat, leaving room for the bearing outer ring without enlarging the housing bore with a 410 mm shaft this is one of the largest metric sleeves listed;
