About d11
d11 denotes a shaft tolerance zone with running clearance deviation in the ISO 286 system. It is used in H11/d11 (Free-running parts with generous clearance, e.g. loose bushes and idler wheels on rough shafts.).
At Ø25 mm d11 is −0.065 / −0.195 mm, i.e. 24.805 to 24.935 mm.
How the limits are calculated
d11 uses grade IT11 (a standard tolerance of 130 µm at 18–30 mm). Fundamental deviation: es is tabulated directly by ISO 286-1 Table 2; ei = es − IT11. See the fundamental deviation table for every letter. Values per ISO 286-1:2010.
