Question for GATE Past Year Questions: Limits, Fits & Tolerances
Try yourself:In an interchangeable assembly, shafts of size mm mate with holes of size mm. The maximum possible clearance in the assembly will be
[ME 2004]
Explanation
Minimum shaft size = 25.000 – 0.04 = 24.96 mm
Maximum hole size = (25.000 + 0.02) = 25.02 mm
Maximum possible clearance = Maximum size of hole – minimum size of shaft
= 25.02 – 24.96 = 0.060 mm = 60 micron

Question for GATE Past Year Questions: Limits, Fits & Tolerances
Try yourself:The dimensional limits on a shaft of 25h7are
[ME 2003]
Explanation
Shaft Basic system
i = 0.31 microns
IT7 = 16i = 16 × 1.31= 20.96 microns.
shaft Tolerance = 25 – (20.96 × 10–3)
= 24.979mm.
