Air Probe Dimensional Data - Dual Master - Series 10 - 50
Body clearances
Clearances for series 10 thru 50 air gage
members are referenced to the maximum
material condition of the feature to be
inspected. Determine the body size of an air
probe by subtracting the clearance value
shown in the adjacent table from the minimum
part size. For air ring gages, add the value
shown to the maximum part size.
Clearance recommendations
Low clearance . . Class 1 -- for the highest
accuracy applications such as select fitting of
valve spools and sleeves where finishing
tolerance is less than .00016'' (4.1 μm).
Standard clearance . . Class 2 -- best for
most applications. Members are furnished to
this specification when no other specification is
given.
Extra clearance . . Class 3 -- for applications requiring extra gaging range such as grinding and honing operations where sizing information is required before the final size is obtained.
