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.
