Air Probe Dimensional Data-Single Master – series 60 – 80

Clearance recommendations Series 60 thru 80
Clearance values for single mastered gaging members are referenced to the nominal master sizes. Users should pick clearances that allow the probe to enter the workpieces at their maximum material condition, and at the same time, not have excessive clearance at the minimum material condition. To determine the body size of a single master air probe, subtract the clearance value shown from the nominal master ring. For air ring gages, add the value shown to the nominal setting master.

Guide lines for clearances are as follows:
Product tolerance WGC specs.
.00001″-.00012″ (.2µ – 3µm) 62, 71
.00012″- .0004″ (3µ – 10µm) 63, 72
.0004″ – .0020″ (10µ – 50µm) 64, 73
.0020″ – .0040″ (50µ -100µm) 65

Best accuracy will always be obtained with single mastered gages by mastering near the middle of the product tolerance.
