Supplied unit mounted as standard
As a special case, air ring can be supplied on MOD-2A up to dia. 50 mm only, to suit super blind and less land
Air ring gauge for 0.0005 mm least count are given up to Ø 50 mm only
Each air ring gauge requires two setting masters to set the air ring on the read-out unit. The difference between the high and low setting masters supplied covers the component tolerance or the maximum range mentioned in the above table, whichever is lower
The minimum gauging land “E” and “F” mentioned above, is excluding chamfer distance and fillet radius
For special blind shafts (super blind- ‘E’ less than mentioned in the above chart) or any other special requirement (3 Jet design to check lobing), please send the component drawing and ask for a quote

MOD 1A = PFL Air Gauge Unit Module 1A
MOD 2A = PFL Air Gauge Unit Module 2A
CL = ClearLine air gauge unit
Important rule in air gauging
Lesser the clearance, higher the accuracy and vice versa.
