  • 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
