Air calipers are supplied hand held as standard
# not supplied for use on ± 0.025 mm ClearLine unit
General Notes
Air calipers for 0.0005 mm least count are given up to Ø 50 mm only
Each air caliper requires two setting masters to set the air caliper 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 (multi jet design air caliper), please send the component drawing and ask for a quote
