Bore Gage

August 29, 2008


PG-Series bore gages combine lab-precise accuracy (±0.000025 inch) with an all-mechanical design. The gages bring ID gaging to the manufacturing floor with no need for electrical or air connections, making them immune to fluctuations in line voltage or air pressure. The gages can be mounted at machining stations and unique gaging fixtures enable quick setup. The speedometer-type scale provides readouts down to 0.00005 inch for inspection of machining operations or fast sampling of large vendor lots. The gages can be used to examine the entire bore for diameter, taper, barrel, bell mouth, out-of-round and lobing. A sliding faceplate with adjustable stops permits end-to-end examination of bores. Stops can be set to allow examination of a particular section of the bore, with accuracy up to the edge of ports, lands and ends.
