Accurate and reliable measurements are a key factor in today’s competitive manufacturing environment. Universal Punch’s patented Concentricity Gaging Systems offer less than 2 microns accuracy that has proven results in a variety of industrial applications. Continuous improvements to its modular design adapts to customer requirements and provides the flexibility necessary for maintaining quality.

There are two classifications calibrated and directly traceable to (N.I.S.T.). Standard Black Gages are guaranteed to be better than ≤ 4µm (.00016″) accuracy. Precision Gold Gages are guaranteed better than ≤ 2µm (.00008”) accuracy.


  • Adjustable multi-position top arm yoke assembly offers a variety of clamping pressures and positions to accommodate a range of part diameter sizes.
  • All standard indicator carriers have fine adjustment screws that provide accurate indicator probe positioning, zeroing and provide smooth indicator movement to increase measuring performance and accuracy.
  • All gages come standard with a manual drive timing belt pulleys system that provides a constant smooth part rotation when inspecting. (Optional) 110/220 volts AC/DC fixed speed or variable speed motorized drive systems are available.
  • All carriers offer a variety of positions that move along the Z-axis of the carrier rod assembly. The carrier tilts 90 degrees to facilitate easy loading and unloading of parts.
