Angularity describes the specific orientation of one feature to another at a referenced angle.

Automated Gage Systems


Automotive manufacturers face high throughput demands while delivering peerless quality, often requiring 100% inspection — that’s why they rely on Adcole in-line and audit lab gages to ensure that sub-micron accuracies are met. From fundamental dimensional measurements to chatter and lobing — Adcole provides solutions including automatic data collection and part traceability.

Avg Max Height of Profile

The average maximum height of profile is a computation derived by taking an average as defined by the sampling of the maximum height of a component’s profile: this parameter is frequently used to check whether the profile has protruding peaks that might affect static or sliding contact function of a component.

Axial Location

Axial location is the measurement of where the central axis of a component is located when the component is rotated, in order to know if the rotating component is within parallel specifications. An angular error in the component will contribute to greater axial runout.


The automotive industry has counted on Adcole’s Trusted Accuracy to measure axles for decades, resulting in increased productivity, recognized quality and rapid return on investment.

Cam Lobe Lift Error

Adcole gages and software provide accurate data about camshaft lobe asymmetry with unmatched levels of repeatability.


Gage-to-gage repeatability ensures that camshafts and other parts are manufactured to identical standards/tolerances across the entire plant—or even company-wide.

Center Deviation

Center deviation is based on the three radial cuts of the lobe. It is the difference between the measured diameter of the center cut and the average of the diameters of the two outer cuts.


When profile error of your cylindrical part has a repeating, undulating pattern, it is said to exhibit Chatter. Adcole gages provide chatter measurement to find the specific Undulations per Revolution and amplitude results for a recurring signal


Concentricity is a complex tolerance used to establish a tolerance zone for the median points of a cylindrical or spherical part feature. Concentricity is generally reserved for high-precision parts, and only when there is a need to control median points.

Crankshaft & Camshaft Measuring Gages

Adcole crankshaft and camshaft gages are designed to meet the demands of production lines while providing the very best in accuracy, versatility and reliability. Their ruggedness and superior repeatability set the standard in the world of metrology.

Custom Shaft Gages

Adcole automatic and semi-automatic cylindrical coordinate measuring machines are known for their exceptional accuracy and high repeatability. We can design or customize a coordinate measuring machine for virtually any application to accommodate your production and quality control requirements.


Cylindricity is defined as the difference between the maximum radius and the minimum radius of all three-journal measurements relative to the axis of the outer cuts.


The measured diameter is based on a single radial measurement. The average of the radial readings of the follower is used to compute a best fit circle. The follower readings are summed up and divided by the number of data points per revolution, and then multiplied by two to get the average diameter.

Eccentric Shafts

As pivotal parts of steam locomotives and other engines, eccentrics must be measured to the kind of high standards for which Adcole gages are specifically designed.

Electric Vehicle (EV)

Feature/Locator Presence

Adcole gages provide extremely accurate feature/locator presence
measurements, enabling manufacturers to maintain strict quality control standards.


Flatness is measured using a height gauge run across the surface of the part where the reference feature is held parallel, being certain that any point along the surface does not go above or below the tolerance zone. Adcole gages deliver sub-micron measurement accuracies, providing 3D measurement about the length and width of the part — ensuring the entire surface is in tolerance.

The maximum height of profile is defined on the sampling length: like the average maximum height of profile, this measurement is typically used to check whether the profile has protruding peaks that might affect static or sliding contact function of a component.

Max Peak Depth of Profile

The maximum peak depth of a profile is the depth of the deepest valley from the mean line of the component profile, as defined on the sampling length.
