Gage Types

A Solution For Every Challenge

With increased demand for efficiency and performance in the next generation of engines, precise measurements are of critical importance. Adcole gages are up to the challenge.


Companies at the forefront of the aerospace industry require metrology solutions to match their precise performance needs.


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


Adcole products bring sub-micron accuracy and conformance in camshaft and crankshaft measurement to factory floors across the automotive industry.

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.


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.


With a large selection of gages that can accurately and efficiently measure crankshafts, Adcole’s optical metrology products are applicable in a wide array of industries.

Custom 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.


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.


Tolerances and standards for gears grow tighter every year. Adcole’s gages are specifically designed to accommodate these high standards.

Adcole’s team of experts understands that, when it comes to locomotive engines and rails, precise, repeatable measurements are of the utmost importance, which is why our engineers have designed our gages to provide reports you can rely on.


Our sophisticated metrological machines provide dependable analysis of parts for use in marine systems.

Max Height of Profile

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.

Max Peak Height of Profile

The maximum peak height of profile is the height of the highest peak from the mean line of the component profile, as defined on the sampling length.

Metrology Software + 3D Mapping

Adcole provides comprehensive metrology software for enhanced measurement analysis. Powerful productivity suites allow for in-depth measurement analysis and straightforward gage operation, from 3D mapping software to simplified gage programming with Adcole’s Program Builder.


Measured parallelism, sometimes called journal parallelism, is based on the radial measurements of the two outside cuts of the journal.


Perpendicularity is based on the strain gage and carriage readings taken over a full revolution. The perpendicularity calculation is based on the difference between the face axis and reference axis


Adcole’s rugged gages, such as the Model 911, are designed to measure pistons and other cylindrical components in the most demanding production environments.

Pumps & Compressors

Using Adcole’s metrology systems to assess industrial pump parts and compressors improves production output, helps to identify and solve manufacturing problems, and saves engineers troubleshooting time.

RMS Roughness

Roughness average is an average taken from measuring the surface texture of a component. It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth.

Straightness is defined as the difference between the maximum positive deviation (Rmax) and the maximum negative deviation (Rmin) , relative to the Least Squares line of a single vertical measurement.

Surface Finish

Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).

Surface Finish/Roughness Measuring Gages

Adcole introduced the very first semi-automatic surface roughness gages for production. The robust construction and anti-vibration technology provide highly accurate surface roughness measurements, even in harsh production environments.


Taper is a determination of angle and form errors on the outside and inside tapers, and parts with angular surfaces.


The crank throw is a measure of the distance from the center-line of the main journal to the center-line of the rod journal. This distance could be considered the radius of the crank arm. Twice this measurement provides the stroke of an engine.
