J.A. King Company Newsletter – January 2018

Ask the Experts: What is the difference between roundness, cylindricy, coaxiality, concentricity, runout, and total runout?

J.A. King Company Newsletter - January 2018 1If your New Year’s resolution was to better understand Geometric Dimensioning & Tolerancing (GD&T) terminology, J.A. King is here to help! We have found that there is a fair amount of confusion regarding the differences between roundness, cylindricity, coaxiality, concentricity, runout and total runout. To help you better understand the differences and how they relate to one another, we have broken down the terminology in this month’s Ask the Experts article.


While we hope these descriptions of radial GD&T parameters are helpful to you, the actual measurement of these parameters can be quite complex. They require the proper selection of reference elements and filtering techniques, which help in interpreting the collected data. We encourage you to talk to our specialists for further information on these topics.

In fact, for almost any type of measurement you need, J.A. King is here to help! We sell and calibrate the equipment that you require for accurate repeatable measurements. If your team is too busy to measure your parts, or you need an impartial third party evaluation, we have the expertise and equipment to meet your needs. Contact us today to learn more!
