There are a wide variety of roller bearings available which serve a diverse range of applications. Tapered, cylindrical and needle roller bearings are just a few of the types available. Roller bearing elements require good surface finish and form and precise dimensions to provide low noise and high load capacity in the roller bearing assembly.

In this Application Note we consider the challenges faced in measuring roller bearings. We show how using Taylor Hobson's Form Talysurf® PGI NOVUS and Metrology 4.0 software provides a unique, rapid and precise solution for measurement of all four sides of the roller bearing, removing reliance on external fixture datums. This new method greatly improves the throughput of parts, helping to keep up with the demands of high volume production. The NOVUS dual bias gauge gives accurate analysis of crucial parameters and dimensions all of which are key to the performance of the bearing. Automatic alignment eliminates operator error, providing confidence in the measurement setup and accuracy of results.
