Reduces setup and downtime of your expensive processing machine by up to 80%!
Spreitzer’s concentricity gages offer high flexibility, fast set-up times, high runout accuracy and are suitable for different geometries.
The concentricity gages are used for inspection tasks on external, internal and flat surfaces of rotating parts. In particular, the coaxiality of two or more diameters can be determined and axial runout measurements can be performed. In the RPG, RPG AL RPG mini and RPG micro type, the workpiece is unwound between three rollers without a center. A concentricity of 0.002 mm is achieved. The robust construction with preloaded roller bearings of the support rollers is designed for durability. A diameter range of 0.8 to 240 mm can be covered with the specific product versions.

In the measurement technology, concentricity gages occupy a particularly important position. A suitable measuring setup as well as corresponding precision of the concentricity gage are the basis for a precise measurement.
Explanation of terms:
Coaxiality and concentricity deviation.Deviations that relate to a reference axis. The workpiece rotates around this axis when the toleranced element is measured. Runout deviations occur due to axis misalignment, lack of coaxiality or due to roundness deviations
