Testing

Reduces setup and downtime of your expensive processing machine by up to 80%!

Runout inspection, runout testing right next to the machine. We offer centerless runout testers, bench centres with support prisms, concentricity gages with roll-off blocks and concentricity gauges with tailstocks. The runout test can be performed within 10 seconds without any prior knowledge.
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. The concentricity of a round profile is of considerable importance for the manufacture of shafts, bushings, gear wheels or bearings. Examples from the automotive industry: camshafts, crankshafts, cardan shafts, drive shafts.
With our concentricity gauges, 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.
