Precise runout inspection. Within 10 seconds.

The concentricity gages are used for inspection tasks on external, internal and flat faces on rotating parts. Particularly, the concentricity of two or more diameters can be determined and axial run-out measurements performed.

Features:

  • Robust design with pre-loaded roller bearings
  • Concentricity < 0,002mm
  • Simple handling, quick measurement
  • Suitable for transmitted light

RPG micro for diameters 0,8-10mm

 The concentricity gage type RPG micro is especially suitable for the use on measuring microscopes from different manufacturers. The fixturing holes in the base of the gage allows universal mounting options.

RPG for inside and outside diameters 0,8 – 50mm

The concentricity gages type RPG are especially designed for mea-suring in the batch production. Two swivelling gauge holders are used for the external gauging, one gauge slide is used for the internal gauging of rotating parts. All gauge holders can be continuously variable moved on the guide columns. The swivelling in and out of the measuring holder against positive stops prevents repeated adjustments of the measuring instrument at the workpiece.

Features:spreitzer Concentricity-gage-RPG-450
• robust design with pre-loaded roller bearings
• simple handling, quick measurement
• for inspections in batch production by swivelling gauge holder and measuring slide
