It is equipped with a pair of Morse centers of 4# rigidness, which escalates the measuring precision and increases the support strength on measured parts. It can be used for the radial run-out, end run-out and tilting circular run-out. The design of the meter stand is deliberate and reasonable, and it can be adjusted easily to all directions. The operation is easy and the rigidness of the meter stand is good, which improved the delicacy of the instrument. It is especially suitable for the measurement of grinded parts.

Main parameters:
(1) Radial rotating precision: 0.001mm;
(2) Parallelism the side guideway on the span and the link line of the two centersL 0.005mm (type I), 0.007mm (type II), 0.002mm/100;
(3) Maximum diameter of the tested part: 250mm;
(4) Maximum length of the tested part: 500mm, 800mm
