Ground (P0-P5)

These geometric tolerances apply whenever there are no further information. The charts below apply for all ground ball screws.

For Measuring of run-out tolerances on shaft, we recommend to hold the shaft between centers and turn it consistently during the measurement. To measure the concentricity of the nut, it is necessary to turn the nut on the shaft while the shaft stands still.
