The deep groove ball bearings and the Y-bearings are produced to Normal tolerances in accordance with
  • ISO 492:2002 (Normal) and
  • ISO 9628:1992 (table), respectively.
However, because the bearings have been especially surface treated to protect against corrosion and improve running properties, there may be slight deviations from the standard tolerances. Any such deviations will have no influence on mounting or bearing operation.
The Y-bearings for inch shafts are made to the same tolerances as the corresponding basic bearing for metric shafts.
The tolerances for the height of the shaft axis above the support surface, dimension H1 of the plummer block units are 0/–0,25 mm.
