Design considerations

Abutment dimensions

To maximize the effectiveness of the insulation, SKF recommends the following guidelines for dimensioning the shaft and housing shoulders:
  • Bearings with a coated outer ring (fig. 1, designation suffix VL0241 or VL0246):
    housing abutment diameter ≥ Da min
  • Bearings with a coated inner ring (fig. 2, designation suffix VL2071 or VL2076):
    shaft abutment diameter ≤ da max
The values for Da min and da max can be obtained from the product tables:
