Product data

Dimension standardsISO 2982-1:1995
TolerancesBore diameter: JS9
Width: h13
External taper
1:12 as standard
1:30 as standard in the A(O)H 240 and A(O)H 241 series
ThreadBore diameter ≤ 180 mm (size ≤ 38): metric thread in accordance with ISO 965-3:1998, matching the appropriate SKF nut for removal
Bore diameter ≥ 190 mm (size ≥ 40): metric trapezoidal thread in accordance with ISO 2903:1993, matching the appropriate SKF nut for removal
Thread requirements for other lock nuts than listed in the product table:
Bore diameter ≤ 180 mm (size ≤ 38):
Tolerance 5H – ISO 965-3:1998
Bore diameter ≥ 190 mm (size ≥ 40):
Tolerance 7H – ISO 2903:1993
Shaft tolerances
h9
Cylindricity: IT5/2 – ISO 1101:2012
Withdrawal sleeves adapt to the shaft diameter, so that wider diameter tolerances can be permitted compared to the seat of a bearing with a cylindrical bore. However, the form tolerances must be kept within narrow limits as the accuracy of form directly affects the running accuracy of the bearing.
