Product data

Metric series Inch series

Dimension ISO 2982-1, except for the bore diameter of sleeves ANSI/ABMA Std 8 2
standards for inch shafts

Tolerances Bore diameter: JS9
Width: h15

External taper 1:12 as standard
1:30 as standard in the 40 and 41 dimension series

Thread Bore diameter < 200 mm (size ≤ 40): Bore diameter ≤ 12 in. (size ≤ 64):
metric thread in accordance with ISO 965-3, matching Uniied Special Form ANSI/ASME B1 1
the included SKF lock nut
Bore diameter ≥ 12 7 /16 in. (size ≥ 68):
Bore diameter ≥ 200 mm (size ≥ 44): ACME thread class 3G
metric trapezoidal thread in accordance with ISO 2903,
matching the included SKF lock nut

Shaft tolerances h9�
Total radial run-out: IT5/2 – ISO 1101
Adapter sleeves adjust 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 geometrical tolerances must be kept within narrow limits
as they directly affect the shaft positioning and vibration
