•
Lightly unscrew the clamping screws and fit the clamping set KTR 620 on the hub/hollow shaft outside (see
illustration 5 and 6).
The external surface of the hub (hollow shaft outside) can be lubricated in the area of the fit
of external clamping set.
!
Mount the shaft before tightening the clamping screws.
•
Lightly hand-tighten the clamping screws and align the clamping set.
•
Afterwards tighten the clamping screws gradually in several revolutions evenly one after another (see illustra-
tion 7) into the front screw-head sided surface of external and internal ring. Consequently correct clamping of
external and internal ring can be inspected visually (see illustration 8).
•
When tightening the clamping screws the maximum screw tightening torque (see table 1) must not be exceed-
ed.
Protuding of the internal ring up to 0.5 mm is permissible with a QPQ coating.
