4.3.8 Coupling hubs
General
Note!
Standard hubs, clamping hubs and clamping ring hubs are
maintenance−free.
We recommend carrying out a visual inspection of the star−shaped
spider/ring gear and the system parts within the inspection intervals.
Note!
Tighten all screws to the coupling hubs and the motor fastening of
gearboxes in ATEX design with an intermediate strength screw retention.
