coupling

Here the backlash between the cams of the coupling and the flexible spider/DZ element must be inspected by
means of a feeler gauge.
When reaching the wear limit

maximum friction

, the spider/DZ element must be replaced immediately,

irrespective of the inspection intervals.

In case of backlash > X mm, the flexible spider/DZ elements must be replaced.

Reaching the limits for replacing depends on the operating conditions and the existing operating parameters.

!

In order to ensure a long service life of the coupling and avoid dangers with the use in
hazardous locations, the shaft ends must be accurately aligned.
Please absolutely observe the displacement figures indicated (see table 9 to 11). If the
figures are exceeded, the coupling will be damaged.
