[mm], the nylon sleeves 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
potentially explosive atmospheres, the shaft ends must be accurately aligned.
Please absolutely observe the displacement figures specified (see tables 6 and 7). If the
figures are exceeded, the coupling will be damaged.
