In case of a backlash > X mm, the flexible spider must be replaced.
Monitoring of the general condition of the coupling can be done both at standstill and during operation. If the
coupling is tested during operation, the operator must ensure an appropriate and proven test procedure (e. g.
stroboscopic lamp, high-speed camera, etc.) which is definitely comparable to testing at standstill. If any
distinctive features occur, an inspection must be made with the machine stopped.
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 indicated (see table 12 to 14). If the
figures are exceeded, the coupling will be damaged.
