is a low-maintenance coupling. We recommend to perform a visual inspection on the coupling
at least
once a year
. Please pay special attention to the condition of the coupling spiders.
•
Since the flexible machine bearings of the driving and driven side settle during the course of load, inspect the
alignment of the coupling and re-align the coupling, if necessary.
•
The coupling components have to be inspected for damages.
•
The screw connections have to be inspected visually.
!
Having started up the coupling the tightening torques of the screws have to be inspected
during the usual inspection intervals.
With the use in potentially explosive atmospheres observe chapter 10.2 "Inspection
intervals for couplings in
potentially explosive atmospheres".
We recommend to store major spare parts on site to ensure the readiness for use of the machine in case if a
coupling fails.
Contact addresses of the KTR partners for spare parts and orders can be obtained from the KTR homepage at
www.ktr.com.
KTR does not assume any liability or warranty for the use of spare parts and accessories
which are not provided by KTR and for the damages which may incur as a result.
