Inspection intervals

no gases and vapours of
explosion group IIC
An inspection of the circumferential backlash and a visual inspection of the
components must be performed after 2,000 operating hours for the first time, at
the latest after 6 months after start-up of the coupling.
If you note insignificant or no wear on the components upon this initial
inspection, further inspections can each be performed after 4,000 operating
hours or at the latest after 18 months, provided that the operating parameters
remain the same.
If you note significant wear during the initial inspection so that it would be
recommendable to replace the components, please find out the cause
according to the table „Breakdowns“, if possible.
The maintenance intervals must be adjusted to the modified operating
parameters without fail.

An inspection of the circumferential backlash and a visual inspection of the
components must be performed after 1,000 operating hours for the first time, at
the latest after 3 months after start-up of the coupling.
If you note insignificant or no wear on the components upon this initial
inspection, further inspections can each be performed after 2,000 operating
hours or at the latest after 12 months, provided that the operating parameters
remain the same.
If you note significant wear during the initial inspection so that it would be
recommendable to replace the components, please find out the cause
according to the table „Breakdowns“, if possible.
The maintenance intervals must be adjusted to the modified operating

coupling
Here the backlash between the spline
of the hub and the sleeve must be
inspected via torsional backlash, each
separately from the driving and the
driven side.
When reaching the torsional backlash

, the respective coupling half
(hub and sleeve) must be replaced
immediately, irrespective of the
inspection intervals.
