Lubricant maintenance interval
WARNING: A thusly calculated maintenance interval does not apply to the maintenance of the out-
put type A (threaded bushing), nor to the maintenance of the linear and spindle actuator units. These
must be regularly re-greased (at least once every six months) at the lubricating nipples (see section
7.3, page 14)!
During actuator maintenance, the old lubricants must be thoroughly removed and replaced by fresh ones.
No mixing of different makes of lubricant is permitted!
The quantities needed for lubricant service can be seen from the table below.

7.6 Lubricant Requirements

Type of actuator
AB3/5
AB8
AB18
AB40/80
AB100/200
When lubricating precision components, such quantities of lubricant are to be used as to ensure fine moistening
of the sliding surfaces.
(Total of motor running time)
over 1,250 hours/year
over 500 hours/year
less than 0.5 hours/year
(Permanent or long-term)
between -10 and +50 C
(at main shaft of actuator)
(with respect to nominal performance)
between 80 and 90%
10 years x 0.51 = 5.1 years (62 months).
