10.5 Basic Lubricant Service Interval

On actuator maintenance, the old grease must be removed completely and replaced by a new one.
NOTE: The service interval for Schiebel actuators is 10 years from the date of delivery by Fa. SCHIEBEL
Antriebstechnik Gesellschaft m.b.H, A-1230 Vienna. The functionality and operating life of the lubricants is,
however, dependent upon operational conditions. It may be necessary to take reduction factors into account.

Lubricant maintenance interval
CAUTION: A thusly calculated maintenance interval does not
apply to the maintenance of the output 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 10.3, page 26)!
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.

10.6 Lubricant Requirements

Type of actuator Main gear
AB3/5 1kg (1l oil)
AB8 1kg (1l oil)
AB18 1kg (1l oil)
AB40/80 1,5kg (1,5l oil)
AB100/200 3,5kg (3,5l oil)
When lubricating precision components, such quantities of lubricant are to be used as to ensure fine moistening
Definition
(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
over +50°C
below -25°C
(at main shaft of actuator)
over 80 rev./min
(with respect to nominal performance)
over 90%
between 80 and 90%
