Lubricant Recommendation and Requirements

Lubrication Utilization
Operating Condition(s)
Definition
Reduction Factor (Multiplier)
Duty Time (DT)
(Total engine running time)
-
Extremely high DT
Over 1,250 hours/year
0.5
High DT
Over 500 hours/year
0.7
Extremely low DT
Less than 0.5 hours/year
0.8

(Permanent or long-term)

Extremely changeable
Between -10

Between 80 to 90%
0.9
Application example:
Extremely low DT + extremely low ambient tempe high speed + 87% utilization
> 0.8 * 0.9 * 0.8 * 0.9 = 0.51 reduction factor
(Lubrication maintenance interval) 10 years * 0.51 = 5.1 years (62 months).
!
CAUTION
This calculated maintenance interval applies neither to the maintenance of output type A
(threaded bushing) units nor to the maintenance of linear and spindle drive units. These units
must be periodically lubricated (at least every 6 months) via the grease nipples (see Section 3).
During maintenance of our actuators, remove and replace old grease with new one.
Mixing of different lubricant types is NOT permitted.
Quantities needed for lubricant service are listed in Section 3.
