11. Weights and Measures
Lubricating oil
Refer to actuator name plate. IQ
actuators are lubricated using the
oil grades specified below. They are
factory filled for life and in normal
service do not require topping up.
Ambient temperatures ranging from
-30 to 70 °C (-22 to 160 °F): SAE 80EP
lubricating oil.
Ambient temperatures below -30 °C
(-22 °F): Mobil SHC 624 lubricating oil.
Food grade lubricating oil
If user specified, IQ actuators will
be filled with Hydralube GB Heavy
food grade lubricating oil suitable for
temperature range -30 to 70 °C
(-22 to 160 °F).
Grease – Side handwheels
Extreme pressure multipurpose grease
MULTIS MS2 or equivalent. For low
temperatures use a grease suitable for
use at -50 °C such as Optitemp TT IEP.
Grease – Linear drive unit
IQL and IQML linear drive assemblies
should be regularly lubricated using
extreme pressure multi-purpose grease
MULTIS MS2 or equivalent.
Grease – Base assembly
O-rings use either Multis EP2 /
Lithoshield EP2 or equivalent for all
temperature ranges between
-50 and +70 ºC (-58 and +158 ºF).

*Oil capacity shown for Top Hand
Wheel actuators. Side Hand Wheel
actuator capacity is 2.20 (4.65).
Inverted installation
If inverted installation (base uppermost)
was specified with the order, Rotork
will oil fill to the quantities shown
in the table below and the actuator
will be labelled “Factory filled with
additional oil for inverted use”. If not
specified with order but site installation
will be inverted, to ensure adequate
lubrication the installer must top up
the oil before installation using the top
oil plug by the amount indicated in the
table.
For oil plug location, refer to section
1.1.
