Multitemp LRL 3
Other companies also sell similar types of grease. For more detailed information, ask the supplier to find
an equivalent for you by telling them the name of the grease.
Warning: Never use any fluorine-based grease. Mixing with lithium-based grease with other
grease not only reduces the performance of the grease, it may even cause damage
to the actuator.
[2] Cleanroom Type
On the cleanroom type, the urea based grease that has great low particle-emission, stable torque
characteristics, brilliant lubrication and anti-dust effect equivalent to the lithium based grease is
applied. IAI uses the following grease in our plant.

Warning:
࣭
Apply low particle-emission grease on Cleanroom Type Actuator. Particles may be
generated if standard grease is applied.
࣭
Do not attempt to apply fluorine and lithium grease. Mixing with urea based grease
may lose the lubrication performance the grease originally has, which may result
in such cases as damaging the mechanical parts or causing a drop in the
cleanliness characteristics.
