Mounting screw
x It is recommended to use high-tensile bolts with ISO-10.9 or more.
x Make sure to have the effective length of screw engagement described below or more for the
tightening of a bolt and a female screw.
When female screw is on steel ĺ thread length same as nominal diameter
When female screw is on aluminum ĺ 1.8 times of nominal diameter
Caution: x Pay attention when selecting screws. If a bolt other than those of the instruction is
used, damage on tapped holes or unexpected accident or failure due to insufficient
strength on the actuator attachment or interference on the driving area.
x There may be a case that water or oil of the grease drops from the seals on the
openings at the bottom surface.
If the unit is installed as shown below, use it in a way that should be no problem even
if water or oil drops below the actuator. Do not place anything that may cause a
problem if water or oil is dropped on it. Otherwise apply a cover on it.
Water or oil may drop
in this space.
