The material of the cylinder rod is heat-treated stainless steel
(HRC60). The roughness of the spherical contact of the
attaching part (Equipment, Work, etc) should be Rz6.3 and the
material should be HB100 or greater (Aluminum material: 2000
line or 7000 line or equivalent) When higher precision or longer
service life is required, we recommend using a heat-treated
ma flat polished machined material (Rz0.8)
Also, although applying grease on the spherical contact parts
will make the operation more smooth and reduce the abrasion,
use caution to prevent any grease from being applied to the
cylinder’s sliding surface.

1. The component parts of the metal seal cylinder are
manufactured to precision tolerances, and therefore
cannot be disassembled.

Caution
1. Lubrication of non-lube type cylinder
Do not apply lubrication when controlling for low speed or
controlled output. If lubrication is applied, there may be
changes in operating resistance due to factors such as the
viscosity and surface tension of the oil. Also, use a metal seal
type when using solenoid valves for cylinder actuation. If a
rubber seal type is used, there may be an increase in
operating resistance due to grease sprayed from the main
valve.
Lubrication is also unnecessary for high speed actuation, but
in the event that lubrication is applied, use turbine oil class 1
(with no additives) ISO VG32. (Do not use spindle oil or
machine oil.)

Specific Product Precautions
Be sure to read this before handling.
Refer to back page 1 through to 3 for Safety Instructions and Actuators Precautions.
1. When mounting, thoroughly flush out the connector
piping and be sure that dirt and chips, etc., do not
get inside the cylinder.
2. Install an air filter with a nominal filtration degree
of 5 m or less on the air supply. Furthermore, when
controlling for low speed or controlled output, use
clean air (atmospheric pressure dew point tempera-
ture of –10C or less). Installation of a mist separator
(nominal filtration degree 0.3 m or less) is also
recommended.
3. Use a metal seal type when using solenoid valves for
cylinder actuation. If a rubber seal type is used, there
may be an increase in operating resistance due to
grease sprayed from the main valve.
4. This cylinder cannot be used at the end of its stroke.
Use it with an intermediate stroke of 10 mm.
5. The rod end should not come in direct contact with an
equipment or workpiece. Also, make sure that the
opposite side of the rod end is flat to make
point-contact with the spherical surface of the rod end.
6. When connecting, be sure to align the rod axis with
the load and the direction of movement.
The allowable angle of the cylinder’s mounting
surface in an equipment should be 3 or less.
(1 or less is recommended.) When not properly
aligned, a lateral load will likely be applied to the rod
and the spherical surface will likely skid. This will
result in a reduction or dispersion of thrust and
likely a malfunction.
