Environment - SMC Networks JMDB 32 Series Operation Manual

Do not apply excessive lateral load to the piston rod.

Calculation for excessive lateral load:
Minimum operating pressure value after the device is mounted (MPa) = Cylinder's
minimum operating pressure(MPa) + {Load weight(kg)
× Guide friction coefficient / Cylinder's cross section (mm
If the product is found to operate smoothly with the calculated pressure, it has been
determined that the alignment of the guides have not created additional loading on
the cylinder.
Do not let foreign matter such as cutting chips get into the product from the

supply port.
When the product is installed on a machine on site, the debris from drilled mounting holes can
get in the supply port of the product. Take sufficient care to prevent this.

2-4. Environment

Warning
！
Do not use in an atmosphere having corrosive gases, chemicals, sea water,

water, water steam, or where there is direct contact with any of these.
Do not expose the product to direct sunlight for an extended period of time.

Do not use in a place subject to heavy vibration and/or shock.

Do not mount the product in locations where it is exposed to radiant heat.

Do not use in dusty locations or where water or oil, etc., splash on the

equipment.
When using auto switches, do not operate in an environment with strong

magnetic fields.
A decrease in grease base oil may be accelerated by the properties of

compressed air used in pneumatic equipment, the external environment,
or operating conditions, etc., and the resulting drop in lubricating
performance may have an effect on equipment service life.
Avoid storing the product in humid conditions.

Store the product with the piston rod retracted and avoid humidity, in order to prevent
generation of rust.
Caution
！
chined part
Ma of the piston rod and tie rod are not plated.

Be careful there is possibility to occur rust during usage or long term storage.
Preparation before piping

Before piping, perform air blow (flushing) or cleaning to remove any cutting chips, cutting oil,
dust, etc. from the piping and fitting.
Wrapping of pipe tape

When screwing piping or fittings into ports, ensure that chips from the pipe threads or sealing
material do not enter the piping.
Also, if pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end of the threads.
Wrap this way.
Leave 2 threads exposed.
