including our products must be performed by an operator who is
appropriately trained and experienced.
 Do
not service or attempt to remove product
machinery/equipment until safety is confirmed.
1) The inspection and maintenance of machinery/equipment should
only be performed after measures to prevent falling or runaway of the
driven objects have been confirmed.
2) When the product is to be removed, confirm that the safety
measures as mentioned above are implemented and the power from
any appropriate source is cut, and read and understand the specific
product precautions of all relevant products carefully.
3) Before machinery/equipment is restarted, take measures to
prevent unexpected operation and malfunction.
 Contact SMC beforehand and take special consideration of
safety measures if the product is to be used in any of the
following conditions.
1) Conditions and environments outside of the given specifications, or
use outdoors or in a place exposed to direct sunlight.
2) Installation on equipment in conjunction with atomic energy,
railways, air navigation, space, shipping, vehicles, military, medical
treatment, combustions and recreation, or equipment in contact with
food and beverages, emergency stop circuits, clutch and brake
circuits in press applications, safety equipment or other applications
unsuitable for the standard specification described in the product
catalogue.
3) An application which could have negative effects on people,
property, or animals requiring special safety analysis.
4) Use in an interlock circuit, which requires the provision of double
interlock for possible failure by using a mechanical protective
function, and periodical checks to confirm proper operation.
 Always ensure compliance with relevant safety laws and
standards.
All electrical work must be carried out in a safe manner by a qualified
person in compliance with applicable national regulations.
Caution
 The product is provided for use in manufacturing industries.
The product herein described is basically provided for peaceful use in
manufacturing industries.
If considering using the product in other industries, consult SMC
beforehand and exchange specifications or a contract if necessary.
If anything is unclear, contact your nearest sales branch.

3 Installation
3.1 Installation
Warning
Do not install the product unless the safety instructions have been read
and understood.

Do not apply strong impacts or excessive moments to the slide
table (slider).
The slide table (slider) is supported by precision bearings. Therefore, do
not apply strong impacts or excessive moment, etc., when mounting
work pieces.
 Align carefully when connecting to a load having an external guide
mechanism.
Mechanically jointed rodless cylinders can be used with a direct load
within the allowable range for each type of guide, but careful alignment
is necessary when connecting to a load having an external guide
mechanism. As the stroke becomes longer, variations in the centre axis
become larger. Consider using a flexible connection method (floating
mechanism) that is able to absorb these variations. Furthermore, use
the special floating brackets which have been designed for series
MY1B.
 Do not scratch or gouge the cylinder tube by striking or grasping it
with other objects.
Cylinder bores are manufactured to precise tolerances therefore even a
slight deformation may cause malfunction.
 Do not use until you can verify that equipment can operate
properly.
Verify correct mounting by suitable function and leakage inspections
after compressed air and power are connected following mounting,
maintenance or conversions.
 Instruction Manual.
The product should be mounted and operated after thoroughly reading
the manual and understanding its contents. Keep the instruction manual
where it can be referred to as needed.
 Ensure that the air supply system is filtered to 5 microns.
 Provide intermediate supports for long stroke cylinders.
Provide intermediate supports for cylinders with long strokes to prevent
bending of the tube, and deflection due to vibration and external loads.
100 ~ 1000 mm/s
1.7 J
 Intermediate stops.
3.4 J
Due to the compressibility of air, it is difficult for this product to make a
6.2 J
piston stop at the required intermediate position accurately and
Gas
precisely.
1 and 2
Mechanical joint rodless cylinder has a special seal in the construction,
and this causes a small amount of external air leakage. A three position
closed centre type directional control valve may not hold the slide table
in the intermediate position for an extended period of time, and the
speed may not be controlled when restarting the operation.

 Do not install in a location subject to vibration or impact. Check the
product specifications.
 Do not mount in a location exposed to radiant heat.
 Do not use in case of heavy dusty environments where dust can
penetrate into the cylinder and dry the grease.
 Do not use in a wet environment.
3.3 Piping
 Before piping make sure to clean up chips, cutting oil, dust etc.
 When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1 thread exposed
on the end of the pipe/fitting.
 Tighten fittings to the specified tightening torque.

3.4 Lubrication
 SMC products have been lubricated for life at manufacture, and do
not require lubrication in service.
 If a lubricant is used in the system, use turbine oil Class 1 (no
additive), ISO VG32. Once lubricant is used in the system, lubrication
must be continued because the original lubricant applied during
manufacturing will be washed away.
3.5 Electrical Connection
 Provide a grounding connection to the actuator to avoid any spark
arising from potential differences.
