Mounting
Caution
4. Auto Switch Mounting
The series MY2 can be equipped with auto switches on the top
of the actuator unit (cylinder) and on the side of the guide unit,
but use caution in the following cases.
<Mounting an auto switch on the top of the actuator unit
(cylinder)>
For auto switches with perpendicular electrical entry, the lead
wire may interfere with the workpiece depending on the
workpiece mounting type and shape.
Be sure to allow a clearance in order to keep the lead wire
from interfering with the workpiece.
5. Workpiece Mounting
When mounting a magnetic workpiece, the auto switch may
stop working due to a loss of magnetic force in the cylinder
depending on the mounting position. Allow a clearance of 5
mm or more between the auto switch and workpiece.
6. Body Mounting
When mounting MY2H40G with stroke adjusting unit from the
top, move the stroke adjusting unit and secure the body with
the end plate mounting holes. After mounting, return the stroke
adjusting unit to the stroke end and secure it again.

7. Do not generate negative pressure in the cylinder tube.
Take precautions under operating conditions in which negative
pressure is generated inside the cylinder by external forces or
inertial forces. Air leakage may occur due to separation of the
seal belt. Do not generate negative pressure in the cylinder by
forcibly moving it with an external force during the trial operation
or dropping it with self-mass under the non-pressure state, etc.
When the negative pressure is generated, slowly move the
cylinder by hand and move the stroke back and forth. After
doing so, if air leakage still occurs, please consult with SMC.
1. Do not apply a strong impact or moment on the
slide table (slider).
Since the slide table (slider) is supported by precision
bearings, do not subject it to strong impact or excessive
moment when mounting workpieces.
2. When connecting to a load which has an external
guide mechanism, use a discrepancy absorption
mechanism.
A mechanically jointed rodless cylinder can be used with a
direct load within the allowable range for each guide type,
however, align carefully when connecting to a load with an
external guide mechanism.
Mount the external guide mounting brackets and floating
brackets in a place where the required degree of freedom for
the floating Y and Z axes can be secured.
The thrust transmission area of the floating bracket must be
fixed so that it does not partially contact the body.
∗
Refer to the Coordinates and Moment in Model Selection on
page 1089 for the details of floating Y and Z axes.
3. Attaching and detaching the actuator unit (cylinder)
When detaching the actuator unit, remove the four cylinder
holding bolts and take the actuator unit off the guide unit.
When attaching the actuator unit, insert the slider into the slide
table on the guide unit, and tighten the four holding bolts
equally. Since loosened holding bolts may cause damage or
malfunction, be sure to secure them tightly.
