retracted,
•the MCE or MSCE must only be lifted by the cylinder
prole or by the base prole, respectively,
•the MCE or MSCE must never be lifted by the piston rod
or by the slide, respectively, since the ball screw drive is
not self-locking,
•for the case of vertical or inclined positioned product,
the piston rod (of the MCE) or the slide (of the MSCE)
must be secured during transport,
•during carrying, the product must be prevented from
swinging and dropping,
•if the standard motor is preassembled, during
transporting the support of the motor must always be
provided,
•the product weight must be taken into account.

MOUNTING
The piston rod must not be subjected to torsion when
tightening or loosening the hex nut
In order to avoid torsion, use one wrench to hold the
piston rod accessory in proper position, then tighten or
loosen the hex nut with the second wrench, see Figure 9.

Mounting the attachment
Never use other mounting points as it is presented
The attachments can be mounted only on the presented
points (see Figure 11 or 13), otherwise the product may
be damaged.
Avoid from collision of the mounting screws and the
product
There must never be any collision of the mounting
screws and the product, otherwise the product may be
damaged. The length of the mounting screws must be
selected properly.
Avoid from collision of the attachment and the product
There must never be any collision of the mounted
attachment and the product, otherwise the product
may be damaged.
For the mounting holes dimensions of the product and
accessories, please refer to the product catalogue MCE
and MSCE (mini electric cylinders and sliders).
The piston rod must not be subjected to torsion
when tightening or loosening the hex nut
In order to avoid torsion, use one wrench to hold the
piston rod in position, then tighten or loosen the hex
nut with the second wrench, see Figure 12. If the
attachment is fastened on the piston rod end using
the tapped mounting hole, please refer to Figure 9.

MSCE
The attachments can be mounted as follows (see Figure 13):
1 – on the slide
2 – on the front plate
Figure 13: Mounting the attachments to the MSCE.
ORIENTATION
Unexpected movement of the components
Risk of serious injury or even death.
When the product is mounted vertically or in an inclined
position, prevent the piston rod (MCE) or the slide (MSCE)
from dropping due to the no self-locking effect of the ball
screw drive. To avoid dropping of the mentioned moving
components it is recommended to install a suitable motor
with a holding brake.
For the mounting accessories, please refer to the
product catalogue MCE and MSCE (mini electric
cylinders and sliders).
The product can be mounted in any orientation using
a suitable combination of the mounting attachments.

Overloading
Overloading the product can lead to the product being
damaged.
The piston rod must not be subjected to the torsional
loads
The piston rod must not be subjected to the torsional
moment. In the case of the presence of any torsional
loads, the guiding unit might be used, see Figure 14.
In the case of using other external guiding system, the
exactly parallel alignment of the electric cylinder and the
piston rod must be ensured.
Figure 14: Piston rod subjected to the torsional moment Mx.
Figure 15: Warping of the slide.
PERMISSIBLE LOADS
For the values of the maximum permissible axial load,
lateral load, drive torque, travel and rotational speed
and acceleration (of the product and the product
accessories), please refer to the product catalogue
MCE and MSCE (mini electric cylinders and sliders) and
catalogue Stepper systems.
MCE
For mounting the attachment to the piston rod end
in order to avoid torsion, please refer to the section
“Mounting →Mounting the attachment”.
The slide must not be subjected to the loads causing its
warping
The improper mounting of the attachment to the slide can
cause the slide being warped (Figure 15). Service life of the
product can be drastically decreased.
The attachments must always be mounted to the mounting
surface, as it is presented in the Figure 13.
