4.0 Structure and function
4.1 Brief description
The CASM (⮑ Fig. 1) is a linear actuator designed to work in
factory automation. The drive is used exclusively for dy-
namic center compression or traction movement.
The linear unit (7) is powered through a coupling (5) by a mo-
tor (6). The motor (6), in direct drive, drives either a trapezoi-
dal or a ball screw system. Via the screw mount, the trape-
zoidal screw or ball screw system transforms the rotation of
the motor (6) into a linear motion of the actuator (8).
The rod leads and the other accessories transmit the actua-
tor power in the application.

NOTE
The relevant seal must always be tted between all components
to ensure the requisite degree of IP protection.
Fig.9
NOTE
For the following steps, check the required screw size and the
tightening torques using the values indicated in the table 2.
Step 1
Mount the coupling housing (K) to the linear unit (LE) by in-
serting the square seal with the cut-out (D1) between the
two components and tightening the housing using four Allen
screws (S1). (⮑ Foot mounting option 7.5.5.1)
Step 2
Mount the motor ange (MF) to the coupling housing (K) by
inserting the circular seal (D2) in between them. Make sure
that the coupling is positioned according to table 4 for the
conguration without the foot mounting kit or table 5 when
using the foot mounting kit. Tighten the screws (S2) accord-
ing to table 2.
Step 3
Mount the motor ange (MF) to the motor (M) by inserting
the seal (D3) in between and using the four screws (S3)
(g. 9) to nish the installation.

CASM parallel kit
7.4.1 Use as intended
The adapter kit allows a parallel motor mounting (⮑ 7.4.2
Recommended motors, page 19) to a CASM linear unit.
7.4. 2 Recommended motors
In principle, all motors that are equipped with an smooth
shaft may be tted. It is important that the rated torque and
speed of the motors does not exceed the permitted values
of the linear unit. Detailed information may be found in the
technical notes relating to the electric cylinders. Ewellix rec-
ommends the following SIEMENS 1FK7 servo motors:
(⮑ table 1).

Intermediate plate installation
Fig.11
Step 1
Mount the motor (M) on the intermediate plate (ZW) by in-
serting the square seal without cut-out (D1) in between and
tightening it using all the Allen screws (S3). When assem-
bling, note the alignment of the intermediate plate marking (X).
Step 2
Attach the linear unit (LE) to the intermediate plate (ZW), in-
sert the square seal with cut-out (D2) and hand tighten the
four screws (SB).
NOTE
Do not tighten the screws (SB) until step 5 chapter 7.4.4.
7.4.4 Timing belt installation
Fig. 12
Step 1
Push the linear unit (LE) as far as possible towards the mo-
tor (M) and tighten the screws (SB) by hand.
Place the two clamping sleeves (CS) on the shaft of the lin-
ear unit and the motor. Take the timing belt and insert the
pulleys (P/PF).
Step 2
Push the pulleys over the clamping sleeves. The anged pul-
ley (PF) has to be on the shaft of the linear unit. Push the
anged pulley and clamping sleeve as far as possible on the
screw trunnion and align the pulley (P) and the 2nd clamping
sleeve on the motor side as follows:
• CASM-32: Push the pulley as far as possible
• CASM-40/63: Position the pulley by placing the assembly
tool (MH) on the intermediate plate and pushing the pulley
as far as possible.
Step 3
Secure the pulley by tightening the nut (torque as per table 3)
and countering at the same time with a hexagonal wrench.

CASM– 40 –1FK7022 GT3–3M–Z24 20 Nm
CASM–63–1FK7034 GT3–5M–Z22 40 Nm
Step 4
Place the central pretension screw (SP) in the side bore of
the intermediate plate (ZW, g.12) and tighten the timing belt
(Z) using the pretension screw (SP).
NOTE
Loosen the special screw (SB, g. 11) if the belt cannot be
tightened.
Step 5
Measure the timing belt tension using a suitable frequency
measurement device. Adjust the pretension screw (SP) until
the required belt tension is reached and tighten the screws
(SB) according to table 2.
Tightening the pretension screw (SP) increases the natural
frequency of the timing belt (table 4). Excessive preloads
can lead to increased wear in the bearing of the linear unit
(LE) or motor (M) due to radial loading. Once the correct fre-
quency is set, secure the special screws (SB) and check the
timing belt frequency again.
