– Clean shafts. The clamping sleeves only grip efficiently on dry and grease-free
drive shafts.
– Perform a homing procedure each time after disconnecting or turning the
motor.
– Select required mounting components. The kit contains all the mounting com-
ponents that may be required.
– Observe tightening torques. Unless otherwise specified, the tolerance
is±20%. è 8 Technical data.

5 Mounting
5.1 Mounting the housing
Fig. 6 Place centring ring
• Press the centring ring[30] into the drilled hole in the housing[1].
Fig. 7 Fasten axis
• Fasten axis to the housing[10] with the screws[1].
With EAMM-U-...
Fig. 8 Attach motor - without adapter plate
• Attach the motor with the screws[2] and the square nuts[9] to the
housing[1].
ÄThe motor is movable and can be easily tilted.
For EAMM-U-...-42A the mounting direction is different.
• Attach the housing[1] to the motor with the screws[2].
With EAMM-U-...-67A an adapter plate[40] is required.
• Please note the following section.
With EAMM-U-...-67A
Fig. 9 Attach motor - with adapter plate
1. Fasten the adapter plate[40] to the motor with the screws[2].
2. Attach housing[1] to the adapter plate[41] with the screws[40].
ÄThe motor is movable and can be easily tilted.
5.2 Mounting the toothed belt
Fig. 10 Insert toothed belt
1. Grease the clamping sleeves[3]/[4] and the outside of the cone with lubricat-
ing grease[60].
ÄGreased clamping sleeves[3]/[4] can be tightened evenly.
2. Screw the clamping sleeves[3]/[4] into the thread of the toothed belt
pulleys[6]. Do not tighten.
3. Insert the toothed belt pulleys[6] into the toothed belt[5].
4. Move the motor in the direction of the axis up to the stop and tilt it slightly.
5. Place the clamping sleeves[3]/[4] on the drive shaft.
6. Fasten motor with the screws[2]/[41].
ÄThe motor is movable, but it can no longer be tilted.
Fig. 11 Aligning toothed belt pulleys
• Position surfaces[A] approx. 1 mm above the reference surface[B].
ÄBackground: The tooth belt pulley[6] moves inwards when tightening.
The position of the surface[A] depends on the size.
Fig. 12 Area A on the toothed belt pulley
Fig. 13 Tighten toothed belt pulleys
1. Select the required tightening torque for the toothed belt pulleys[6]
è 8.2 Tightening torques for the toothed belt pulleys.
2. Tighten toothed belt pulleys[6]. Apply counter pressure to the clamping
sleeves[3]/[4].

Fig. 14 Observe tolerances
1. Observe tolerances. The areas[A] must be flush with the reference area[B].
Tolerance: ± 0.5mm
2. If the toothed belt[5] or one of the toothed belt pulleys[6] is grinding against
the housing:
– Unscrew clamping sleeves[3]/[4] slightly.
– Readjust the toothed belt pulleys[6].
5.3 Mounting the counter bearings
NOTICE!
When counter bearings are installed, they extend the service life of the axes and
motors.
• Always mount the counter bearing[32] included in the scope of delivery.
• With heavy loads: mount optional counter bearingEAMG-U1
èwww.festo.com/catalogue.
NOTICE!
Malfunctions and material damage may occur if the trunnion[F] is bent.
• When tightening the toothed belt pulley[6], avoid a transverse load of the
trunnion[F] on the clamping sleeve[31].
Prerequisite: The toothed belt fitted with clamping sleeves[31] and [4] mounted
but not yet tensioned.è 5.2 Mounting the toothed belt.
Fig. 15 Fasten counter bearing
1. Push the needle bush[G] onto the trunnion[F] of the clamping sleeve[31]
avoiding tension.
2. Fasten the counter bearing[32] with the screw[33] on the thread[H].
3. Tension toothed belt[5].
With EAMM-U-110/-145: Fasten counter bearing[32] with 2 screws[33].
5.4 Tensioning the toothed belt
NOTICE!
Toothed belt pretensioning too high.
Impermissible radial loads or shaft break.
Increased wear of the toothed belt and the bearings of axis and motor.
• Avoid excessive toothed belt pretension.
A low toothed belt pretension is recommended.
The toothed belt[5] is tensioned when the strands[D] run approximately parallel:
–Untensioned: y>x
– Tensioned: yL1…1.05x
