When counter bearings are installed they enhance the service life of the axes and motors. Always install the counter bearings cB that are included in the scope of de-
livery.
An optional installation of the counter bearings is recommended for high loads ( www.festo.com/catalogue: EAMG-U1).
16335d_13
Mount the components ( section 5):
– Toothed belt 5 – Toothed belt pulleys 6 – Clamping sleeves cA/cC.

Information
Accessories for mounting on the threads (I): ( www.festo.com/catalogue: EAMM-U-...-D...-...B/C/G/H-S1).
Caution
Screws aJ can break off in the housing. Injury due to uncontrolled movement of components. For EAMM-U-145 and mounting accessories on the threads (I): Limit the feed forces of the axis: – maximum 13 kN in the event of a dynamic tensile load – maximum 11 kN in the event of an alternating tensile/pressure load.
10. Tightening torques for the toothed belt pulleys
The transferable torque depends on the tightening torque of the toothed belt pulleys 6. Select the tightening torque for the toothed belt pulley 6 from the per-
missible range ( table). Check: The transferable torque is greater than the driving torque of the motor ( Technical data of the motor).

Note
Malfunction and material damage due to overloading. The output variables of the motor must not exceed the permissible technical data of the components used ( www.festo.com/catalogue: Motor, gear unit, axis). Limit motor output variables accordingly.
Derive the axis and motor from the interface code in the type designation.

14. Maintenance The toothed belt 5 is a wearing part ( www.festo.com/spareparts). Check the toothed belt 5 at regular intervals: – during maintenance of the machine – when replacing an axis.
Replace the toothed belt 5 if it exhibits any of the following signs of wear: – excessive accumulation of wear particles in the housing – cracks on the back of the toothed belt – visible glass fibre cords in the tooth base.
Caution
Screws aJ can break off in the housing. Injury due to uncontrolled movement of components. When using the ESBF axis in a high load range (, 50 % of the maximum ESBF feed force) and mounting accessories on the threads (I): Replace the axis and parallel kit at the same time.
The service life of the components is comparable with one another.
