A low toothed belt pretension is recommended.
Excessive toothed belt pretension can cause:
– impermissible radial loads/breaking of the shafts
– increased wear of the toothed belt 5 and the bearings of the axis and

11. Tightening torques for the toothed belt pulleys
13. Permissible axes and motors
The transmittable torque depends on the tightening torque of the toothed
belt pulleys 6.
 Select the tightening torque of the toothed belt pulley 6 from the
permissible range ( table).
Check: The transmittable torque is greater than the driving torque of the
motor ( technical data of the motor).

Belt failure. Unexpected movement of components.
Injury due to impacts or pinching.
 Make sure there are supplementary safety measures if a belt failure could
result in injuries.
Caution
Hot surface. The motor attachment set becomes hot due to the heat
dissipation of the motor. Injury due to burns.
 Avoid contact without suitable gloves.
 Let the motor attachment set before mounting work.
15. 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 at 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.
