7.5 Toothed belt tension
Before starting any work on the linear unit, any electric drives used must be prevented
from accidental switching on.
The toothed belt tension is set correctly ex works. A correction is unnecessary in normal
operation.
All toothed belts in linear units need tension, which is required to guarantee safe engaging of the
teeth.
The required pretensioning of the toothed belt must be checked with a pretensioning
measurement appliance.
The specific pre-tensioning values for the different types of linear unit are dependent on
environmental parameters, such as the length of the unit, acceleration and loads to be moved
and can be queried with RK Rose+Krieger GmbH for special cases.
Too high a pre-tension will lead to the toothed belt breaking, bearing overload and
reduction of working life.
Tension the toothed belt with the belt tensioning kit.
Tension the toothed belt 1 by steadily tightening the tensioning screw 2 on the front of the slide
3 clockwise.

The toothed belt of the linear unit must be replaced every 8 years irrespective of the
amount of use and the environmental influences.
