7.2 Installation
7.2.1 General
•
Before installation, the corrosion protection at the shaft ends of linear units with drives must
be removed.
•
No cleaning agents must enter the bearing.
•
When installing transfer components such as clutches or motor adapters, blows to the shaft
ends or impacts to the drive pins must be avoided, in order to prevent the bearing becoming
damaged or unbalanced.
•
The linear unit must be secured on a level surface with a minimum accuracy of 0.20 mm/m
•
The linear unit must not be tensioned during installation.
•
For operations, sufficient fixing points are to be chosen between the linear unit and the base.
•
Loads to be moved by the linear unit must be correct and secured adequately for the applica-
tion.
•
The high intrinsic weight of components and the linear unit generates dangers for persons
and property.
•
When installing a motor on the linear unit, you must take care to align its motor shaft and
drive shaft axially.
7.2.2 Torques
Torque guideline values for metric shaft screws to DIN 4762 at 90% use of the 0.2% expansion
limit, for a coefficient of friction of 0.14.
