Maximum load
In the case of shock load applications, the figures given in the diagrams above must be reduced by a factor of 2.
Maximum load capacity is dependent on the outstroke of a horizont ally installed
guide unit. In the case of short stroke operation, the load capacity figures taken
from the diagram must be multiplied by the correction factor (diagram 2).
In the load capacity graph (diagram 1), the short stroke corrections have already
been taken into account for anoutstroke > 60 mm

The total deflection of guide rods will be determined by the addition of that due to
own weight (diagram 3) and that due to load capacity (diagram 4).
