２．Actuating force and moment
2-1) Actuating force
The actuating force of rodless cylinder is ideally equal to
thrust at center of axis of piston but normally, as shown on
Fig. 7-1, it is taken as FnN at the part away from the center
by Locm.
The relationship between Lo and Fn can be figured from Fig. 7-2.
Sizing
Ex) Sliding resistance of load：100N
Distance between center of axis
and point of application：8cm
Fig. 7-2 Relationship between Lo and Fn
In each graph, find the point where 8 of X axis crosses
with 100 of Y axis. If the point is covered with applicable
operating range of the graph, the size making the graph
is applicable to exampled requirements. In this case,
CY3R32 or larger are applicable.
