4-1 Restriction of the load to axis
Table of load below shows the allowable load when no moving load applied to axis direction. Avoid
applying load to the axis directly as much as possible.
Although allowable radial, thrust load can be applied where no moving load exist, direct load to the axis
should be avoided as much as possible. Example below is recommended so that the load is not applied to
the axis directly.
4-2 Operation of axis fitting referring
As in Fig.5, alignment of the rotary actuator and the mating axis is necessary when the rotary actuator is
used with its axis lengthened. If misaligned, partial load becomes high and the axis is applied with
excessive bend moment. Under this condition, stable operation is not available which lead to cause the
damage of axis. In this case, flexible fitting (flexible joint specified by JIS) becomes necessary.
