Load restrictions
Provided that a dynamic load is not generated, a load in the axial direction can be applied up to the value
that is indicated in the table (5) below. However, applications in which the load is applied directly to the
shaft should be avoided as much as possible.
Table 5.
Allowable shaft load
The methods such as those described below are recommended to prevent the load from being applied
Directly to the shaft in order to ensure a proper operating condition.
Operation of shaft couplings
As in Fig. (3), alignment of the rotary actuator and the mating axis is necessary when the rotary actuator
Is used with its axis lengthened, If misaligned, 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.
