8. Caution for Operation�
8.1 Load Applied to Actuator
� RCD-RA1D actuator cannot accept the load from sides (radial load) or rotation torque. Applying these types of
load may cause an operation failure, breakage of components or shortened life. Use a device such as the
external guide.
� Pay attention to the reaction force so it would not become the load from a side. Utilize a guide so it receives the
side load.
Pay attention to the direction of the reaction force.
� When joining a work piece guided by an external guide with the rod, pay attention to the difference in the
moving directions of the external guide and the rod (traveling parallelism). Use a free joint that gives a freedom
to the joint of the work piece and the rod to eliminate the variance in the attachment and the difference in the
moving direction. Not using it may cause a generation of abnormal noise or shortened product life.
External guide Free Joint
Work
� Be careful not to apply a huge load on the side of the rod due to the attaching variance when joining a guide to
the work piece.
