5-3 External stopper
When kinetic energy generating the load exceeds the rotary actuator allowable kinetic energy, the inertia
force has to be adsorbed by externally installed cushioning function.
5-3-1 Install position of external stopper
External stopper lead to cause the rotary actuator axis torsion, damage and the breakage of the axis
bearing depending on install location of stopper and load shape and the place.
Place an external stopper in apposition that is away from the rotary actuator or the material point.
5-3-2 Caution on using external stopper
Angle adjustment is available for CRQ2 series rotary actuator. Mind so that the hexagon socket set screw
(angle adjusting screw) does not collide into the piston.

External stopper acts as
fulcrum. Load inertia force is
applied to the shaft as
bending moment
Inertia force generated by
the load
is directly applied
to the axis if the external
stopper on the opposite side
of the load.
