External stopper

If the kinetic energy that is generated by the load exceeds the actuator’s threshold value, an external
dampening function must be provided to absorb the energy.

Mounting position of external stopper

Installing the stopper near to the centre of the table should be avoided.
When the rotation arm strikes the stopper, a reaction force generated by the load’s inertia will be
redirected and applied to the table itself.
This will lead to damage to the table and bearings.

* Caution for using external stopper

Angle adjustment is available for MSQ series rotary actuator. When using an external stopper, set in a
position so that that the adjusting bolt does not collide into the piston.

- 35 -

Fig. 14

Install the stopper at a
sufficient distance from
the table centre.

The  external  stopper
becomes  a  fulcrum,
resulting  in  the  load’s
inertia

force

being

applied to the table as
a bending moment.

If  an  external  stopper  is
installed  on  the  opposite
side  to  the  load,  the
inertia force generated by
the  load  is  applied
directly to the pinion.
