Caution: y When the optional Clevis, Trunnion or commercially available free joint is attached

and the actuator is installed horizontally, take the greatest care because the weight

of the actuator is given to the rod. Otherwise, the bush might be worn out earlier or

inside mechanism might be damaged.

Add the guide mechanism, etc., so that the weight of the actuator is not given to the

rod.

y

For the load given to the optional Clevis or Trunnion fulcrum shaft, only the radial

load is allowed. In the case of the conditions that the backlash is not allowed or thrust

load is given, the user should design the bearing structure.

shaft. Apply grease onto the fulcrum shaft.
