(5) Using screws on a clevis (optional)
An optional clevis is available for installing the actuator. Use this clevis, if necessary.
z Applicable models: Motor reversing type RCA-RA3R, RCA-RA4R
Mating material is steel Mating material is aluminum
Screw size M8 M8
Tightening torque 30 N•m 12 N•m
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.
y The optional Clevis or Trunnion has the structure that the bearing selects the fulcrum
shaft. Apply grease onto the fulcrum shaft.
