Caution: Exercise caution when installing the actuator horizontally using the optional clevis or
trunnion or any commercially available free joint, because the rod will receive the
actuator weight. As a result, the bush may wear quickly or internal mechanical parts
may be damaged.
If the actuator is installed horizontally using any of the aforementioned means, add a
guide or other appropriate mechanism to prevent the rod from receiving the actuator
weight.
Caution: The optional clevis and trunnion are designed so that the fulcrum shaft can only
receive radial load. In a condition where play is not permitted or thrust load is
received, the customer must design a separate bearing structure.
Caution: The optional clevis and trunnion provide structures whereby the bearing supports the
fulcrum shaft. Apply grease to the fulcrum shaft.
