Oil Specification
The FTX and FTP Series use Mobil SHC 626 for oil fill. The actuator is
shipped empty and only receives a light oil coating from the factory for
initial test. The actuator must be filled by the customer for their specific
application. The case features integrated sight glasses and sight tubing
to ensure a proper oil fill level depending upon the orientation of the
actuator. Slight foaming of the oil in operation is normal and is a result of
the initial coating of grease from the bearings.
