18.0 Grease & Hydraulic Oil Specification
In general, there is no need to lubricate the actuator because
its mechanism is lubricated for life. The standard grease
for Rotork fluid powered actuators is shown below. If an
alternative was specified and/or supplied, please refer to the
job specific documentation.
