Lubrication:
None required
Norgren Rotary Actuators are rated
for "no lube added" service. All
internal components are lubricated
at the time of assembly with a
PTFE based grease. Should
additional lubrication become
necessary between the radial
surface of the rack gear and the
rack/pinion mesh area due to
severe operating conditions, a
grease fitting is provided.
