LANDING GEAR AND STRUT FLUID
ROYCO LGF is a mineral oil based hydraulic fluid designed
specifically for use in aircraft landing gear systems shock struts and
other fluid dampening systems. Modern additive technology for greatly
improved lubricity and extreme pressure antiwear performance is used to
provide the performance levels required by today’s wide body aircraft.

ROYCO LGF was specifically developed to improve “slip
stiction” and to alleviate “ladder cracking” in landing gear struts due to
sudden and severe shock loads encountered in these aircraft during
ROYCO LGF is approved for use in most current models of
Boeing, Lockheed, McDonnell
Douglas, Airbus, and many other manufacturers of commercial transports.
ROYCO LGF is qualified to Boeing Materials Specification
BMS 3-32 (Type II) it also conforms to Douglas Specification
