ROYCO LGF is a mineral oil based hydraulic fluids 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 anti-wear performance is used to provide the performance levels required by today's wide body aircraft. 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 consists of hydraulic fluid conforming to MIL-H-5606 plus LUBRIZOL 1395 and other additives to improve landing gear performance.
ROYCO LGF is completely compatible with oils meeting MIL-PRF-5606 and MIL-PRF-6083. ROYCO LGF is specifically developed to improve "slip stiction" and to alleviate "ladder cracking" in landing gear struts due to sudden and severe shock loads encountered during landing.
