ROYCO 27 is a light tan colored synthetic ester based grease with a lithium stearate thickener. Additives are provided for oxidation and corrosion resistance as well as rust protection and extreme pressure anti-wear properties.
ROYCO 27 is intended for use in highly loaded gears and actuators as well as instruments and high-speed bearings over temperatures from -100 to 275oF. In addition, ROYCO 27 may be used in all applications where MIL-G-3278, MIL-G-7118, MIL-G-7421, MIL-G-15793, and MIL-G-23827 are specified.
• Designed for high loads and high speed bearings
• Wide operating temperature range
• Rust and corrosion protection
• Thermal and oxidative resistance
The synthetic oils used in ROYCO 27 may soften natural rubbers, neoprene, some types of electrical insulating compounds, and certain paints.
ROYCO 27 meets all requirements and is qualified against MILSPEC: MIL-PRF-23827C.
