Running ROYCO 27
APPLICATIONS:
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-PRF-23827 are specified.
ADVANTAGES:
• Designed for high loads and high speed bearings • Wide operating temperature range• Rust and corrosion protection • Thermal and oxidative resistance
APPROVALS:
ROYCO 27 meets all requirements and is qualified against MILSPEC: MIL-PRF-23827C.
The synthetic oils used in ROYCO 27 may soften natural rubbers, neoprene, some types of electrical insulating compounds, and certain paints.
