DESCRIPTION:
ROYCO 45 is an inorganic gel-thickened mineral oil based grease compounded with high load carrying ability
and additives to provide excellent resistance to water as well as high temperatures. Modern additives are
included to protect against rust, oxidation/corrosion, and to provide lubrication in severe operating
environments. This product has a useful temperature range of -20°C to 190°C.
.
APPLICATIONS:
ROYCO 45 is intended for use in anti-friction bearings where water resistance is desired. This grease has
demonstrated superior performance in aircraft and heavy-duty truck wheel bearings as well as off road and
agricultural equipment. ROYCO 45 has also been used in the lubrication of aircraft engine accessories and
controls operating at temperatures as high as 190°C.
