Castrol® Aeroplex AI is a smooth, buttery, light brown grease with exceptionally good low and high temperature properties. It consists of a synthetic
ester base stock, inorganic thickener, and additives which impart resistance to oxidation and moisture and which improve load carrying capacity under extreme pressures.
-100°F to 250°F (-73°C to 121°C); and for short periods to 300°F (149°C).
Castrol® Aeroplex AI is intended for general use in ball, roller and needle bearings, gears and on sliding and rolling surfaces of equipment, such as
instruments, cameras, electronic gear, and aircraft control systems. It is particularly suitable for equipment, which must operate at both low and high
temperatures. Its extremely low volatility helps prevent oil fogging in optical instruments. Castrol® Aeroplex AI is also excellent for general use
on aircraft gears, actuator screws, and other equipment requiring a lubricant with high load carrying capacity.
The synthetic oils used in this grease may soften paint, natural rubber, neoprene and electrical insulating compounds. Customers should determine the
compatibility of existing components with ester based grease and make any changes as required prior to use of this product.
