Description

Krytox 240AD Aerospace & Aviation Grease 5 Gallon / 20 kg Pail

Krytox 240AD is the highest viscosity grease in the 240 series. With a viscosity of 1540 at 20°C and a viscosity of 502 at 38°C it is ideal for applications that require a thick grease. This grease does not meet the MIL SPEC.

Krytox 240AD Aerospace & Aviation Grease

Applications for Krytox 240AD lubricants are generally of a critical nature with temperatures in all industries reaching extremes for conventional lubricants. They are expected to be durable in the most aggressive environments and are now often considered an integral part of the design. Where failure of components is not an option, whether because of durability, warranty, safety, loss of productivity or down time, Krytox is the lubricant of choice in a wide range of industries and applications.

In the aerospace industry, Krytox 240AD grease is applied in various settings spanning from bearings and sealants to o-rings and oxygen systems. Krytox is a valuable asset to the aerospace industry due to its superior performance in a wide range of temperatures scaling from 70 to 399ºC (–100 to 750 ºF). In addition, it is robust in harsh environments and has excellent frictional properties, allowing it to resist change in properties over time, provide longer wear, and lower energy consumption. Krytox lubricants are compatible with all metals, elastomers, plastics, paints, and finishes. Due to the intense and severe circumstance of the aerospace industry, it can be expected that Krytox delivers a high level of product excellence.

Specialty Lubrication the Aerospace Industry – Highest Viscosity in the 240 Series

New bearings and equipment that are not lubricated often have rust preventive oils in them to prevent damage while they are in storage before use. New bearings should be inspected for damage and cleanliness before use. The greases or preservative oils need to be removed when using Krytox as a lubricant. Failure to do so could result in reduced bearing life. Bearing life tests on uncleaned bearings have shown reduced life in high temperature, high-speed tests where the bearing was filled with a minimum amount of grease. The preservatives coat the metal surface to prevent rusting so they can also prevent the grease from adhering, causing them to be thrown off by the action of the bearing. They also will oxidize and harden and can create debris which will contaminate the grease.
