Krytox greases:
Krytox greases are based on perfluoropolyether (PFPE)
oils. These synthetic fluorinated lubricants are used in extreme conditions such
as continuous high temperatures up to 300 °C (572 °F) and higher temperatures
for shorter periods, depending on product grade limits.
Chemically inert and safe for use around hazardous chemicals,
these lubricants are nonflammable and are safe for use in oxygen service. Krytox
oils and greases are silicone free and do not damage plastics or elastomers or
cause corrosion to metals. They are commonly used as lubricants in aerospace,
automotive, industrial and semiconductor applications as well as solving many
other routine lubrication problems.
Krytox greases are the original products that this military specification was
written for and have been certified continuously since the specification was
originally written. This is the latest data from the recertification that is
required every five years. Krytox greases are standard as NLGI Grade 2
penetration. If the 240 AZ is ordered to meet MIL-SPEC requirements, it must be
ordered as NLGI Grade 1 to meet the specification.
KRYTOX Typical Applications:
Krytox lubricants are generally of a critical nature with temperatures in all
industries reaching extremes for conventional lubricants. Krytox lubricants 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 oils and greases are applied on 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 399 ºC (–100 to
750 ºF). In addition, Krytox 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.
Preparation Before Packing Bearings With Grease:
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 unclean 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.
Packaging:
Krytox greases are available in 2 oz and 8 oz tubes; 0.5 kg; 0.8 kg and 1.75 lb cartridges.
Storage and Shelf Life
Krytox grease and oil lubricants have a shelf life of 10 years.
