Krytox™
PERFORMANCE LUBRICANTS
QC Lubricants carries the following Krytox™ Fluorinated Lubricants in 2 oz tube, 8 oz tube and .5 kg can:
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.
