What is AeroShell Grease 33?
AeroShell Grease 33 is a synthetic universal airframe grease composed of a lithium complex thickened synthetic base oil with corrosion and oxidation inhibitors and load carrying additives. The useful operating temperature range is –730C to +1210C.
What is the shelf life for AeroShell Grease 33?
Aeroshell Grease 33 is specifically designed to lubricate a wide range of applications and operating conditions on commercial aircraft. Meets BMS 3-33B and MIL-G-23827 and covers the operating temp of -100 to 250 F. Shelf life 2190 days.
What is moly in Grease?
Molybdenum Disulfide, simply known as Moly, is used both independently as a dry lubricant and as an additive in lubricating greases. Dry lubricants reduce friction between two sliding surfaces without the need for an oil medium.
Does aeroshell grease expire?
The Certificate of Analysis will be reflected to state: “Shelf life of AeroShell Grease is 6 years from the date of manufacture. The validity of shelf life is based on the container remaining unopened, undamaged and stored under shelter at constant ambient temperature condition.
Does Aviation oil go bad?
The answer is fairly easy from a legal standpoint because the Military and SAE specifications state that the supplier must guarantee that the product stay within spec for at least three years. So, if you are a commercial operator or lubricant sales organization, the shelf life is three years.
Why was moly in grease?
The Moly particles are intended to fill in tiny imperfections in the machined surfaces and protect against “welding” during shock loading and heavy loads; however, the material is also known to stick to surfaces and cause a coating to build up. There are a few different explanations for why Moly is used in greases.
What does EP stand for in grease?
extreme pressure
The term EP refers to extreme pressure, which means the grease is formulated with additives that increase its load carrying capacity.
Does lubricating oil go bad?
Normal Shelf Life: In general, the recommended shelf life for oils and greases is typically five years when stored properly in the original sealed containers. Industrial and automotive oils may show deterioration by one or more of the following: • Cloudy appearance or strong odor.
Does Grease deteriorate with age?
Most materials including lubricating oils and greases deteriorate with time. The art of good storage practice is to always have materials available when required, and to ensure stock turnover so that lubricants are used before any significant performance loss has occurred.
How long will engine oil last in a sealed container?
about 2-5 years
Motor oil stays good in the oil bottle until its expiry date when unopened. This will give you about 2-5 years before unused oil becomes unfit for consumption.
What does LM stand for in grease?
Lithium grease is the most commonly used lubricating grease around the globe – accounting for 75% of lubricating applications across all industries. In the automotive industry it is commonly used as a lubricant in wheel bearing and chassis applications.
What is aeroshell grease 33ms?
AeroShell Grease 33MS is an extreme pressure (EP) grease based on the proven lithium complex technology of AeroShell Grease 33, and is fortified with 5% Molybdenum Disulphide.
What is BMS 3-33 grease?
Boeing, in developing their BMS 3-33 specification, took account of the properties of the different grease types used on aircraft and wrote a specification for a grease which would provide improved performance and which could be used in the widest possible range of grease applications.
How water resistant is aeroshell grease?
Through a water washout test, the water resistance of each grease was assessed. AeroShell Grease 33 recorded the lowest percentage of weight lost, showing performance nearly twice as that of our competitors, which is important to ensure the grease stays in place in wet conditions and protects your aircraft
What are the advantages of using a single Grease?
Replacing several greases with a single grease avoids the risk of misapplication and also reduces stock inventory, again providing cost savings. Useful temperature range is -73°C to +121°C. AeroShell Grease 64 is an EP airframe grease based on the proven lithium thickener technology of AeroShell Grease 33.
