What is the microgel thickener?
Most of the AeroShell range of greases therefore use a patented thickener known as Microgel. This is a specially treated clay based thickener which has: No upper temperature limit (the upper temperature is limited by the base oil) Very little change in consistency with variation in temperature.
Which Type of grease used in aircraft?
Ball bearing greases A synthetic inorganic gel grease, used in low or high temperature applications. Wide temperature performance makes it a preferred grease in jet aircraft. A mineral oil-based, inorganic gel grease, the most common wheel bearing grease used.
What temperature should grease be stored at?
Ideally, grease should be stored in a cool, dry indoor area that does not exceed 86 degrees F (30 degrees C) and remains above 32 degrees F (0 degrees C). It is not unusual to find grease containers in storage areas that have temperatures as high as 130 degrees F (54 degrees C).
What is aviation lubricant?
Typically, engine oils, hydraulic fluids, greases, and special lubricants & additives are the types of aviation lubricants. The piston and turbine engine oils are designed to improve the performance of aircraft engines at extremely high temperatures.
What is aircraft lubricant?
The primary purpose of a lubricant is to reduce friction between moving parts. Because liquid lubricants or oils can be circulated readily, they are used universally in aircraft engines. As long as the oil film remains unbroken, metallic friction is replaced by the internal fluid friction of the lubricant.
How long can grease stay in grease gun?
The expiration date will vary depending on the thickener. For example, lithium grease is often identified as having a 12-month shelf life, while calcium-complex greases may have a shelf life of just six months – and this is under good storage conditions.
CAN expired grease be used?
Risks of using expired lubes While there are no known risks using an old lube, it is not worth the risk. Using an expired lube may cause burning and itching and sometimes the chemicals used in lubes may cause allergic reactions on your skin or might not work well.
