reases play a vital role in aviation applications.
They protect critical components, such as wheel
bearings, landing gear bearings, slides and joints
from corrosion, extreme temperatures, heavy loads,
rain, and rust.
Strict aviation regulations and mandatory OEM
approvals help segment grease types by specifica-
tion and ensure that operators use only greases
that are specifically approved for their intended
aircraft applications.
However, having common specification approvals
does not mean that all greases perform similarly. In
fact, typically, they do not. Since greases can have
different formulations, it's no surprise that they do
not perform exactly the same.
That's why choosing the right greases and hav-
ing the right lubricant partner is a great way for
airline operators to help maximize the efficiency
and effectiveness of their maintenance programs.
SO WHAT IS THE RIGHT APPROACH TO
GREASE SELECTION AND USE?
For many operators around the world, a successful
grease lubrication approach usually includes the use
of a few select greases that deliver proven value
and effectiveness to the user.
A common scenario is for an airline operator to
use a high-performance, multipurpose grease like
Mobilgrease 33, which has a long shelf life, along
with a specific application grease like Mobil Aviation
Grease SHC 100, in their wheel bearings, due to its
bearing rejection rate statistics.
HOW TO MAXIMIZE MAINTENANCE EFFICIENCY
THROUGH PROPER GREASE SELECTION
A multipurpose grease can deliver outstanding protection against
wear and rust and extend the life of bearings and components
