This document is intended to give advisory information for the selection of plain bearings and bearing materials most
suitable for aircraft landing gear applications. Information included herein was derived from bearing tests and service
experience/reports. Airframe/landing gear manufacturers, commercial airlines, the U.S. Air Force and Naval Air
Systems Command provided input for the document.
Information is given on bearing installation methods and fits that have given satisfactory performance and service life.
Base metal corrosion is a major cause of problems in bearing installations for landing gears. Therefore, methods of
corrosion prevention are discussed.
Effort is directed toward minimizing maintenance and maximizing life expectancy of landing gear bearings. Lubricated and
self-lubricating bearings are also discussed.
There are wide ranges of bearing load and motion requirements for applications in aircraft landing gears. For this reason,
it is the responsibility of the designer to select that information which pertains to the particular application.
Anti-friction bearings, defined as rolling element bearings generally used in wheel and live axle applications, will not be
discussed in this document.
Landing gear shock strut bearing design and selection criteria are covered in AIR5883 and, therefore, are not discussed
in detail in this document.
1.1 Purpose
This document is to be used as a general reference for the aerospace community.strRefField
