SAE AIR1594A

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 is given on bearing installation methods and fits that have given satisfactory performance and service life expectancy.Corrosion is a major cause of problems in bearing installations for landing gears. Therefore, methods of corrosion prevention are outlined.Effort is directed toward minimizing maintenance and maximizing life expectancy of bearing installations. Lubricated and self-lubricating bearings are 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 his 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.
