Q: Are the 13889 Timken bearings the FAA PMA'd bearings or the automotive ones? Blue box / FAA certified?
The 13889 bearings are PMA approved for aircraft use. They will ship in the blue box.
Q: I found 07100 bearing so in my Maule TW102 taillwheel .... are the 13889 bearings the correct FAA-PMA version of that bearing?
You will want to use Part # 08-12292 for the bearing on the TW102 tailwheel.
Q: Do you have the cup and bearing sold together?
It is commonly sold with the 13836 cup, but you would need to check your application to make sure that is the cup required. We do not offer it as a kit, each piece must be ordered separately.
