AQSh harbiy samolyotlari ishonchli, bardoshli va samarali bo'lishi kerak bo'lgan muhim komponentlarni talab qiladi. Samolyotning asosiy qismlaridan biri aylanuvchi qismlar uchun silliq va izchil harakatni ta'minlaydigan podshipniklardir. Samolyotlarda ularning qo'llanilishi va talablariga qarab har xil turdagi podshipniklar qo'llaniladi. Odatda, samolyot podshipniklari haddan tashqari haroratlar, yuqori yuklar va tezliklar va korroziy muhitda ishlash uchun mo'ljallangan.
Harbiy samolyotlarda eng ko'p ishlatiladigan rulmanlardan biri ichki va tashqi poygalar o'rtasida bir nechta harakatlanuvchi to'plarni o'z ichiga olgan rulmandir. Bilyali rulmanlar yuqori tezlik va yuklarga bardosh bera oladi va radial va eksenel kuchlarni uzatadi. Ushbu rulmanlar odatda dvigatel, vites qutisi va yordamchi quvvat bloklarida qo'llaniladi.
Harbiy samolyotlar uchun mos bo'lgan yana bir turdagi rulman rulmandir. Nomidan ko'rinib turibdiki, rulmanli rulmanlar harakatni uzatish uchun to'plar o'rniga silindrsimon roliklardan foydalanadi. Rolikli rulmanlar yuqori yuklarni ko'tarishi va yuqori radial va eksenel kuch uzatishni ta'minlashi mumkin. Ushbu rulmanlar odatda qo'nish moslamalari tizimlarida, boshqaruv sirtlarida va uzatish tizimlarida qo'llaniladi.
Konik rulmanlar harbiy samolyotlarda ham keng qo'llaniladi. Ular konusli roliklarga ega va yuqori radial va eksenel yuk ko'tarish qobiliyatini ta'minlaydi. Konik rulmanlar odatda dvigatel, vites qutisi va vertolyot rotor tizimlarida qo'llaniladi.
Ushbu turdagi rulmanlarga qo'shimcha ravishda, ba'zi samolyotlar sferik rulmanlar, jurnal rulmanlari va rulmanlar kabi maxsus rulmanlarni talab qiladi. Sferik rulmanlar o'z-o'zidan tekislanadigan podshipniklar bo'lib, qanotlarni boshqarish yuzalarida va qo'nish moslamalari tizimlarida qo'llaniladi. Jurnal rulmanlari radial yuklarni qo'llab-quvvatlaydi va yuqori harorat va tezliklarga bardosh berishga mo'ljallangan. Pompalar eksenel kuchlarni tashish uchun mo'ljallangan va odatda dvigatellar va transmissiyalarda qo'llaniladi.
Umuman olganda, AQSh harbiy samolyotlarida qo'llaniladigan podshipniklar qat'iy sifat standartlariga javob berishi va foydalanishga ruxsat berishdan oldin qattiq sinov va sertifikatlash tartib-qoidalaridan o'tishi kerak. Ushbu podshipniklar harbiy samolyotlarning xavfsizligi, ishonchliligi va samaradorligini ta'minlashda muhim rol o'ynaydi.
