Jednoradové guľkové ložiská s kosouhlým stykom majú obežné dráhy v takej polohe, že spojnica ich stykových bodov s guľkami zviera s kolmicou na os ložiska ostrý, tzv. stykový uhol.
Ložiská vo vyhotovení B majú stykový uhoľ α = 40° a veľký počet guliek s dobrým primknutím, čo zaručuje ich vysokú únosnosť.
Môžu zachytávať radiálne zaťaženia, pôsobiace súčasne s relatívne veľkými axiálnymi silami v jednom smere. Z toho dôvodu sa montujú spravidla dve ložiská proti sebe, čím sa dosiahne axiálne vedenie v obidvoch smeroch.
Jednoradové guľkové ložiská s kosouhlým stykom vo vyhotovení AA majú stykový uhol α = 26° sú určené pre uloženia s relatívne väčším axiálnym zaťažením.
Ložiská vo vyhotovení B a AA sú nerozoberateľné, hoci majú na obidvoch krúžkoch iba jeden nákružok.
