Awood u leh inuu u adkaysto culeysyada shucaaca;
Awood u leh inuu u adkaysto culeysyada axial ee laba jiho;
nooca
Dekadaha xirxiran ee xajiyeyaasha 7000C (x=15), 7000AC (x=25), iyo 7000B (x=40) waxay ku yaalaan giraanta dibadda.Guud ahaan, giraanta gudaha iyo dibadda lama kala saari karo waxayna u adkeysan karaan culeysyada radial iyo axial iyo sidoo kale culeysyada axial ee hal dhinac.Awoodda u adkeysiga culeysyada axial waxaa lagu go'aamiyaa xagasha xiriirka, iyo xagasha weyn ee xiriirka waxay keentaa awood sare oo ay u adkeyso culeysyada axial.Nooca noocaan ah wuxuu xaddidi karaa barokaca axial ee shafka ama qolofka hal jiho.
