1. Zimbalangondo ziwiri ndizofanana ndipo zimayikidwa mbali imodzi;
2. Imatha kupirira katundu wozungulira;
3. Kulephera kusintha pakati pa mphamvu yokoka pang'ono ndi kupirira nthawi zowonongeka kwambiri
1. Symmetrical unsembe
2. Imatha kupirira katundu wozungulira;
3. Imatha kupirira katundu wa axial mbali ziwiri;
Imatha kupirira torque yayikulu;
Kuyika kwa Symmetrical 1
mazana awiri mphambu makumi atatu ndi anai
Wokhoza kupirira katundu wa radial;
Wokhoza kupirira katundu wa axial mbali ziwiri;
mtundu
Madoko okhoma a 7000C (x=15), 7000AC (x=25), ndi 7000B (x=40) ali pa mphete yakunja.Nthawi zambiri, mphete zamkati ndi zakunja sizingalekanitsidwe ndipo zimatha kupirira katundu wophatikizika wa radial ndi axial komanso katundu wa axial mbali imodzi.Kukhoza kupirira katundu wa axial kumatsimikiziridwa ndi ngodya yolumikizana, ndipo ngodya yaikulu yolumikizana imapangitsa kuti munthu athe kupirira katundu wa axial.Mtundu woterewu ukhoza kuchepetsa kusuntha kwa axial kwa shaft kapena chipolopolo kumbali imodzi.
