M'makampani opanga zinthu, anthu ena amaganiza kuti zozungulira zozungulira ndizofala kwambiri kuposa zomangira zathyathyathya, kuyambira zomangira, mtedza, ma gaskets, masilinda ndi ma bearing. Kugwiritsa ntchito zozungulira zozungulira ndikokwera kwambiri.
Pazigawo zozungulira izi, nkhani yofulumira kwambiri yomwe ikufunika kuthana ndi momwe mungawunikire mawonekedwe awo ozungulira. Lero, tikuwonetsa zizindikiro ndi matanthauzo okhudzana ndi kuzungulira (miyezo yolozera: ISO/DIS 1101:2017, ISO 5459)
Kuzungulira
Kutulutsa kwa circumference kuyenera kungokhala gawo lololera pakati pa mabwalo awiri ozungulira a coplanar okhala ndi kusiyana kwa radius ya t.

Kuwongoka
Mphepete zomwe zimachotsedwa pamtunda wa cylindrical ziyenera kungokhala pamalo olekerera pakati pa mizere iwiri yofanana ndi mtunda wa t kumbali yomwe yatchulidwa.
Kusalala
Ndilo dera lomwe lili pakati pa ndege ziwiri zofanana ndi mtunda wa mtengo wololera t.
Cylindricity
Kuchotsa kwa cylindrical pamalo kuyenera kungokhala kumalo olekerera omwe amapangidwa pakati pa malo awiri a coaxial cylindrical okhala ndi kusiyana kwa radius ya t.
Concentricity
Malo ochotsamo bwalo ayenera kukhala ochepa mkati mwa malo olekerera omwe amapangidwa ndi bwalo lokhala ndi mainchesi a t omwe ali okhazikika ndi zomwe zimatchulidwa.
Coaxiality
Mzere wochotsedwa uyenera kukhala wocheperako mkati mwa malo olekerera omwe amapangidwa ndi cylindrical pamwamba ndi mainchesi a t omwe ali coaxial ndi mawuwo.
kuima
Mzere wochotsedwa uyenera kukhala wocheperako kudera lololera lopangidwa ndi cylindrical pamwamba ndi mainchesi a t ndi perpendicular kwa ndege yolozera.
