Ma bearing amagawika m'magulu anayi: ma bearings ogudubuza, ma plain bears, amakona olumikizana, ndi -zodziyendetsa okha. Zopiringa zimagwiritsa ntchito zinthu zogudubuza (monga zodzigudubuza ndi mipira yachitsulo) kuti achepetse kukangana ndipo ndi oyenera{2}}kuthamanga,{3}}kuthamanga kwambiri. Mwachitsanzo, mayendedwe a mpira wakuya (wothamanga mpaka 20,000 rpm) amagwiritsidwa ntchito m'magalimoto oyendetsa galimoto, pamene mayendedwe odzigudubuza (ndi 30% kuwonjezeka kwa katundu) ndi oyenera makina olemera. Ma bearings opanda kanthu amapangidwa kuchokera ku -zinthu zosweka kwambiri (monga ma copper alloys ndi polytetrafluoroethylene). Zonyamula manja za graphite sizimatentha-zosamva kutentha (kutentha kwa ntchito Kusakwana kapena kofanana ndi madigirii 500). Mafuta-ma bearings amafuta amatha kugunda kwambiri-kutsika kwambiri (friction coefficient <0.001) pogwiritsa ntchito filimu yamafuta, kuwapanga kukhala oyenera zida zolondola kwambiri. Miyendo yolumikizana ndi ma angular imatha kupirira zopinga zonse za ma radial ndi axial (makona olumikizana ndi madigiri 15 -40 degrees ) ndipo amagwiritsidwa ntchito kwambiri pamipingo ya zida zamakina. Self-ma bere a mpira amakhala ndi ntchito yodziyang'ana yokha (yokhala ndi mbali yokhotakhota yolipirira digirii 2 -3 ) ndipo ndi yoyenera kumalo onjenjemera monga makina akumigodi.
