Zogulitsa zamagalimoto zokhala ndi ma bearing, monga momwe zimakhalira ndi zigawo zogwirizana nazo, zonse mu radial ndi axial direction zimakhala ndi zoletsa zoyikira, zomwe zotsatira zake zidzakhudza kutseguka kwa bearing, zomwe zimawonekera poyera kutseguka koyamba kwa bearing ndi kusiyana pakati pachilolezo chogwira ntchito.
Mpata mu bearing ndi mtunda wonse womwe mphete imodzi yonyamulira imatha kusuntha mozungulira kapena mozungulira poyerekeza ndi mphete ina yonyamulira. Ponena za mpata wa bearing, kusiyana kuyenera kupangidwa pakati pa mpata musanayike ndi mpata mutayike ndikufika kutentha kwake kogwira ntchito. Mpata wogwirira ntchito wa bearing nthawi zambiri umakhala wocheperapo kuposa mpata woyambira chifukwa cha kulekerera komwe kumayenderana ndi kuchuluka kosiyanasiyana kwa kusokoneza ndi madigiri osiyanasiyana a kutentha kwa mphete zonyamulira ndi zigawo zina zogwirizana nazo (monga ma mota shaft, ma end caps, ndi zina zotero), zomwe zimapangitsa kuti mphete ikule kapena kupsinjika.
Mfundo zazikulu zoyendetsera ndi luso: Kutuluka kwa ma bearing a mpira kuyenera kukhala zero kapena kukhala ndi kuyika pang'ono. Komabe, pa ma bearing a cylindrical roller, spherical roller ndi ma bearing ena, payenera kukhala malo ena otsalira omwe akugwira ntchito, ngakhale atakhala ochepa kwambiri.
Kawirikawiri pansi pa mikhalidwe yabwinobwino yogwirira ntchito, chilolezo choyenera chogwirira ntchito chingapezeke posankha mabearing okhala ndi chilolezo chofanana cha gulu. Komabe, pamenemikhalidwe yogwirira ntchito ndi yoyikiraNgati mabearing a mphete zonse ziwiri ali ndi vuto losokoneza, kapena kusiyana kwa kutentha kwa mphete kumakhudza kwambiri, ndiye kuti malo olowera ayenera kusankhidwa kusiyana ndi gulu la mabearing akuluakulu kapena ang'onoang'ono.
Kutengera ndi momwe ntchito ikuyendera, ma bearing ayenera kukonzedwa ndi chilolezo chogwira ntchito chabwino kapena choipa. Nthawi zambiri, chilolezo chogwira ntchito chiyenera kukhala chabwino, mwachitsanzo, bearing iyenera kugwira ntchito ndi chilolezo chotsalira. Kumbali ina, pali ntchito zambiri zomwe zikufunika chilolezo chogwira ntchito choyipa - mwachitsanzo preload -.
Kuyika ma bearing pasadakhale kungagwiritsidwe ntchito kuwonjezera kulimba kapena kulondola kwa ma bearing configuration. Zitsanzo zikuphatikizapo ma spindle bearing mu zida zamakina, ma pinion bearing mu automotive driveshafts, ma bearing mu ma motors ang'onoang'ono, kapena ma bearing configuration kuti ayende mozungulira. Mu ntchito zina kumene ma bearing sali, kapena amangogwiritsidwa ntchito, ndi katundu wochepa kwambiri ndipo amayendetsedwa ndi liwiro lalikulu, preload iyenera kugwiritsidwa ntchito pakasinthidwe ka berePankhaniyi, cholinga choyika zinthu pasadakhale ndikupereka katundu wochepa kwambiri pa bearing kuti zinthu zozungulira zisagwedezeke ndikuwononga bearing.
Kuyika zinthu patsogolo kungakhale kozungulira kapena kozungulira kutengera mtundu wa kuberekera. Mwachitsanzo, ma bearing a cylindrical roller, amatha kuyika zinthu patsogolo polowera mbali ya radial chifukwa cha kapangidwe kake, pomwe ma bearing a mpira wopindika ndi ma bearing a cylindrical roller thrust amatha kuyika zinthu patsogolo polowera mbali ya axial. Ma bearing a mpira wolumikizana ndi mzere umodzi ndi ma bearing a roller opindika nthawi zambiri amayikidwa mu axial preload ndipo nthawi zambiri amagwiritsidwa ntchito m'mawiri awiri kumbuyo kapena nkhope ndi nkhope ndi bearing ina yamtundu womwewo. Ma bearing a mpira wozama nthawi zambiri amagwiritsidwanso ntchito ndi axial preload yomweyo, kuti akwaniritse cholinga choyika zinthu patsogolo, ayenera kugwiritsidwa ntchito ndi gulu lalikulu kuposa wamba la radial internal clearance, kotero kuti likhoza kukhala ngati ma bearing a mpira wolumikizana ndi angular ali ndi ngodya yolumikizana yoposa zero.
