Mizere iwiri ya cylindrical roller yonyamula imatha kunyamula katundu wamkulu wa du munjira yolowera.Amalola mizere iwiri ya DAO odzigudubuza mu kubala ndi liwiro mkulu kukonzedwa mu njira mtanda.Kusinthasintha kwafupipafupi panthawi yozungulira kumakhala kowirikiza kawiri kuposa kwa mzere umodzi, ndipo matalikidwe amachepetsedwa ndi 70%.

Pali mitundu iwiri ya mayendedwe omwe amagwiritsidwa ntchito wamba: NN30/W33 ndi NN30K/W33 mndandanda.NNU49/W33 ndi NNU49K/W33 mndandanda wokhala ndi mphete yakunja ndi m'mphepete, mphete yamkati imatha kupatulidwa, NN30K/W33 ndi NNU49K/W33 mndandanda wamkati mphete ndi mabowo opindika (taper 1:12), omwe amagwirizana ndi magazini ya conical ya spindle. .Kusuntha kwa axial kwa mphete yamkati kumatha kupangitsa kuti mphete yamkati ikule kuti ichepetse kutulutsa komanso ngakhale kukulitsa kunyamula.

Ma cylindrical bore bearings nthawi zambiri amakhala odzaza ndi kutentha, ndipo kusokoneza kumagwiritsidwa ntchito kuchepetsa chilolezo cha kunyamula kapena kukwaniritsa cholinga chokweza.Zonyamula za NNU49 zokhala ndi mphete zamkati zomwe zimatha kuchotsedwa nthawi zambiri zimapangidwira pamseu wothamanga pambuyo poyika spindle pa mphete yamkati kuti apeze kulondola kwakukulu kozungulira.
