Kuphatikiza pa ntchito ya deep groove mpira wonyamula katundu wa radial, mphete yoyimitsa imatha kuchepetsa kusuntha kwa axial, kumathandizira kapangidwe kake ka axial ka mpando ndikuchepetsa kukula kwa axial.

Mpira wokhazikika wa deep-groove wokhala ndi stop groove uli ndi dzina lakumbuyo la N, ndipo mpira wakuya-groove wokhala ndi poyimitsa ndi mphete yoyimitsa uli ndi dzina lakumbuyo la HR.Kuphatikiza apo, pali ZN, ZNR ndi mitundu ina yamapangidwe.Kuphatikiza pa kunyamula katundu wa radial, mpira wokhala ndi mphete yoyimitsa ukhoza kuchepetsa kusuntha kwa axial, kumathandizira kapangidwe kake ndikuchepetsa kukula kwake.Nthawi zambiri amagwiritsidwa ntchito pamagalimoto, mathirakitala ndi katundu wina wa axial sizinthu zazikulu zantchitoyo.
