Ƙaƙƙarfan ƙwallo abubuwa ne na inji waɗanda ke rage juzu'i kuma suna ba da damar ramuka da sanduna su juya sumul. Akwai manyan nau'ikan ƙwallo guda biyu: Ƙwallon ƙwallon ƙafa na kusurwa da zurfin tsagi. Sun bambanta a cikin ƙira, aiki da aikace-aikace.
Ƙwallon ƙwallon ƙafa na kusurwa yana da ɓangaren giciye asymmetric, kuma akwai kusurwoyin tuntuɓar tsakanin zoben ciki, zobe na waje da ƙwallan ƙarfe. Ƙaƙwalwar lamba tana ƙayyade ƙarfin ɗaukar nauyi na axial. Girman kusurwar lamba, mafi girman ƙarfin nauyin axial, amma ƙananan saurin gudu. Ƙwallon ƙwallon ƙafa na kusurwa na iya ɗaukar nauyin radial da axial, kuma ana iya amfani da su bibiyu don ɗaukar nauyin axial na bidirectional. Ƙwallon ƙwallon ƙafa na kusurwa sun dace da babban sauri, aikace-aikacen madaidaici kamar kayan aikin injin, famfo da compressors.
Ƙwallon ƙwallo mai zurfi yana da ɓangaren giciye mai ma'ana da ƙaramin kusurwar lamba tsakanin zoben ciki da na waje da ƙwallan ƙarfe. Matsakaicin lamba yawanci yana kusa da digiri 8, wanda ke nufin ɗaukar nauyi kawai zai iya ɗaukar ƙaramin axial. Ƙwallon ƙwallon ƙafa mai zurfi na iya jure manyan lodin radial da matsakaicin nauyin axial a dukkan kwatance. Ƙwallon ƙwallon ƙafa mai zurfi ya dace da ƙananan amo da ƙananan aikace-aikacen girgiza kamar injin lantarki, masu jigilar kaya da magoya baya.
Babban fa'idodin ƙwallon ƙwallon ƙafa na kusurwa sama da zurfin tsagi ball bearings sune:
• Ƙarfin nauyin nauyin axial mafi girma
• Kyakkyawan tsauri da daidaito
• Ƙarfin ɗaukar nauyin haɗuwa
Babban fa'idar zurfin tsagi ball bearings sama da angular lamba bear bearings su ne:
• Rage gogayya da samar da zafi
• Iyakoki mafi girma
• Mafi sauƙin shigarwa da kulawa
