Ebika by'okusitula omupiira ogw'okusika .

Okusinziira ku mpisa z’omugugu, bbeeri z’omupiira ezisindikiddwa zigabanyizibwa mu bbeeri z’omupiira gw’okusika okw’oludda olumu n’eza bidiriya. unidirectional thrust ball bearings zisobola okugumira emigugu egy’ekyekulungirivu egy’oludda olumu. Bidirectional thrust ball bearings, nga mu bino ebinaabirwamu ebinaabirwamu biyungiddwa ku shaft, bisobola okugumira bidirectional axial loads. Bearings ezirina spherical mounting surfaces ku seat washers ziwa self-okukwatagana eby'obugagga, okukendeeza ku impact y'ensobi z'okuteeka. Thrust ball bearings teziyinza kugumira radial loads era zirina sipiidi esinga obunene.
