Ama-roller bearings athambile ngokuvamile asetshenziselwa ukusekela umthwalo ohlangene oqukethe umthwalo we-radial. Izinkomishi zawo ziyahlukaniswa ukuze kube lula ukuhlanganisa. Ngesikhathi sokufaka nokusebenzisa, ukuhlukaniswa kwe-radial kanye nokuhlukaniswa kwe-axial kungalungiswa futhi ukuphakanyiswa okulayishiwe kusengaphambili kungenziwa.
