Loaʻa i nā bearings pōpō ʻehā-contact i kahi apo o loko i māhele ʻia i ʻelua ʻāpana. Hoʻokahi wale nō o kēia mau bearings hiki ke hoʻomau i nā ukana axial nui ma nā ʻaoʻao ʻelua. hiki ke hoʻopaʻa kaʻawale ʻia ke apo o waho me ka pōleʻa a me ka hui hale mai nā ʻāpana apo ʻelua. Hiki i kahi kihi pili o 35 ° ke hiki ke hoʻouka axial kiʻekiʻe. Ua kūpono kēia ʻano no ka lawe ʻana i nā ukana axial maʻemaʻe a i ʻole nā ukana i hui pū ʻia i kahi kiʻekiʻe o ka ukana axial.
