ʻO ka huila hoʻopili ponoʻī he lālani ʻelua o nā wili, ʻo ke apo o waho he raceway spherical maʻamau, ʻo ke apo i loko ʻelua mau ala heihei a ua hili ʻia ma kahi Angle e pili ana i ke axis bearing. Hana ʻia kēia ʻano akamai i ka hana aligning maʻalahi, no laila ʻaʻole maʻalahi ke hoʻopili ʻia e ka Angle o ka shaft a me ka noho pahu pahu ma ka hewa a i ʻole ke kuʻi ʻana o ka shaft, a kūpono ia no ka hoʻonohonoho hewa ʻana a i ʻole ka hoʻololi ʻana o ka shaft i hana ʻia e nā manawa hewa Angle. Ma waho aʻe o ka ukana radial, hiki i ka bearing ke halihali i ka ukana axial o ka hana bidirectional.
ʻO nā noi nui: ka mīkini hana pepa, ka mea hoʻemi, ka axle kaʻa kaʻa, ka pahu wili pahu pahu e lawe ana i ka noho, ka wili wili wili, crusher, vibrating screen, mīkini paʻi, mīkini hana lāʻau, nā ʻano mea hoʻohaʻahaʻa ʻoihana āpau, kūpaʻa kūlike me ka noho.
