ʻO ka rigidity o kahi bearing ka ikaika e pono ai e hana i ka deformation bearing.He liʻiliʻi loa ka deformation elastic o nā bearings rolling a hiki ke nānā ʻole ʻia i ka hapa nui o nā mīkini.Eia nō naʻe, i kekahi mau mīkini, e like me nā mīkini mea hana spindles, he mea koʻikoʻi ke kau ʻana i ka rigidity.Hoʻohana maʻamau ʻia nā bearings cylindrical a tapered roller.No ka mea ua kau ʻia nā ʻano bearings ʻelua i ka ukana, ʻo nā mea ʻōwili a me nā raceways e pili ana i ka laina laina, a liʻiliʻi ka deformation elastic a maikaʻi ka rigidity.Hiki ke hoʻopaʻa ʻia nā ʻano bearings āpau e hoʻonui i ka rigidity o ke kākoʻo.ʻO kahi laʻana, nā bearings ball contact angular a me nā bearings roll tapered, i mea e pale ai i ka haʻalulu o ke kumu a hoʻonui i ka rigidity o ke kākoʻo, hoʻohana pinepine ʻia kekahi ikaika axial i ka manawa o ka hoʻokomo ʻana e paʻi iā lākou i kekahi i kekahi.ʻOiaʻiʻo, ʻaʻole pono e nui ka nui o ka pre-tightening.Inā nui loa ia, e piʻi aʻe ka friction bearing a piʻi ka piʻi ʻana o ka mahana, e pili ana i ke ola lawelawe o ka bearing.
