ʻO nā bearings kekahi o nā ʻāpana koʻikoʻi loa o nā huahana motika. Hoʻokau nā kūlana hana kūikawā i nā koi kiʻekiʻe loa i nā bearings ponoʻī a me kā lākou lubrication. No ka laʻana, nā wahi wela kiʻekiʻe, nā wahi wela haʻahaʻa, nā loli wela nui, a me nā wahi me nā mea haumia e hōʻike ana i nā kūlana kūikawā e pono ai ke koho pono ʻana i nā bearings. Ua hoʻomohala kekahi mau mea hana bearing i nā bearings kumu kūikawā kūpono no kēia mau kūlana. He ʻike koʻikoʻi kēia e pono ai nā mea hoʻolālā motika ke hoʻomaopopo a aʻo e pale aku i ka hilinaʻi ʻole o ka motika i hoʻokumu ʻia e ke koho bearing kūpono ʻole.
ʻO nā bearings pōpō hohonu hohonu i kūpono no nā mahana kiʻekiʻe a me nā mahana haʻahaʻa ua hoʻolālā ʻia ma ke ʻano like me nā bearings pōpō hohonu hohonu maʻamau. Ua lako kēia mau bearings me kahi hoʻolālā e hōʻike ana i kahi hakahaka hoʻouka pōpō, hiki ke kū i nā ukana radial waena a me nā ukana axial ma nā ʻaoʻao ʻelua. Loaʻa iā lākou kahi ākea kūloko nui a ua hoʻolako ʻia me nā cages kūikawā. ʻO ka laulā ʻae o nā bearings pōpō hohonu hohonu wela kiʻekiʻe he ʻehā manawa o ka ʻae C5, e pale ana i nā bearings mai ka paʻa ʻana i ka wā hoʻomaʻalili wikiwiki. Hoʻohana ʻia nā ʻili o nā bearings a me nā uhi lepo me ka manganese phosphating e pale aku i ka pala a hoʻomaikaʻi i ka hana hana. No nā bearings wela kiʻekiʻe a me ka mahana haʻahaʻa me nā cages kila i kaomi ʻia a me nā sila ʻole, hoʻohana ʻia kahi hui o ka polydiol a me ka graphite ma ke ʻano he lubricant, a hiki iā lākou ke hana i loko o kahi pae mahana o -40°C a i 250°C. Eia naʻe, i ka wā e hoʻohana ʻia ai i nā wahi wela kiʻekiʻe ma luna o 200°C, pono e koho ʻia nā lubricants paʻa.
Hiki i nā bearings wela kiʻekiʻe me nā uhi lepo ma nā ʻaoʻao ʻelua ke pale i kekahi mau mea haumia paʻa mai ke komo ʻana. Ua hoʻopiha mua ʻia kēia mau bearings me ka pālua o ka nui o ka lubricant ma mua o nā bearings maʻamau, akā ʻaʻole kūpono lākou no nā noi ʻaʻole e wili. No nā bearings i hoʻohana ʻia i nā mahana kiʻekiʻe, hoʻohana ʻia nā poloka graphite i ʻāpana ʻia e like me nā mea paʻa hale paʻahao. ʻO ka pae mahana hana mai -150°C a i +350°C. Hoʻokaʻawale kēia mau poloka graphite i ʻāpana ʻia i nā pōpō a hana e like me ka hale paʻahao maʻamau, a lawelawe pū kekahi ma ke ʻano he lubricant. Hiki i nā uhi lepo ma nā ʻaoʻao ʻelua o nā bearings ke alakaʻi axial i nā poloka graphite i loko a pale i ke komo ʻana o nā mea haumia paʻa. Ke wili nā bearings, hāʻule kahi liʻiliʻi o ka pauka graphite mai nā poloka graphite e lubricate i nā raceways a me nā pōpō o nā bearings. ʻO kekahi pono o kēia hoʻolālā, ʻaʻohe ona hopena maikaʻi ʻole i ke kaiapuni, ʻoiai ʻaʻohe kinoea a mahu ʻino i hoʻokuʻu ʻia ʻoiai i nā mahana kiʻekiʻe loa.
ʻO kēia bearing, kūpono no nā mahana kiʻekiʻe a me nā wikiwiki wili kiʻekiʻe, ʻo ia ka huahana ʻoi loa i ka moʻo bearing wela kiʻekiʻe. Hōʻike ia i kahi pā conical graphite maʻemaʻe i hoʻolālā kūikawā ʻia, kahi e hoʻoponopono ai i nā palena he nui i loaʻa i nā noi ma nā mahana kiʻekiʻe.
