Kuwonjezera pa zigawo zoyambira zoyambira, Timken yapanga njira zisanu zomwe zimagwiritsidwa ntchito kwambiri pokhazikitsa njira yoyambira yokha (monga SET-RIGHT, ACRO-SET, PROJECTA-SET, TORQUE-SET ndi CLAMP-SET) ngati njira zosinthira pamanja. Onani Gome 1- "Kuyerekeza njira zoyambira zoyambira zoyambira zoyambira" kuti muwonetse makhalidwe osiyanasiyana a njirazi mu mawonekedwe a tebulo. Mzere woyamba wa tebulo ili ukuyerekeza kuthekera kwa njira iliyonse kuwongolera moyenera "mtundu" wa njira yokhazikitsira yoyambira. Mitengo iyi imagwiritsidwa ntchito kokha kuwonetsa makhalidwe onse a njira iliyonse pakukhazikitsa njira yoyambira, mosasamala kanthu kuti njira yoyambira yakhazikitsidwa ku "preload" kapena "axial clearance". Mwachitsanzo, pansi pa gawo la SET-RIGHT, kusintha kwa njira yoyambira (yapamwamba kapena 6σ), chifukwa cha zowongolera zinazake zoyendetsera ndi housing/shaft tolerance, kumatha kuyambira mainchesi 0.008 mpaka mainchesi 0.014. Mtundu woyambira ukhoza kugawidwa pakati pa axial clearance ndi preload kuti muwonjezere magwiridwe antchito a bearing/application. Onani Chithunzi 5- "Kugwiritsa Ntchito Njira Yodziyimira Yokha Pokhazikitsa Kutsegula kwa Bearing". Chithunzichi chikugwiritsa ntchito kapangidwe ka thirakitala yaulimi yoyendetsedwa ndi mawilo anayi ngati chitsanzo kuti chiwonetse momwe njira yochotsera chotsekera cha bearing yozungulira yocheperako imagwirira ntchito.
Tikambirana mwatsatanetsatane matanthauzidwe enieni, malingaliro ndi njira zovomerezeka za njira iliyonse yogwiritsira ntchito m'mitu yotsatirayi ya gawoli. Njira ya SET-RIGHT imapeza chilolezo chofunikira powongolera kulekerera kwa bearing ndi makina oyika, popanda kufunikira kusintha pamanja TIMKEN tapered roller bearing. Timagwiritsa ntchito malamulo a kuthekera ndi ziwerengero kuti tilosere zotsatira za kulekerera kumeneku pa chilolezo cha bearing. Kawirikawiri, njira ya SET-RIGHT imafuna kuwongolera mwamphamvu kulekerera kwa machining kwa shaft/bearing housing, pomwe tikuwongolera mosamala (mothandizidwa ndi magiredi olondola ndi ma code) kulekerera kofunikira kwa ma bearing. Njirayi imakhulupirira kuti gawo lililonse mu assembly lili ndi kulekerera kofunikira ndipo liyenera kulamulidwa mkati mwa mtundu winawake. Lamulo la kuthekera likuwonetsa kuti kuthekera kwa gawo lililonse mu assembly kukhala kulekerera kochepa kapena kuphatikiza kulekerera kwakukulu ndi kochepa kwambiri. Ndipo tsatirani "kugawa kwabwinobwino kwa kulekerera" (Chithunzi 6), malinga ndi malamulo a ziwerengero, superposition ya kukula kwa magawo onse nthawi zambiri imakhala pakati pa kulekerera komwe kungatheke. Cholinga cha njira ya SET-RIGHT ndikulamulira kulekerera kofunikira kwambiri komwe kumakhudza chilolezo cha bearing. Zololera izi zitha kukhala zamkati mwa bearing, kapena zitha kukhala ndi zigawo zina zoyikira (monga, m'lifupi A ndi B mu Chithunzi 1 kapena Chithunzi 7, komanso m'mimba mwake wakunja wa shaft ndi bearing housing inner diameter). Zotsatira zake n'zakuti, ndi kuthekera kwakukulu, malo oyika bearing adzagwera mkati mwa njira yovomerezeka ya SET-RIGHT. Chithunzi 6.

Miyeso yonse yomwe imakhudza mtunda wolowera ma bearing mu assembly, monga ma bearing tolerances, shaft outer diameter, shaft length, bearing housing length, ndi bearing housing inner diameter, imaonedwa ngati yosiyana powerengera ma probability ranges. Mu chitsanzo chomwe chili mu Chithunzi 7, mphete zonse zamkati ndi zakunja zimayikidwa pogwiritsa ntchito njira yolumikizirana yokhazikika, ndipo chivundikiro chakumapeto chimangomangidwa kumapeto kwa shaft. s = (1316 x 10-6)1/2 = 0.036 mm3s = 3 x 0.036=0.108mm (0.0043 in) 6s = 6 x 0.036= 0.216 mm (0.0085 inches) 99.73% ya assembly (mwayi wolowera) nthawi yotheka = 0.654 Pa 100% ya mm (0.0257 inches) assembly (mwachitsanzo), sankhani 0.108 mm (0.0043 inches) ngati avareji ya mtunda wolowera.

Pambuyo powerengera ma probability range, kutalika kwa nominal kwa axial dimension kuyenera kutsimikiziridwa kuti mupeze bearing clearance yofunikira. Mu chitsanzo ichi, miyeso yonse kupatula kutalika kwa shaft imadziwika. Tiyeni tiwone momwe tingawerengere kutalika kwa nominal kwa shaft kuti mupeze bearing clearance yoyenera.
