2. Mbewu yomwe imagwiritsidwa ntchito pokonza njira yonyamula mphamvu idzayesedwa ndi 2 nthawi yomwe idavotera ngati katundu wowunikira.
3. Pambuyo pambezaamachotsedwa pa katundu woyendera, sikuyenera kukhala ndi zolakwika zoonekeratu kapena kupunduka, ndipo kuwonjezeka kwa digiri yotsegulira sikuyenera kupitirira 0.25% ya kukula koyambirira.
4. Pakutimbedzazomwe zadutsa kuyendera, chizindikiro chiyenera kusindikizidwa m'dera lochepetsetsa la mbedza, kuphatikizapo kulemera kwake, chizindikiro cha fakitale kapena dzina la fakitale, chizindikiro choyendera, nambala yopangira, ndi zina zotero.
Ambezaiyenera kujambulidwa pamene chimodzi mwazomwe zimachitika:
① Mng'alu;
②dasesseous gawo lomwe limavala malita 10% ya kukula koyambirira;
Diti yotseguka imachulukitsidwa ndi 15% poyerekeza ndi kukula koyambirira;
④Kusinthika kwa torsion kwa thupi la mbedza kumapitilira 10 °;
⑤Gawo lowopsa la mbedza kapena khosi la mbedza ndi lopunduka mwapulasitiki;
⑥Ulusi wa mbeza wachita dzimbiri;
Zovala za hook bush zimafika 50% ya kukula koyambirira, bushing iyenera kusinthidwa;
⑧ Pamene mandrel a chidutswachombezaimavala mpaka 5% ya kukula koyambirira, mandrel iyenera kusinthidwa.
