Ho khetha li-bearings bakeng sa mechini e boima ho hloka mokhoa o hlophisitsoeng oa boenjiniere ho fapana le ho leka le ho etsa liphoso.
Mohato oa 1: Hlalosa Maemo a Mojaro
Etsa qeto:
- Mojaro o sa fetoheng (matla a phahameng ka ho fetisisa ha motho a phomotse)
- Mojaro o matla (maemo a ts'ebetso)
- Mejaro ea ho tšoha (matla a tšusumetso)
Mokhatlo oa Machaba oa Maemo a Tekanyetso (ISO) o fana ka maemo a lipalo tlas'a ISO 281.
