Applications

Iyo yekuwachisa yechirimo inodzivirira nzungu nemabhaudhi kubva pakutendeuka, kutsvedza nekubuda zvakasununguka nekuda kwekudengenyeka uye torque. Mawashi echitubu akasiyana anoita basa iri nenzira dzakasiyana, asi pfungwa huru ndeyekubata nati nebhaudhi panzvimbo. Mamwe mawashi echitubu anozadzikisa basa iri nekuruma muhwaro zvinhu (bhaudhi) uye nati nemagumo adzo.

Mawashi echitubu anowanzo shandiswa mumashandisirwo anosanganisira vibration uye zvinogoneka kutsvedza kwemafasteners. Maindasitiri anowanzo kushandisa mawachi echirimo ane chekuita nezvekufambisa (mota, ndege, dzemugungwa).
