Tsarin kusurwa biyu yana ba wa kwalayen DA damar kama da kwalayen ER, amma suna da ƙarancin ƙarfin juyi. Ana amfani da su akai-akai a cikin tsoffin injunan niƙa da wasu mashinan haƙa rami, da kuma a aikace-aikacen ɗakin kayan aiki inda canje-canje cikin sauri ke da mahimmanci.
Muhimman halaye:
Kewayon rugujewa: har zuwa 0.8–1.0 mm (wanda aka kwatanta da ER)
Daidaiton gudu: yawanci 0.010–0.020 mm ga nau'ikan da aka saba
Ƙarfin juyi: ƙasa zuwa matsakaici - ba a ba da shawarar ga ƙarfin juyi mai ƙarfi ba
Aikace-aikace: niƙa mai sauƙi, haƙa, tapping, da ayyukan sakandare
Wani abin la'akari a aikace: Kwalayen DA suna buƙatar takamaiman goro da masu riƙewa, kuma ba za a iya musanya su da tsarin ER ko TG ba.
