Bithear a’ cleachdadh nigheadairean earraich gu cumanta gus casg a chuir air looseness: Bidh nigheadairean earraich a’ toirt seachad neart teannachaidh a bharrachd gus cuideachadh le casg a chuir air bholtaichean no chnothan a bhith air an leigeil ma sgaoil air sgàth crith no nithean eile. Lùghdaich crathadh: lughdaich nigheadairean earraich crathadh ann an innealan meacanaigeach, lughdaich a’ bhuaidh air pàirtean ceangail, gus pàirtean a dhìon bho mhilleadh. Cuideam sgaoilte: Tha ìre sònraichte de elasticity aig nigheadairean earraich, faodaidh iad neart teannachaidh a ’chuideam a sgaoileadh, cuideachadh gus na pàirtean ceangail a dhìon. Atharraich am feachd teannachaidh: faodar an inneal-nigheadaireachd earraich a chleachdadh cuideachd gus am feachd teannachaidh atharrachadh, gus dèanamh cinnteach gum faigh na pàirtean ceangail an cuideam iomchaidh. San fharsaingeachd, tha àite cudromach aig nigheadairean an earraich ann an grunn innealan meacanaigeach gus dèanamh cinnteach à sàbhailteachd agus earbsachd pàirtean ceangail
