Mabda'a shaqada ee taxanaha STM ee labajibbaaran aluminium daawaha pneumatic cylinder waa in loo beddelo tamarta kinetic ee gaasta tamarta dhaqdhaqaaqa farsamada iyada oo loo marayo wadista pneumatic. Marka gaasku uu galo dhululubada, shayga shaqada ee dhululubada ayaa si toos ah ugu dhaqaaqa riixitaanka piston-ka. Naqshadaynta dhidibka labanlaabka ah ee dhululubada ayaa ka dhigaysa dhululubada inay yeelato hufnaan shaqo oo sarreeya iyo saxsanaan.
STM taxane aluminium aluminium pneumatic dhululubo leh fal axial double ayaa si weyn loo isticmaalaa in nidaamyada gacanta si toos ah, sida khadadka wax soo saarka warshadaha, qalabka farsamada, iwm Waxay leedahay faa'iidooyinka size yar yar, miisaanka fudud iyo qaab-dhismeedka fudud, oo dabooli kara baahida kala duwan. goobaha shaqada.
