Giraanta piston-ka ayaa ku celisa bisinka ku jira dhululubada, taas oo sababta in dusha sare ee shaqada ee giraanta piston ay xirto, dhumucda radial ee giraanta ayaa hoos u dhacda, farqiga u dhexeeya furitaanka shaqada ee giraanta piston ayaa kordha; Dusha sare ee hoose waa la gashadaa, dhererka axial ee giraanta ayaa hoos u dhacda, iyo farqiga u dhexeeya giraanta iyo giraanta giraanta, taas oo ah, farqiga diyaaradda ayaa kordha. Caadiyan, heerka xidhashada caadiga ah ee giraanta piston waxay ku dhex jirtaa 0.1-0.5mm /1000h marka matoorka naaftada uu si caadi ah u shaqeeyo, iyo nolosha giraanta piston guud ahaan 8000-10000h. Giraanta bistoonka ee sida caadiga ah xidhan waxa ay si siman u xidhan tahay jihada wareegta ah walina waxa ay si buuxda ugu xidhan tahay gidaarka dhululubada, sidaa awgeed giraanta piston-ka ee xidhan waxa ay wali leedahay saamayn xidhidh. Laakiin dhab ahaantii, dusha sare ee shaqada ee wareegga dibadda ee giraanta piston inta badan waa mid aan sinnayn.
Kahor intaadan cabbirin farqiga u dhexeeya furaha giraanta piston, ① ka saar bisinka dhululubada, ka saar giraanta bistoonka oo nadiifi giraanta piston-ka iyo xadhkaha dhululubada. ② Geli giraanta piston giraanta qaybta ugu yar ee gashanayd ee qaybta hoose ee xadhkaha dhululubada ama qaybta aan xidhnayn ee qaybta sare ee xadhkaha dhululubada iyadoo la raacayo nidaamka faraantiyada biistoonka, oo ilaali giraangiraha bistoonka oo ku yaal meel siman.
③ Isticmaal cabirka dareemaha si aad u cabbirto fur-furka giraanta piston kasta markeeda. ④ Is barbar dhig qiimaha faraqa furitaanka ee la cabbiray qeexida ama heerka. Marka qiimaha nadiifinta xadka la dhaafo, waxay la macno tahay in dusha sare ee giraanta piston si xad dhaaf ah loo xidhay oo waa in mid cusub lagu beddelaa. Waxaa guud ahaan loo baahan yahay in qiimaha furista giraanta piston uu ka weyn yahay ama la siman yahay nadiifinta golaha oo ka yar fasaxa xadka. Ogsoonow in haddii faraqa furitaanka uu aad u yar yahay, laguma hagaajin karo marka la xereeyo furitaanka giraanta piston.
