Xajinta xajinta ayaa lagu rakibay inta u dhaxaysa xajinta iyo gudbinta.Kursiga lagu sii daayo waxa uu si dabacsan ugu xidhan yahay fidinta tuubada ee daboolka xadhkaha ugu horreeya ee gudbinta.Garabka siidaynta ayaa had iyo jeer ka soo horjeeda fargeetada la sii daayo iyada oo loo marayo guga soo laabashada oo dib ugu noqda booska ugu dambeeya., Ku hay farqiga qiyaastii 3 ~ 4mm dhamaadka kabaalka kala soocida (farta kala goynta).Tan iyo markii saxan cadaadis xajin, kabaalka sii daayo iyo crankshaft engine si siman u shaqeeyaan, iyo fargeeto sii daayo kaliya dhaqaaqi kartaa axially weheliyaan usheeda dhexe wax soo saarka xajin, waxaa cad in aan macquul ahayn in si toos ah loo isticmaalo fargeeto sii daayo si aad u garaacdo kabaalka sii daayo.Qaadashada sii deynta ayaa ka dhigi karta kabaalka sii daynta inuu u wareego dhinac.Usha wax soo saarka ee xajintu waxay u socotaa axially, taas oo hubinaysa in xajintu ay si habsami leh u shaqeyn karto, si tartiib ah uga bixi karto, yareyso xirashada, oo kordhiso nolosha adeegga xajinta iyo dhammaan tareenka wadista.
Xirmooyinka VSPZ waxaa loo isticmaalaa Lada, Kia, Hyundai, honda, Toyota, renault, dacia, fiat, opel, VW, peugeot, citroen iyo iwm.
Xadhkaha VSPZ kastaa wuxuu la kulmaa ISO:9001 IYO IATF16949 heerarka tayada.
